Question 1

How quickly can you get to my home for an AC repair?

Accepted Answer

We offer same-day service for most calls and 24/7 emergency AC repair. In most cases, a technician can be at your door within a few hours of your call.

Question 2

Do you repair all AC brands?

Accepted Answer

Yes. Our technicians are trained to work on all major brands including Trane, Carrier, Lennox, Rheem, Goodman, and more.

Question 3

How do I know if my AC needs repair or replacement?

Accepted Answer

If your system is over 15 years old and requires frequent repairs, replacement may be more cost-effective. We'll give you an honest assessment and help you weigh repair vs. replacement costs.

Question 4

Why is my AC running but not cooling my house?

Accepted Answer

The most common causes are a dirty air filter restricting airflow, low refrigerant from a leak, a dirty condenser coil outside, or a failed compressor. Start by checking your filter — if it's clogged, swap it out and give the system 30 minutes to recover. If it's still not cooling, you likely need a professional diagnosis to check refrigerant levels and electrical components.

Question 5

Why is my AC blowing warm air?

Accepted Answer

Warm air from your vents usually points to low refrigerant, a failed compressor, a tripped breaker to the outdoor unit, or a thermostat set incorrectly. Check that your thermostat is set to 'cool' (not 'heat' or 'fan only') and that the outdoor unit is running. If the outdoor unit isn't running or the air stays warm, call us — refrigerant leaks and compressor failures require professional repair.

Question 6

Why is my AC blowing hot air suddenly?

Accepted Answer

A sudden switch to hot air often means your outdoor unit lost power — check the breaker and the disconnect box next to the unit. It can also indicate a capacitor failure, which prevents the compressor from starting. In heat pump systems, a stuck reversing valve can cause the system to blow hot air in cooling mode. Any of these require same-day service to avoid compressor damage.

Question 7

My AC is cooling but not enough — rooms are still warm. Why?

Accepted Answer

Insufficient cooling is usually caused by an undersized system, duct leaks losing conditioned air to the attic or crawlspace, a dirty evaporator coil, or low refrigerant. In Asheville's humid summers, a system that's low on charge will lose both cooling capacity and dehumidification ability. We can perform a full system evaluation to identify where the problem lies.

Question 8

Why does my AC cool some rooms but not others?

Accepted Answer

Uneven cooling is almost always a ductwork problem — either leaky ducts, improperly sized ducts, or dampers that need balancing. It can also be caused by a blower motor running at the wrong speed or an undersized system struggling on the hottest days. We check airflow at every register and inspect the duct system to find the root cause.

Question 9

Why is my AC unit freezing up?

Accepted Answer

An AC freezes when something disrupts the heat exchange process — most commonly a dirty air filter, low refrigerant, or a blower motor that isn't pushing enough air across the evaporator coil. The coil temperature drops below 32°F and moisture in the air freezes on it. Turn the system off, let it thaw completely (this can take several hours), replace your filter, and restart. If it freezes again, you likely have a refrigerant leak that needs professional repair.

Question 10

What causes ice to form on my AC's indoor coil?

Accepted Answer

Ice on the evaporator coil is caused by inadequate airflow or low refrigerant charge. Restricted airflow — from a clogged filter, closed vents, or a failing blower motor — prevents warm house air from reaching the coil. Low refrigerant drops the coil temperature below freezing. Either way, running the system with ice on the coil can damage your compressor, so shut it down and call for service.

Question 11

Why does my outdoor AC unit have ice on it in summer?

Accepted Answer

Ice on the outdoor unit in summer is abnormal and almost always indicates a serious refrigerant leak. The refrigerant pressure drops so low that the liquid line and even the compressor freeze over. This is not a situation you should ignore — running a system with severely low refrigerant will burn out the compressor, turning a $300 repair into a $2,000+ replacement.

Question 12

How do I safely thaw a frozen AC unit?

Accepted Answer

Turn off the cooling at the thermostat and switch the fan to 'ON' — this circulates warm air across the coil to speed thawing. Do not try to chip ice off the coil, as the fins are fragile. Full thawing typically takes 2-4 hours. Once thawed, check your filter and replace it if dirty. If the system freezes again after restarting, call us — you likely have a refrigerant leak or blower issue.

Question 13

Why is my AC leaking water inside my house?

Accepted Answer

Indoor water leaks are almost always caused by a clogged condensate drain line. Your AC removes gallons of moisture from the air daily, and that water drains through a PVC line. When algae, mold, or debris clogs it, water backs up into the drain pan and overflows. We clear the drain, treat it to prevent regrowth, and check the drain pan for cracks. This is a common repair that usually takes less than an hour.

Question 14

Why is there water pooling around my indoor AC unit?

Accepted Answer

Water around the indoor unit typically means a clogged drain line, a cracked drain pan (common on units over 12 years old), or the unit isn't level. If your system has a secondary drain line or a float switch, the switch should shut the unit off before flooding occurs — if it didn't, the switch may need replacement. Don't ignore indoor water leaks, as they can cause mold growth and ceiling or floor damage.

Question 15

Is it normal for my outdoor AC unit to leak water?

Accepted Answer

Some condensation dripping from the outdoor unit is normal, especially on humid Asheville summer days. However, a large amount of water pooling around the outdoor unit can indicate a refrigerant leak causing the coil to freeze and then thaw, or a blocked drain on a heat pump system. If the water is excessive or you see ice, call for service.

Question 16

Why won't my AC turn on at all?

Accepted Answer

Start with the basics: check that the thermostat is set to 'cool' with the temperature set below room temperature, verify the breaker hasn't tripped, and make sure the indoor and outdoor disconnect switches are in the 'on' position. If everything looks right, the most common causes are a failed capacitor, a blown contactor, a tripped safety switch, or a faulty thermostat. These are all components our technicians carry on their trucks for same-day repair.

Question 17

My thermostat is blank — is that why my AC won't start?

Accepted Answer

A blank thermostat usually means it lost power — either the batteries died (for battery-powered models), the furnace door safety switch is disengaged, or a breaker tripped. Check and replace batteries first. If it's a hardwired thermostat, check the breaker for your air handler or furnace. A blown 3-amp fuse on the control board is another common culprit we see regularly.

Question 18

My AC hums but won't start — what's wrong?

Accepted Answer

A humming sound without the unit starting is a classic sign of a failed run capacitor or start capacitor. The capacitor gives the compressor and fan motors the electrical boost they need to start. When it fails, you'll hear the motor try to start and hum. This is one of the most common AC repairs we perform and can usually be fixed in under 30 minutes on-site.

Question 19

Why does my AC breaker keep tripping?

Accepted Answer

A repeatedly tripping breaker is a serious issue that should not be ignored — do not keep resetting it. Common causes include a grounded compressor, a short in the wiring, a locked-up condenser fan motor, or a failing capacitor pulling excess amperage. It can also be caused by a weak breaker that needs replacement. Our technician will test amperage draw and insulation resistance to find the exact cause.

Question 20

Why does my AC keep turning on and off every few minutes?

Accepted Answer

This is called short cycling, and it's hard on your compressor and drives up your electric bill. The most common causes are a dirty air filter, an oversized AC system, a failing capacitor, low refrigerant, or a thermostat in a bad location (near a supply vent or in direct sunlight). If changing the filter doesn't fix it, you need a professional diagnosis to protect your compressor from premature failure.

Question 21

My AC runs for only 5 minutes then shuts off — what's wrong?

Accepted Answer

Very short run cycles often indicate the system is overheating and tripping on a high-pressure safety switch, the compressor has an internal overload tripping, or the system is oversized for your home. An oversized AC cools the air near the thermostat quickly but never runs long enough to dehumidify or cool the whole house evenly. We'll check pressures, temperatures, and electrical readings to identify the cause.

Question 22

Is short cycling bad for my AC system?

Accepted Answer

Yes — short cycling is one of the most damaging things that can happen to your AC. Every time the compressor starts, it draws a surge of electricity and experiences mechanical stress. Frequent starts and stops dramatically shorten compressor life, increase energy consumption by 20-30%, and leave your home humid and uncomfortable. Get it diagnosed and fixed promptly.

Question 23

Why does my AC run all day and never shut off?

Accepted Answer

On extremely hot days (above 95°F), even a properly working system may run continuously and that's normal. But if your AC runs nonstop on moderate days, it usually means the system is undersized, refrigerant is low, the condenser coil is dirty and can't reject heat, or your home has significant air leaks or poor insulation. We can measure the system's capacity and compare it to your home's cooling load to determine the issue.

Question 24

My electric bill spiked — could my AC be the problem?

Accepted Answer

Absolutely. An AC that's low on refrigerant, has dirty coils, or is running with a failing compressor will consume significantly more electricity while delivering less cooling. A system that ran well last year but is suddenly costing more to operate likely has a developing mechanical or refrigerant issue. An AC tune-up can identify efficiency problems before they get worse.

Question 25

Why won't my AC shut off even after reaching the set temperature?

Accepted Answer

If the compressor keeps running after the thermostat is satisfied, a stuck contactor relay is the most likely cause — the electrical contacts weld together and keep the circuit closed. If the fan runs but the compressor shuts off, your fan setting may simply be set to 'ON' instead of 'AUTO.' A stuck contactor is a quick, affordable repair that our technicians handle routinely.

Question 26

Why is my AC making a loud banging noise?

Accepted Answer

Banging from the outdoor unit usually indicates a broken or loose compressor mount, a refrigerant line hitting the cabinet, or internal compressor damage. Banging from the indoor unit often means a loose blower wheel or a broken motor mount. Don't ignore banging — it typically gets worse and more expensive to fix the longer you wait.

Question 27

Why is my AC buzzing?

Accepted Answer

Electrical buzzing from the outdoor unit often points to a failing contactor relay, a bad capacitor, loose wiring, or a compressor that's struggling to start. A buzzing noise can also come from the reversing valve on a heat pump. Buzzing usually indicates an electrical issue that should be inspected promptly to avoid a complete breakdown.

Question 28

Why is my AC making a grinding noise?

Accepted Answer

Grinding is a metal-on-metal sound that typically means a motor bearing has failed in either the condenser fan motor (outdoor) or the blower motor (indoor). Running the system with a failed bearing will eventually seize the motor entirely, turning a $200–$400 motor replacement into a much more expensive repair. Shut the system off and call for service.

Question 29

Why is my AC squealing or screeching?

Accepted Answer

A high-pitched squeal usually comes from a blower motor belt slipping (on older belt-driven systems) or from a bearing going bad in a direct-drive motor. A screeching sound from the outdoor unit at startup can be caused by compressor pressure issues. Either way, the noise indicates something is wearing out and needs attention before it fails completely.

Question 30

Why is my AC making a clicking noise?

Accepted Answer

Clicking at startup and shutdown is normal — that's the relays and contactors engaging. Continuous or rapid clicking, however, usually indicates a failing thermostat, a defective control board, or a relay that's chattering because of a weak electrical signal. Persistent clicking with the system not starting is a classic sign of a failed capacitor or contactor.

Question 31

Why is my AC making a rattling noise?

Accepted Answer

Rattling often means something is loose — debris in the outdoor unit (sticks, leaves, or a loose fan guard), a loose panel on the cabinet, or loose ductwork. Inside, rattling can indicate a loose blower wheel. Clear any visible debris from the outdoor unit and tighten any loose panels. If the noise continues, have a technician inspect the internal components.

Question 32

Why is my AC unit vibrating and shaking?

Accepted Answer

Excessive vibration is usually caused by an unbalanced condenser fan blade, a failing compressor with worn internal mounts, or the unit sitting on an unlevel pad. Over time, vibration can loosen refrigerant connections and electrical terminals, leading to leaks and failures. We can rebalance or replace the fan blade and ensure the unit is properly supported.

Question 33

My AC is making a hissing or bubbling sound — what does that mean?

Accepted Answer

Hissing or bubbling from the refrigerant lines typically indicates a refrigerant leak. Hissing is gas escaping, and bubbling means air has entered the sealed system. A hissing sound near the indoor unit could also be a leaky duct or an expansion valve operating normally. If you suspect a refrigerant leak, call promptly — running a low system damages the compressor.

Question 34

Why does my AC smell musty or moldy?

Accepted Answer

A musty smell means mold or mildew has grown somewhere in the system — usually on the evaporator coil, in the drain pan, or inside the ductwork. Asheville's high humidity makes this especially common. We clean the coil, treat the drain pan, and can recommend UV germicidal lights that kill mold and bacteria continuously inside the system.

Question 35

Why does my AC smell like something is burning?

Accepted Answer

A burning smell can indicate an overheating motor, a wiring issue, or dust burning off the heat strips when the system first kicks on in heating mode. If the smell persists beyond the first few minutes of the season or occurs during cooling, shut the system off immediately and call us — electrical overheating is a fire risk that requires urgent attention.

Question 36

Why does my AC smell like chemicals or exhaust?

Accepted Answer

A chemical or sweet smell near the indoor unit can indicate a refrigerant leak — refrigerant has a faint ether-like odor. An exhaust-like smell may mean a motor is overheating. If you smell rotten eggs, leave the house immediately and call your gas company, as that odor is added to natural gas to warn of a leak. Never ignore unusual chemical smells from your HVAC system.

Question 37

Why is my AC blowing weak airflow from the vents?

Accepted Answer

Low airflow is most commonly caused by a dirty air filter, but it can also result from a failing blower motor, a disconnected or collapsed duct, frozen evaporator coil, or excessive duct leakage. With Asheville's older homes, we frequently find flex duct that has separated at connections or been crushed in the crawlspace. A blower door test and duct inspection can identify exactly where airflow is being lost.

Question 38

Why won't my AC compressor turn on?

Accepted Answer

The compressor not starting is usually caused by a failed capacitor, a bad contactor, a tripped high-pressure switch, or a compressor motor failure. A capacitor or contactor replacement is a straightforward, affordable repair. If the compressor motor itself has failed (grounded or open winding), you'll need to weigh compressor replacement against a full system replacement, depending on the age of your unit.

Question 39

How much does it cost to replace an AC compressor?

Accepted Answer

Compressor replacement typically ranges from $1,500 to $3,000 including parts and labor, depending on the unit size and refrigerant type. If your system uses R-22 (Freon), the compressor cost plus the expense of sourcing discontinued refrigerant often makes full system replacement the smarter choice. We'll give you honest numbers for both options.

Question 40

What is an AC capacitor and how do I know if mine is bad?

Accepted Answer

The capacitor is an electrical component that stores energy and provides the boost needed to start the compressor and fan motors. Signs of a bad capacitor include the AC humming but not starting, the fan spinning slowly, or the system shutting off shortly after starting. A swollen or leaking capacitor is visually obvious. This is one of the most common and affordable AC repairs — typically $150–$300 installed.

Question 41

How do I know if my AC has a refrigerant leak?

Accepted Answer

Common signs include the system cooling poorly, ice forming on the refrigerant lines or evaporator coil, a hissing sound near the indoor or outdoor unit, and higher-than-normal electric bills. Your AC should never need refrigerant 'topped off' — it's a sealed system. If a technician says you're low on refrigerant, you have a leak that needs to be found and repaired, not just recharged.

Question 42

Can I just add refrigerant to my AC, or does the leak need to be fixed?

Accepted Answer

Simply adding refrigerant without fixing the leak is like putting air in a flat tire without patching the hole — it's a temporary and increasingly expensive fix. EPA regulations require technicians to locate and repair refrigerant leaks. We use electronic leak detectors and nitrogen pressure testing to find leaks accurately, then make a permanent repair before recharging the system.

Question 43

Could my thermostat be causing my AC problems?

Accepted Answer

Absolutely. A malfunctioning thermostat can cause short cycling, no cooling, or the system running nonstop. Common thermostat issues include dead batteries, incorrect settings, poor placement (near heat sources or vents), and wiring problems. We always check the thermostat first during a diagnostic call — it's a quick, inexpensive fix that solves the problem more often than people expect.

Question 44

When should I replace my AC instead of repairing it?

Accepted Answer

We use the 50% rule: if the repair costs more than 50% of what a new system would cost, replacement is usually the better investment. Other strong indicators for replacement include a system older than 12-15 years, using R-22 refrigerant (which is discontinued and expensive), frequent breakdowns, and energy bills that keep climbing despite maintenance.

Question 45

How much does AC repair cost in Asheville?

Accepted Answer

Most AC repairs in the Asheville area range from $150 to $600. A diagnostic visit plus a capacitor replacement runs about $200–$350. Refrigerant leak repair with recharge runs $300–$800 depending on the leak location. Compressor replacement is $1,500–$3,000. We charge a flat diagnostic fee and always provide a written estimate before proceeding with any repair.

Question 46

Do you work on all AC brands?

Accepted Answer

Yes. Our NATE-certified technicians are trained and experienced on all major brands including Trane, Carrier, Lennox, Rheem, Goodman, American Standard, York, Amana, Daikin, Mitsubishi, and more. We stock common parts for all brands on our trucks to complete most repairs in a single visit regardless of what brand you have.

Question 47

Do you offer 24/7 emergency AC repair in Asheville?

Accepted Answer

Yes, we provide true 24/7 emergency AC repair with a real technician on call — not an answering service. When your AC fails on a 95-degree night, call (828) 845-1974 and we'll dispatch help immediately. Our emergency trucks are stocked with the most common AC components so we can resolve most emergencies the same night you call.

Question 48

What should I do if my AC breaks down during a heat wave?

Accepted Answer

First, check the breaker and thermostat settings — these fix the problem about 20% of the time. If the system is truly down, close blinds, use fans, and stay hydrated. Call us immediately for emergency service. For homes with elderly residents, young children, or anyone with health conditions, AC failure during extreme heat is a medical safety concern and we prioritize those calls.

Question 49

Why does my AC struggle more on humid days in Asheville?

Accepted Answer

Your AC has to remove moisture from the air before it can effectively cool it, and Asheville's mountain humidity creates a heavy moisture load. A system that's low on refrigerant, has a dirty evaporator coil, or is oversized will struggle especially hard on humid days because it can't properly dehumidify. If your home feels clammy even when the AC is running, call us for a system evaluation.

Question 50

How long does an AC repair usually take?

Accepted Answer

Most common AC repairs — capacitor, contactor, fan motor, or thermostat replacement — are completed in 30 minutes to 2 hours. Refrigerant leak repair and recharge may take 2-4 hours depending on the leak location. Compressor replacement is a half-day job. Because we stock common parts on our trucks, the majority of repairs are completed in a single visit without waiting for parts.

Question 51

What areas near Asheville do you serve for AC repair?

Accepted Answer

We serve all of Western North Carolina including Asheville, Hendersonville, Waynesville, Black Mountain, Weaverville, Brevard, Arden, Fletcher, Swannanoa, Mars Hill, and surrounding communities. Our service area extends roughly 45 minutes from Asheville. Same-day and emergency service is available throughout our entire coverage area.

Question 52

What's the difference between R-22 and R-410A refrigerant?

Accepted Answer

R-22 (commonly called Freon) was phased out in 2020 due to its ozone-depleting properties. R-410A is the current standard refrigerant — it's more efficient and environmentally friendly. If your system still uses R-22, refrigerant costs for repairs are extremely high ($75-$150 per pound) because no new R-22 is being manufactured. Systems using R-22 are strong candidates for replacement.

Question 53

Why is my AC unit so loud outside?

Accepted Answer

Outdoor units produce noise from the compressor and condenser fan. If the noise level has increased, it may be due to a failing compressor, loose components, a bent fan blade, or debris inside the unit. Newer systems are significantly quieter — premium models operate at 55-65 decibels compared to 75+ for older units. If noise is a concern, we can recommend ultra-quiet replacement options.

Question 54

How do I reset my AC unit?

Accepted Answer

To reset your AC, turn the thermostat to 'off,' then flip the breaker for both the indoor and outdoor units off. Wait a full 5 minutes (this is important — the compressor needs time to equalize pressures). Turn the breakers back on, then set the thermostat to 'cool' with the temperature 5 degrees below room temperature. If the system doesn't restart normally, call us for a diagnosis.

Question 55

Why is my thermostat not reaching the set temperature?

Accepted Answer

When your thermostat reads a lower (or higher) temperature than what you've set, the problem is usually not the thermostat itself — it's the HVAC system struggling to keep up. Dirty filters, low refrigerant, duct leaks, or an undersized system are the most common culprits in Western NC homes. However, if the thermostat is mounted near a window, exterior wall, or supply vent, it can get a false reading and shut the system off too early.

Question 56

What causes my HVAC system to short cycle on and off?

Accepted Answer

Short cycling — where the system runs for just a few minutes before shutting off — is usually caused by an oversized system, a dirty filter, a failing compressor, or a thermostat in a bad location that's getting false temperature readings. In our experience across Asheville-area homes, oversized equipment is the number one cause because installers often size by square footage alone without doing a proper Manual J load calculation.

Question 57

Is R-22 Freon still available? How much does it cost?

Accepted Answer

R-22 is still available from reclaimed and stockpiled supplies, but the price has skyrocketed — expect $150–250 per pound or more, meaning a full recharge can cost $600–1,500+. By comparison, R-410A runs about $50–75 per pound. If your R-22 system needs a major refrigerant charge, it's usually more cost-effective to replace the entire system with a modern R-410A or R-454B unit.

Question 58

When was R-22 Freon phased out?

Accepted Answer

The production and import of R-22 was completely banned in the United States on January 1, 2020 under the Clean Air Act. Existing R-22 systems can still be serviced using reclaimed or stockpiled refrigerant, but the supply is shrinking every year and prices keep climbing. If you're still running an R-22 system here in WNC, we strongly recommend planning a replacement sooner rather than later.

Question 59

Should I replace my R-22 AC system or just keep recharging it?

Accepted Answer

If your R-22 system only has a minor leak and is otherwise in good condition, a recharge plus leak repair might buy you a year or two. But if it's over 15 years old or needs a major repair, replacement is the smarter investment — you'll get a more efficient system, lower operating costs, and avoid the escalating R-22 prices. Most of our customers in the Asheville area save enough on energy bills to offset a significant portion of the replacement cost within 5–7 years.

Question 60

What are the signs of a refrigerant leak in my AC?

Accepted Answer

Common signs include the system blowing warm air, ice forming on the evaporator coil or refrigerant lines, a hissing or bubbling sound near the indoor or outdoor unit, and higher-than-normal electric bills from the compressor working overtime. In severe cases, you'll notice the system running constantly without reaching the set temperature. We use electronic leak detectors and UV dye to pinpoint the exact location of the leak.

Question 61

How are refrigerant leaks repaired?

Accepted Answer

The repair depends on where the leak is. Leaks at service valves, flare fittings, or solder joints can usually be sealed or re-soldered — that's a straightforward repair. Leaks in the evaporator coil or condenser coil are more serious and often require replacing the entire coil. We always locate and fix the leak before recharging — just topping off refrigerant without fixing the leak is throwing money away.

Question 62

Can I switch my AC from R-22 to R-410A refrigerant?

Accepted Answer

You cannot simply swap refrigerants — R-410A operates at nearly 60% higher pressure than R-22, and the compressor, coil, and line set in an R-22 system aren't designed to handle that. There are some R-22 'drop-in' replacements (like R-407C or MO99) that can work in existing equipment with modifications, but performance is never as good as a purpose-built system. In most cases, full system replacement is the right call.

Question 63

What's the difference between topping off refrigerant and a full recharge?

Accepted Answer

Topping off means adding a small amount of refrigerant to bring the system back to its rated charge — this only makes sense if the leak is small and has been repaired. A full recharge means recovering whatever refrigerant is left, repairing the leak, pulling a vacuum on the system, and charging it to the manufacturer's exact specification. A full recharge is the proper procedure and ensures the system runs at peak efficiency.

Question 64

Why does my AC need refrigerant in the first place?

Accepted Answer

Refrigerant is the lifeblood of your AC — it absorbs heat from the indoor air and releases it outside. Without the correct charge, the system can't transfer heat efficiently, leading to poor cooling, higher bills, and eventual compressor failure. A properly installed AC system should never need refrigerant added unless there's a leak — it's a sealed system, not something that gets 'used up' like fuel.
