Question 1

Should I replace my furnace or switch to a heat pump?

Accepted Answer

It depends on your home, fuel availability, and budget. Heat pumps are more efficient in mild climates but may need supplemental heat in extreme cold. We'll help you evaluate both options.

Question 2

How long does a new furnace last?

Accepted Answer

A well-maintained furnace typically lasts 15-20 years. High-efficiency models may last even longer with regular maintenance.

Question 3

What efficiency rating should I look for?

Accepted Answer

We recommend 95% AFUE or higher for gas furnaces. Higher efficiency means lower fuel bills and a smaller carbon footprint.

Question 4

Should I upgrade to a smart thermostat with my furnace?

Accepted Answer

A smart thermostat like an Ecobee or Google Nest can save 10–15% on heating costs through learning schedules, geofencing, and optimized cycling. However, not every furnace is compatible — older systems without a C-wire may need an adapter. We install and configure smart thermostats as part of our services and ensure they communicate properly with your specific furnace model.

Question 5

What size furnace do I need for my home?

Accepted Answer

Furnace size depends on your home's square footage, insulation levels, window area, ceiling height, and local climate — not just square footage alone. In Asheville's climate zone 4A, most homes need 35–50 BTUs per square foot. A 2,000 sq ft home typically needs a 70,000–100,000 BTU furnace. We perform a Manual J load calculation for every installation to determine the exact right size — oversizing causes short cycling and comfort problems, undersizing means the house never gets warm enough.

Question 6

What furnace brands does Quality Mechanical install?

Accepted Answer

We install and service all major furnace brands including Goodman, Trane, Carrier, Lennox, Rheem, American Standard, Amana, and York. We're particularly experienced with Goodman systems, which offer excellent reliability at a competitive price point. Regardless of brand, proper sizing and installation quality matter more than the name on the unit — a perfectly installed mid-range furnace outperforms a poorly installed premium one every time.

Question 7

Is a gas furnace or heat pump better for Asheville?

Accepted Answer

For most Asheville homes, a dual-fuel system — a heat pump with a gas furnace backup — is the ideal setup. The heat pump handles heating efficiently down to about 35–40 degrees, and the gas furnace takes over when temperatures drop below that. This gives you the efficiency of a heat pump for 70% of the winter and the reliable power of gas for the coldest nights. We can evaluate your home and recommend the best configuration.

Question 8

Should I switch from an electric furnace to a gas furnace?

Accepted Answer

If natural gas is available at your home, switching from electric resistance heating to a gas furnace can cut your winter heating bills by 50–60%. The installation involves running a gas line (if not already present), installing the furnace, and modifying the venting. The investment typically pays for itself within 3–5 years through energy savings. If gas isn't available, a heat pump is the most efficient electric alternative.

Question 9

Do I need new ductwork with a new furnace?

Accepted Answer

Not always, but it should be evaluated. If your existing ductwork is properly sized, sealed, and in good condition, it can be reused. However, if the ducts are undersized for the new furnace's airflow requirements, severely deteriorated, or full of leaks, installing a high-efficiency furnace on bad ductwork is like putting a sports car engine in a car with flat tires. We inspect ductwork during every installation estimate.

Question 10

How long does it take to install a new furnace?

Accepted Answer

A standard furnace replacement — swapping the old unit for a new one using existing ductwork and gas lines — takes 4–8 hours and is completed in a single day. If we need to run new gas lines, modify ductwork, add a new flue, or convert from electric to gas, it may take a full day or extend into a second day. We'll give you a clear timeline before work begins.
