Quality Mechanical installs, repairs, and services the complete Lennox furnace lineup across Asheville and surrounding communities.
Lennox Furnace Installation
Lennox's gas furnace range runs from the reliable Merit series (80% AFUE) through the Signature Collection, crowned by the SLP99V — a variable-speed, modulating furnace that achieves up to 99% AFUE with sound levels as low as 41 decibels. The Dave Lennox Signature Collection modulating gas valve adjusts in 0.5% increments for extraordinarily precise temperature control. Quality Mechanical runs a Manual J load calculation for each furnace installation and verifies proper venting, gas connections, and duct sealing.
Lennox Furnace Repair
Our technicians handle every Lennox furnace model, from legacy systems to current iComfort-enabled units. Common repairs include SureLight ignition system issues, flame sensor service, inducer motor replacement, gas valve diagnostics, blower motor faults, and iComfort control troubleshooting. We stock common Lennox parts for quicker furnace repair service.
Lennox Warranty Coverage
Most Lennox furnaces carry a limited lifetime heat exchanger warranty plus a 10-year limited parts warranty when registered. Select Signature Collection models include enhanced warranty terms. Quality Mechanical manages registration and warranty support from day one.
Is Lennox Right for Your Home?
Lennox furnaces represent the gold standard in quiet, efficient heating. The SLP99V at 99% AFUE wastes virtually no energy, and at 41 decibels you will barely notice it running. If whisper-quiet operation and maximum fuel efficiency matter to you, Lennox is the benchmark. Compare in our Lennox vs. Trane guide.
HVAC Challenges in Marion
At just 1,437 feet, Marion sits at one of the lowest elevations in our service area — meaning hotter summers and higher cooling demands than mountain communities to the west. The Catawba Valley funnels warm air from the piedmont, and Marion homes typically need 15–20% more cooling capacity than comparable Asheville homes. However, milder winters mean heat pump systems perform exceptionally well here year-round.
Seasonal Tip for Marion Homeowners
Marion's lower elevation means summer arrives 2–3 weeks earlier than in Asheville. Schedule your AC maintenance in early April to beat the rush, and consider upgrading to a higher-SEER unit if you're replacing — the longer cooling season means energy savings add up faster here.
