AfterFast, Reliable AC Installation Across Farragut
A new AC installation in Farragut typically runs $3,500-$7,500 for most homes, and every job starts with a written fixed price before any equipment is ordered. We’re Coldharbour Heating & Air, and our AC Installation team has spent years working in the planned subdivisions off Northshore Drive, Concord Road, and Kingston Pike - the neighborhoods where all-electric heat pumps installed during the 1980s through mid-2000s are now hitting their replacement ceiling all at once. Dispatch and scheduling are coordinated from our Memphis office, but our crews live and work in the Farragut area, which means we understand why a standard replacement spec sheet from a national chain won’t cut it here. Call (817) 402-2972 for a free estimate with a written price that won’t change.
Why Coldharbour Heating & Air Is Farragut’s Preferred AC Installation Company
We’ve been serving Farragut since 2003 as part of the Kingswell network of independently owned HVAC businesses, and our reputation here is built on showing up in the window we promised and leaving the guarantee in writing. Homeowners in neighborhoods like Choto Hills, Fox Run, and the Concord Road corridor tell us the same story: the last company gave a verbal ballpark, then handed them a bill 40% higher at the door. That doesn’t happen with us. Our written price arrives before a single tool comes out, and it’s backed by The Kingswell Way - say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails. Our 365-Day Done Right Promise means if any repair fails within a full year, we return and correct it at no charge. Phones are answered by a live person 24 hours a day, 7 days a week, and our technicians are background-checked, uniformed, and trained on nine major brands including Trane, Lennox, Goodman, and Rheem.
Furnace Installation in Farragut
Furnace Installation in Farragut is a different conversation than it is in older Knoxville neighborhoods, because a large share of our local housing stock was built during TVA’s aggressive “all-electric home” push with no gas infrastructure at all. When we do install a gas furnace here, it’s usually part of a dual-fuel conversion - pairing a high-efficiency gas furnace with a heat pump so the furnace handles the coldest days below the heat pump’s balance point, while the heat pump carries the load the rest of the year. Most furnace installations in Farragut run $3,500-$7,500 when bundled with compatible cooling equipment, though standalone furnace swaps in homes that already have gas lines are less common here.
When Dual-Fuel Makes Sense
If your all-electric subdivision home has had gas service extended to the property since original construction, a dual-fuel system can eliminate those January emergency heat-strip calls that every Farragut homeowner knows. We size the gas furnace to cover the full heating load below 35°F, then let the heat pump handle efficient heating above that threshold.
Electric-Only Conversions
For homes without gas access, we install high-HSPF heat pumps with properly sized auxiliary heat strips - not the rule-of-thumb sizing that leaves you cold during polar vortex events, but strips sized from a real Manual J load calculation that accounts for your home’s actual envelope and Farragut’s winter design temperatures.
HVAC Installation in Farragut
HVAC Installation in Farragut means designing around homes that are bigger, more complex, and more demanding than the regional average. We’re talking about 2,800-5,000 square foot two-story builds with vaulted great rooms, open floor plans, and finished basements - the kind of spaces where a single-zone system will always leave the upstairs 4-6 degrees warmer than the main floor, no matter how many times you adjust the thermostat. Most complete HVAC installations in Farragut fall in that $3,500-$7,500 range for standard equipment, with multi-zone and variable-capacity systems at the higher end.
Multi-Zone Design for Two-Story Homes
Thermal stratification isn’t a mystery; it’s physics. Hot air rises, and a single thermostat on the main floor has no idea the upstairs is sweltering. We design dual-zone systems with independent dampers and separate thermostats so each level gets the airflow it actually needs, not whatever happens to drift up the stairwell.
Commissioning That Delivers the Rated Efficiency
A system is only as good as its commissioning. We measure static pressure, verify airflow per ton, and calibrate thermostat sensors against actual room temperatures. Without this step, that 18 SEER2 rating on the label is just a number - the real-world efficiency will be lower, and your bills will prove it.
Trusted Brands We Service in Farragut
Our technicians are trained to service and install nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Farragut customers, we keep common Trane and Lennox heat pump components stocked locally, which means faster turnaround when a compressor or reversing valve fails during a July heat wave or a January cold snap. We also work with Goodman and Rheem systems, which are common in the original equipment installed during Farragut’s 1990s building boom. Every installation uses factory-authorized parts and follows manufacturer commissioning procedures - no shortcuts that void your warranty.
Common AC Installation Problems We See in Farragut Homes
- Single-zone systems in oversized two-story plans. A 4,200 square foot home with a vaulted great room and finished basement cannot be served by one thermostat and one air handler. The upstairs bedrooms run hot, the basement runs cold, and the system never cycles off because it’s chasing an impossible average.
- Heat strips sized by tonnage rule-of-thumb instead of Manual J. When January polar vortex air funnels through the Tennessee Valley ridges, heat pumps drop below their efficient operating range. Undersized strips can’t carry the load, and we get the emergency call at 6 a.m. when the house is 58 degrees.
- Equipment sized for sensible load only in Choto-area lakeside homes. Fort Loudoun Lake keeps local humidity 5-8 points above the rest of Farragut. A system sized only for temperature will satisfy the thermostat while indoor relative humidity climbs past 60%, creating mold-friendly conditions and that clammy feeling no homeowner wants.
- Skipped commissioning on replacement jobs. The old system is out, the new system is in, but nobody measured airflow, checked charge by subcooling, or verified thermostat calibration. The homeowner gets a new box that performs like an old box, and the efficiency rating on the label is fiction.

FAQs About AC Installation in Farragut
You can only add a gas furnace if natural gas service has been extended to your property since original construction, which is uncommon in Farragut’s 1980s-2000s all-electric subdivisions. Most homeowners in this situation are better served by a high-HSPF heat pump with properly sized auxiliary heat strips, or by planning for a dual-fuel conversion if gas becomes available. Call (817) 402-2972 and we’ll check your utility situation during the free estimate.
Because a single-zone system in a 2,800-5,000 square foot two-story home with a vaulted great room is physically incapable of delivering balanced temperatures. The fix is a dual-zone design with independent dampers, separate thermostats, and airflow balancing during commissioning - not a bigger unit, which would just short-cycle and waste energy. We see this exact problem in Fox Run, Choto Hills, and Concord Road-area homes regularly.
Yes. Lake evaporation keeps Choto-area humidity 5-8 points higher than the rest of Farragut, which means latent load - moisture removal - is just as important as temperature drop. We routinely recommend two-stage or variable-capacity cooling with a dedicated whole-home dehumidifier tap, and we size equipment to handle both sensible and latent loads, not just the thermostat number.
The SEER2 rating assumes proper airflow, correct refrigerant charge, and matched indoor and outdoor components verified during commissioning. We measure static pressure, set blower speed to manufacturer spec, weigh in charge by subcooling, and document actual supply and return temperatures. Without this step, a “18 SEER2” system can perform like a 13 SEER2 system, and your utility bills will show it.
Most Farragut AC installations run $3,500-$7,500. The lower end covers single-stage equipment replacement in homes with compatible ductwork and electrical service. The upper end reflects multi-zone modifications, variable-capacity Trane or Lennox systems, whole-home dehumidifiers for lake-area humidity, and electrical upgrades. Every estimate is free and every price is fixed in writing before work begins - call (817) 402-2972 to schedule yours.
