Chattanooga HVAC Repair, Installation & Maintenance
When you need a dependable heating and cooling company in Chattanooga, Franklin HVAC is the company to call. We've been keeping local homes and businesses comfortable through every season, building our reputation one satisfied neighbor at a time. Our technicians are local, not dispatched from across the state, which means shorter waits and a real understanding of the climate patterns, housing stock, and ductwork quirks that shape how HVAC systems here perform and fail.
From a single no-cool emergency to complete system replacements, ductless mini-split installations, and seasonal maintenance programs, our team takes on every type of residential and commercial heating and cooling need. We offer prompt service and give you upfront pricing before any work begins, no hidden fees, ever. Our trucks are stocked with the parts that fail most, capacitors, contactors, igniters, flame sensors, blower motors, and thermostats, so most repairs are finished in a single visit.
Whether your air conditioner is running nonstop without cooling, your furnace is short-cycling, or you're simply planning ahead for a system past its prime, one call to (615) 537-0369 gets a skilled local technician headed your way with everything needed to restore your comfort the same day whenever possible.

Complete Heating & Cooling Services for Chattanooga Properties
Heating and cooling around here means a wide mix of equipment: aging furnaces on the older streets, high-efficiency heat pumps in recent construction, ductless mini-splits in additions and converted garages, and packaged units on commercial buildings. Our team works on every one of those systems. Our technicians have years in the field, and we've learned how the weather here, the age of local homes, and local code affect the way equipment runs and fails.
On the residential side, we take care of everything from quick fixes, like a weak capacitor, a burned contactor, a dirty flame sensor, or a seized blower motor, to tracking down refrigerant leaks, complete system replacements, and ductless additions. Every new system we install is sized with a proper load calculation instead of a rule of thumb, so you get even temperatures and sensible utility bills instead of a unit that short-cycles itself to an early death. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.
Commercial service makes up a large share of our work too. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurants, retail stores, offices, and multi-unit properties, and we know that every hour of downtime costs your bottom line. To keep that downtime short, we keep common commercial parts stocked, diagnose quickly, and schedule repairs around your operating hours whenever possible.
Quick Heating and Cooling Help in Chattanooga
Call us with a problem and a real person picks up, not a recording. The majority of calls are scheduled within a day, and urgent calls, a dead air conditioner during a heat wave or a furnace that fails on a bitter night, jump to the top of the schedule. Scheduling stays flexible so nobody is left waiting for a callback.
These are the problems that come up most when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that ignites and shuts off, a breaker that trips every time the system kicks on, an evaporator coil that has frozen, a condensate drain backed up into the furnace cabinet, or a thermostat that has gone blank. Most of them trace back to parts already on our trucks: capacitors, contactors, igniters, flame sensors, universal control boards, and common fittings. You'll see the price up front, and that's the price you pay.
If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (615) 537-0369. A few minutes of caution can prevent a much larger repair.
Keeping Your Chattanooga HVAC System Running Longer
Many mid-season breakdowns start with skipped maintenance, and the habits that prevent them are simple. Swap your filter every one to three months, keep plants and shrubs at least two feet from the outdoor condenser, and rinse the condenser coil once a year in spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.
Take a look at the age of your system. Its age tells you a lot. Most well-maintained air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that range and also shows rising bills, uneven temperatures, or repeated repairs, it's usually due for a planned replacement, and that's almost always cheaper and easier on everyone than an emergency replacement when the first heat wave hits.
Minor issues rarely stay small when they're ignored. Consider a weak capacitor: replacing it is a quick, inexpensive repair, but if it's ignored for a season, it can burn out the compressor, and suddenly a minor fix becomes a full system replacement. That's why we ask homeowners to keep our number in their phone and call at the first sign of trouble. Catching it early saves money and spares you a few miserable nights.
Comfort Challenges Chattanooga Homeowners Face
The service calls we run around here tend to follow the calendar. In summer it's air conditioners humming but not cooling, weak capacitors that finally quit on the first hot week, and condensate drains backing up into the furnace cabinet. In winter it's furnaces that light and shut back down, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see thermostats misreading rooms, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. All of them start small, and all of them cost less to fix early. If your system is acting up, call (615) 537-0369 before the season turns it into an emergency.
