This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Types of Air Conditioners

There are a few different varieties of air conditioners on the Chattanooga market. While HVAC professionals can work with most types, knowing which one you have will streamline your company search.

  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
  • Central AC: These are the most common home air conditioners, offering precise, consistent temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to different rooms in your home.
  • Portable air conditioners: As the name hints, portable ACs don't require permanent installation or ductwork. Instead, they remove hot air through an exhaust hose connected to a window or nearby vent. They're popular for condos, apartments, or individual rooms.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Chattanooga apartments, condos, and townhomes. These compact, affordable units are designed for cooling single rooms and small spaces, and they fit snugly in a window frame or dedicated wall slot. Many window-mounted AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Chattanooga AC Repair Service

With Chattanooga's extreme heat, AC problems are urgent to fix for your safety and comfort. However, don't race to sign a contract until you're convinced a company is the best fit for you. We recommend following these steps in your research. While you might want to resolve your AC issue quickly, you should carefully investigate what's out there before committing to a repair service. Take the following steps to ensure you find the right company for your home.

Confirm the Company Is Properly Licensed and Insured

In Tennessee, licensed prime contractors can perform HVAC jobs valued at $25,000 or more. For projects less than $25,000, a company will usually need a Limited Licensed Electrician credential. They also need to subcontract electrical work and permit-pulling to a licensed electrician.

Many states and cities also require companies to carry liability insurance. Even if your community doesn't require it, we still recommend choosing an insured company. This will protect you if an accident happens or something gets damaged.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that handle complaints effectively and honor their warranties.

It's normal for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a business if most reviewers had subpar experiences.

Compare Estimates

Obtain at least three detailed, written estimates from different companies for the best value. A good estimate should include additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.

Frequently Asked Questions About AC Repair in Chattanooga

How much can I expect to pay for AC repair in Chattanooga?

Your AC repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$73–$177
Electrical circuits$98–$147
Drainage problems$98–$147
Frozen condenser coils$246–$986
Fan or air blower issues$443–$640
Compressor replacement$591–$1183

Does my air conditioner need routine maintenance? If so, how often?

It's a good idea to service your AC at least once a year. You can further maximize its lifespan and efficiency by keeping the outdoor unit clear of brush and debris.

What do I do if my AC is running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan pulls air into the outdoor unit through the condenser coil to remove heat energy from your home. A technician can help by clearing the clog or replacing a faulty coil.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely position a window AC unit by yourself. However, installing other AC units should almost always be done by an HVAC contractor who knows the complicated tubing, wiring and piping. We also advise opting for professional installation due to the potential hazard of refrigerant spills.

My HVAC problem is urgent. How quickly could a company respond?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. Some companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the company directly is best so you can get the most accurate information.
