Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner types, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC models.

  • Window-mounted ACs: Window air conditioners are a popular choice for Knoxville condos, townhomes, and apartments. These compact, affordable units are designed for cooling small spaces and single rooms, 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.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They provide quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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 a common choice for condos, apartments, or individual rooms.
  • 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 various rooms in your home.

How to Choose Your Knoxville AC Repair Service

With the intense Knoxville heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to investigate different HVAC companies first. We recommend adhering to these steps as you prepare.

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.

You should also check a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if something gets damaged during work.

Read Customer Reviews

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

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

Compare Estimates

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

Frequently Asked Questions About AC Repair in Knoxville

What's the cost of an AC repair job in Knoxville?

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$61–$163
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$82–$204
Refrigerant leak$400–$1500
Frozen condenser coils$1,225–$3,674
Fan or air blower issues$150–$200
Compressor replacement$600–$1,551

What are some signs that I should call an HVAC repair company?

Here are a few of the frequent AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

When is the best time to replace an AC unit?

The best time to replace HVAC systems is during the off-season, when there's less demand for HVAC technicians and costs are cheaper. With Knoxville's hot average highs, the off season will usually be in the winter months when temperatures start to drop.

Why is my AC running but not cooling?

If your air conditioner is running but not cooling, a technician will usually check the condenser coil first. Normally, the outdoor unit fans draw air into the coil so the system can extract heat energy from your home. Clearing the blockage might be all that's necessary to get your AC cooling again.

How quickly can an HVAC company in Knoxville respond to emergency repair requests?

Some repair companies offer same-day or next-day service for emergency air conditioner breakdowns. However, the specific timeframe will vary depending on the team's schedule, the terms in your contract, and the severity of the issue. For the most accurate info, we recommend contacting the contractor directly and explaining the situation.
