Common Types of Air Conditioners

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

  • Split ACs: Split ACs have two main elements: one inside and one outside. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name suggests, 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 apartments, condos, or individual rooms.
  • Window ACs: Window air conditioners are a popular choice for Chattanooga townhomes, apartments, and condos. These budget-friendly, convenient 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Central AC: These are the most common home air conditioners, offering consistent, precise 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.
  • 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.

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 rush to sign a contract until you're sure a company is the best fit for you. We recommend following these steps in your research.

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 confirm 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

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

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

Compare Estimates

We advise getting contacting at least three different companies to find the best pricing and offerings. Get a written copy of each quote, and learn more about permitting fees, emergency repair availability, installer guarantees and manufacturer warranties.

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 the type of unit you have 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$63–$167
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,255–$3,764
Fan or air blower issues$150–$200
Compressor replacement$600–$1,589

When is the best time to replace an AC unit?

To discover the best time for your installation, consider both local weather patterns and company demand. Generally, contractors are busier as the weather warms up and less busy during cool seasons. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

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 draws 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 defective coil.

How long is my air conditioner's lifespan? When should I consider a replacement?

You won’t need to change air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become hard to find. You'll probably need to consider new AC installation if your company can't replace a broken part.

Should my HVAC company have a private accreditation?

Private accreditations might not be required, but contractors that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).
