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

By knowing which type of air conditioner you have, you'll feel more empowered in your company search. Gallatin HVAC technicians have experience with different AC makes and models, and they can tailor their skills to your needs.

  • Window ACs: Window air conditioners are a popular choice for Gallatin apartments, townhomes, and condos. 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-splits have an outdoor unit and one or more indoor 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 residential AC systems, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
  • Portable air conditioners: As the name implies, 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 preferred for condos, apartments, or individual rooms.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Gallatin AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before recruiting a repair company, it's important to do careful research to ensure it's the best for your home. Here are a few essential steps to follow.

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

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

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

Compare Estimates

We recommend getting three or more estimates to find the best value. Get a written copy of each quote, and learn more about installer guarantees, manufacturer warranties, permitting fees and emergency repair availability.

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

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

Is hiring an HVAC company better than doing the repair on my own?

Yes, it's better to get a new air conditioner professionally installed. Most units use complex wiring and piping that can confuse even a seasoned do-it-yourselfer. They also use chemical coolants that could pose health hazards if they spill or leak. With their training and equipment, the right technician will set you up for success.

How many years until I should replace my AC unit?

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.

How quickly can an HVAC company in Gallatin 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 company directly and explaining the situation.
