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.
