Common Types of Air Conditioners
There are a few different varieties of HVAC systems on the Johnson City market. While HVAC contractors can work with most types, knowing which one you have will ease your company hunt.
- Split ACs: Split AC units have two main elements: one indoors and one outdoors. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- Ductless mini-split: Ductless mini-split AC units have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
- Portable air conditioners: As the name implies, portable air conditioners 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 apartments, condos, or individual rooms.
- 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.
- Window ACs: Window air conditioners are a popular choice for Johnson City 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.
How to Choose Your Johnson City AC Repair Service
While you might want to resolve your AC issue quickly, you should do some essential research before signing a contract with a repair service. Take the following steps to ensure you find the best 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 recognizes businesses that respond to complaints professionally and honor their warranties.
It's normal for even the best AC repair companies to have both positive and negative reviews. Read each one carefully, and avoid a company if most reviewers had subpar experiences.
Compare Estimates
Obtain at least three detailed, written estimates from different providers for the best deal. A good estimate should consider additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.
