Common Types of Air Conditioners
HVAC technicians have the expertise to service most air conditioner models, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC types.
- Split ACs: Split air conditioner units have two main elements: one inside and one outside. They provide quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- Ductless mini-split: Ductless mini-split air conditioners have an exterior unit and multiple interior units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
- Central AC: These are the most common home air conditioners, 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 St. Louis condos, townhomes, and apartments. These budget-friendly, convenient units are designed for cooling single rooms and small spaces, and they fit snugly in a window frame or dedicated wall slot. Many window AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
- Portable air conditioners: As the name suggests, portable air conditioner units 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.
How to Choose Your St. Louis AC Repair Service
You likely want a swift resolution for your air conditioner's problem. However, before engaging with 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
While Missouri licenses some contractors at the state level, it does not for HVAC companies. Local governments can set their own requirements, and we recommend contacting your town hall or county building department for more information.
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 accidents happen during work.
Read Customer Reviews
Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that handle complaints professionally and honor their warranties.
It's normal for even the best AC repair businesses 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 deal. A good estimate should list additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.
