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 describe each of the common AC models.

  • Window ACs: Window air conditioners are a popular choice for Collinsville condos, townhomes, and apartments. 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 air conditioner users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split AC systems have an outdoor unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • 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.
  • Split ACs: Split air conditioners have two main elements: one inside and one outside. They provide silent operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name suggests, 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 condos, apartments, or individual rooms.

How to Choose Your Collinsville AC Repair Service

While you might want to resolve your AC issue quickly, you should carefully investigate what's out there before signing a contract with a repair service. Take the following steps to ensure you find the most suitable company for your home.

Confirm the Company Is Properly Licensed and Insured

There's no state HVAC license in the Land of Lincoln. Instead, cities and counties are free to set their own requirements and regulations. Consult your local building department for more information.

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 accredits contractors that resolve complaints effectively and honor their warranties.

It's common for even the best AC repair businesses 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 at least three different quotes to find the best value. Get a written copy of each quote, and learn more about permitting fees, manufacturer warranties, emergency repair availability and installer guarantees.
