Common Types of Air Conditioners

By understanding which type of air conditionerunit you have, you'll feel more confident in your contractor search. Caseyville HVAC technicians have experience with different AC makes and models, and they can adapt their skills to your needs.

  • Ductless mini-split: Ductless mini-split AC systems have an outdoor unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
  • Split ACs: Split AC systems have two main elements: one inside and one outside. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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 different rooms in your home.
  • Portable air conditioners: As the name implies, portable AC systems 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.
  • Window-mounted ACs: Window air conditioners are a popular choice for Caseyville condos, townhomes, and apartments. These budget-friendly, convenient 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.

How to Choose Your Caseyville AC Repair Service

With the intense Caseyville heat, AC issues are top priority 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

There's no state HVAC license in the Land of Lincoln. Instead, cities and counties are free to set their own regulations and requirements. Contact your local authorities 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 something gets damaged 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 resolve complaints professionally 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 provider if most reviewers had subpar experiences.

Compare Estimates

Obtain at least three detailed, written estimates from different companies for the best deal. A good estimate should factor in additional fees such as permitting costs. You should also ask about manufacturer warranties, installer guarantees, and the emergency repair process.
