Common Types of Air Conditioners

By understanding which type of air conditioner you have, you'll feel more confident in your company search. Du Page HVAC professionals have experience with different AC makes and models, and they can adapt their skills to your needs.

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

How to Choose Your Du Page AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before committing to a repair service. Take the following steps to ensure you find the right 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. Check with your local building department for more information.

You should also verify 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 businesses that resolve complaints effectively 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 company if most reviewers had subpar experiences.

Compare Estimates

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

What are some signs that I should call an HVAC repair company?

Here are several of the most common AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

Does my air conditioner need routine maintenance? If so, how often?

Homeowners should have their AC systems serviced once a year to ensure optimal performance. This usually involves cleaning the outdoor unit of brush and debris. Regular servicing can help to maintain the system's efficiency and prolong its lifespan.

Why is my AC running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan pulls air into the outdoor unit through the condenser coil to extract heat energy from your home. A technician can help by clearing the clog or replacing a faulty coil.

How quickly can an HVAC company in Du Page respond to emergency repair requests?

Some repair companies offer same-day or next-day service for emergency air conditioner breakdowns. However, the specific timeframe will vary depending on the team's schedule, the terms in your contract, and the severity of the issue. For the most accurate info, we recommend contacting the contractor directly and explaining the situation.
