Common Types of Air Conditioners

By knowing which type of air conditionersystem you have, you'll feel more empowered in your company search. Normal HVAC contractors have experience with different AC makes and models, and they can customize 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 higher energy efficiency, individual room temperature control, and flexible installation options.
  • Central AC: These are the most common home air conditioners, offering consistent, precise 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.
  • Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They offer silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Normal townhomes, apartments, and condos. 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 air conditioner 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 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 Normal AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before recruiting a repair company, it's important to carefully investigate how well it fits your home's needs. Here are a few essential steps to follow.

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.

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

Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits businesses that respond to complaints professionally and honor their warranties.

It's normal for even the best AC repair providers 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 value. A good estimate should factor in additional fees such as permitting costs. You should also ask about the emergency repair process, installer guarantees, and manufacturer warranties.

Frequently Asked Questions About AC Repair in Normal

How much can I expect to pay for AC repair in Normal?

Your AC unit repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$61–$162
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,217–$3,651
Fan or air blower issues$150–$200
Compressor replacement$600–$1,542

How often should Normal homeowners have their AC systems serviced?

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.

What month is best for getting an air conditioner replaced?

To find the best time for your installation, consider both Normal's temperatures and company demand. Generally, contractors are busier as the climate warms up and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

Why is my AC running but not cooling?

If your air conditioner is running but not cooling, a technician will usually check the condenser coil first. Normally, the outdoor unit fans draw air into the coil so the system can extract heat energy from your home. Removing the obstruction might be all that's necessary to get your AC back on track.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

Yes, it's better to get a new air conditioner professionally installed. Most units have complicated piping and wiring that can confuse even an experienced do-it-yourselfer. They also use refrigerants that could pose health hazards if they spill or leak. With their training and equipment, the right technician will set you up for success.
