Common Types of Air Conditioners

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

  • Ductless mini-split: Ductless mini-split air conditioner systems have an outdoor unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Window ACs: Window air conditioners are a popular choice for Joliet apartments, townhomes, and condos. 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-mounted AC users deploy 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.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name hints, portable AC 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 a common choice for condos, apartments, or individual rooms.

How to Choose Your Joliet AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before hiring 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

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

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that respond to complaints effectively 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 business if most reviewers had subpar experiences.

Compare Estimates

We recommend getting at least three different estimates to find the best cost and services. Get a written copy of each quote, and learn more about permitting fees, installer guarantees, emergency repair availability and manufacturer warranties.

Frequently Asked Questions About AC Repair in Joliet

What's the cost of an AC repair job in Joliet?

Your AC unit repair costs will hinge on the type of unit you have and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like changing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$63–$169
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,269–$3,807
Fan or air blower issues$150–$200
Compressor replacement$600–$1,607

How often should Joliet homeowners have their AC systems serviced?

Homeowners should have their AC systems serviced annually 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 do I do if my AC is 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 remove heat energy from your home. A technician can help by clearing the clog or replacing a damaged coil.

What industry certifications should I look for when researching Joliet AC repair companies?

Private accreditations might not be required, but businesses that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).

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

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. Some companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the company directly is best so you can get the most accurate information.
