Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner types, but knowing more about what you have can be beneficial. Below, we'll describe each of the common AC types.

  • Split ACs: Split AC units have two main elements: one inside and one outside. They offer quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name implies, portable air conditioner 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.
  • Central AC: These are the most common home air conditioners, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
  • Ductless mini-split: Ductless mini-split air conditioners have an outdoor unit and multiple interior units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
  • Window ACs: Window air conditioners are a popular choice for Antioch townhomes, condos, and apartments. 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.

How to Choose Your Antioch AC Repair Service

With Antioch's intense heat, AC problems are urgent to fix for your safety and comfort. However, don't race to sign a contract until you're convinced a company is the best fit for you. We recommend following these steps in your research.

Confirm the Company Is Properly Licensed and Insured

California HVAC contractors need a C-20 (Warm-Air Heating, Ventilation, and Air-Conditioning) license from the Department of Consumer Affairs. The application process involves comprehensive exams on business law and practical skills.

You should also verify a company has sufficient liability 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 recognizes contractors that resolve 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 company if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Antioch

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

Your AC system 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$66–$177
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,328–$3,985
Fan or air blower issues$150–$200
Compressor replacement$600–$1,683

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

Here are some 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.

How often should Antioch homeowners have their AC systems serviced?

It's a good idea to service your AC at least annually. You can further maximize its lifespan and efficiency by keeping the outdoor unit clear of brush and debris.

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 extract heat energy from your home. A technician can help by clearing the clog or replacing a damaged coil.

Is hiring an HVAC company better than doing the repair on my own?

You can most likely set up a window AC unit by yourself. However, installing other AC units should almost always be done by an HVAC contractor who knows the complex piping, wiring and tubing. We also advise getting professional installation due to the danger of refrigerant spills.
