Common Types of Air Conditioners

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

  • Window ACs: Window air conditioners are a popular choice for Fullerton apartments, townhomes, and condos. 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split AC systems have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Split ACs: Split air conditioner systems have two main elements: one inside and one outside. They provide peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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 various rooms in your home.
  • Portable air conditioners: As the name suggests, portable air conditioner 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 preferred for apartments, condos, or individual rooms.

How to Choose Your Fullerton AC Repair Service

With Fullerton's blazing heat, AC problems are critical to fix for your comfort and safety. 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.

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 recognizes contractors that handle 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 business if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Fullerton

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

Your AC system 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 exchanging the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$67–$178
Electrical circuits$200–$250
Drainage problems$100–$150

Compressor replacement$600–$1,692

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.

How often should Fullerton homeowners have their AC systems serviced?

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

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.

Should my HVAC company have a private accreditation?

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).
