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 systems.

  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for San Diego townhomes, apartments, 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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, higher energy efficiency, and individual room temperature control.
  • Portable air conditioners: As the name hints, 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 a common choice for apartments, condos, or individual rooms.
  • Central AC: These are the most common home air conditioners, offering precise, consistent temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to different rooms in your home.

How to Choose Your San Diego AC Repair Service

While you might want to resolve your AC issue quickly, you should carefully investigate what's out there before committing to a repair service. Take the following steps to ensure you find the top-rated company for your home.

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 check a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

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 professionally and honor their warranties.

It's common 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

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

Frequently Asked Questions About AC Repair in San Diego

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

Your AC 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$64–$171
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$86–$214
Refrigerant leak$400–$1500
Frozen condenser coils$1,285–$3,855
Fan or air blower issues$150–$200
Compressor replacement$600–$1,628

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

It's a good idea to service your air conditioner at least annually. 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 air conditioner is running but not cooling, a contractor 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 working again.

How many years until I should replace my AC unit?

With proper care, your air conditioner's lifespan could be 10-15 years. Remember that parts frequently become obsolete as time goes on. If your HVAC contractor can't find a critical replacement part, you might need to consider installing a new AC.

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

Private accreditations aren't always necessary, but companies 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).
