This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Types of Air Conditioners

By knowing which type of air conditioner you have, you'll feel more empowered in your provider search. La Mesa HVAC technicians have experience with different AC makes and models, and they can customize their skills to your needs.

  • Ductless mini-split: Ductless mini-splits 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 La Mesa condos, townhomes, and apartments. These compact, affordable 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.
  • Portable air conditioners: As the name implies, 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 preferred for condos, apartments, or individual rooms.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Central AC: These are the most common home air conditioners, 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.

How to Choose Your La Mesa AC Repair Service

With the sweltering La Mesa heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to thoroughly research different HVAC companies first. We recommend adhering to these steps as you prepare.

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 coverage, even if your state doesn't require it. Choosing an insured company will protect you if accidents happen during work.

Read Customer Reviews

Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that resolve 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 business if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in La Mesa

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

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
Refrigerant leak$400–$1500
Frozen condenser coils$1,285–$3,855
Fan or air blower issues$150–$200
Compressor replacement$600–$1,628

How often should La Mesa 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 month is best for getting an air conditioner replaced?

The best time to replace HVAC systems is during the off-season, when there's less demand for HVAC technicians and costs are cheaper. With La Mesa's hot average highs, the off season will usually be in the winter months when temperatures start to drop.

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 clog might be all that's necessary to get your AC back on track.

My HVAC problem is urgent. How quickly could a company respond?

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