Common Types of Air Conditioners

By understanding which type of air conditioner you have, you'll feel more empowered in your provider search. Altadena HVAC contractors have experience with different AC makes and models, and they can tailor their skills to your needs.

  • Split ACs: Split AC units have two main elements: one indoors and one outdoors. They offer quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name hints, portable air conditioners 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 popular for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Central AC: These are the most common residential AC systems, offering consistent, precise 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.
  • Window ACs: Window air conditioners are a popular choice for Altadena townhomes, condos, 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 AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Altadena AC Repair Service

With Altadena's scorching heat, AC problems are critical to fix for your comfort and safety. However, don't rush to sign a contract until you know 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 check a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise 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 contractors that respond to complaints effectively 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 company 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 consider additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.

Frequently Asked Questions About AC Repair in Altadena

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

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$63–$168
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$84–$210
Refrigerant leak$400–$1500
Frozen condenser coils$1,259–$3,777
Fan or air blower issues$150–$200
Compressor replacement$600–$1,595

When is the best time to replace an AC unit?

To find the best time for your installation, consider both the local weather and company demand. Generally, contractors are more occupied as the climate gets warmer and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

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 draws 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.

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 installer can't find a critical replacement part, you might need to consider installing a new AC.

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

Some repair companies offer same-day or next-day service for emergency air conditioner breakdowns. However, the specific timeframe will vary depending on the team's schedule, the terms in your contract, and the severity of the issue. For the most accurate info, we recommend contacting the provider directly and explaining the situation.
