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 types.

  • Split ACs: Split air conditioners have two main elements: one indoors and one outdoors. They offer peaceful 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 and purifies outside air and sends it through ducts to various rooms in your home.
  • Window-mounted ACs: Window air conditioners are a popular choice for Brentwood apartments, townhomes, and condos. 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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 flexible installation options, individual room temperature control, and higher energy efficiency.

How to Choose Your Brentwood AC Repair Service

With Brentwood's intense 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

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

Compare Estimates

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

Frequently Asked Questions About AC Repair in Brentwood

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

Your AC 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 switching 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

How often should Brentwood 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.

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

Yes, it's better to get a new air conditioner professionally installed. Most units have complex wiring and piping that could stump even a seasoned do-it-yourselfer. They also use refrigerants that could pose dangers if they spill or leak. With their training and equipment, the right technician will set you up for success.

How long is my air conditioner's lifespan? When should I consider a replacement?

You won’t need to change air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become hard to find. You'll probably need to consider new AC installation if your company can't replace a broken part.

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

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 contractor directly and explaining the situation.
