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 units.

  • Central AC: These are the most common home air conditioners, offering consistent, precise 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.
  • Ductless mini-split: Ductless mini-split air conditioner systems have an exterior unit and multiple interior units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
  • Portable air conditioners: As the name suggests, 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 air conditioner units have two main elements: one indoors and one outdoors. They provide peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Cupertino apartments, condos, and townhomes. These compact, affordable 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.

How to Choose Your Cupertino AC Repair Service

With the sweltering Cupertino heat, AC issues are top priority to fix. However, to get the best possible outcome, it's critical to investigate 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 verify a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if something gets damaged during work.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that respond to complaints effectively and honor their warranties.

It's common for even the best AC repair providers to have both positive and negative reviews. Read each one carefully, and avoid a provider 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 factor in 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 Cupertino

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

Your AC unit 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 changing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$67–$179
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$90–$224
Refrigerant leak$400–$1500
Frozen condenser coils$1,345–$4,036
Fan or air blower issues$150–$200
Compressor replacement$600–$1,704

How often should Cupertino 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.

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

You can most likely set up a window AC unit by yourself. However, installing other air conditioners should almost always be done by an HVAC contractor who knows the intricate tubing, piping and wiring. We also advise seeking professional installation due to the risk of refrigerant spills.

Should my HVAC company have a private accreditation?

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).

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

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 company directly is best so you can get the most accurate information.
