Common Types of Air Conditioners

There are a few different kinds of air conditioner systems on the Sunnyvale market. While HVAC contractors can work with most types, knowing which one you have will ease your company hunt.

  • Ductless mini-split: Ductless mini-split ACs have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Portable air conditioners: As the name implies, portable AC units 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.
  • Split ACs: Split air conditioners have two main elements: one inside and one outside. They provide quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Sunnyvale apartments, townhomes, and condos. These budget-friendly, convenient 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 air conditioner users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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 different rooms in your home.

How to Choose Your Sunnyvale AC Repair Service

With the intense Sunnyvale heat, AC issues are urgent 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.

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 recognizes businesses that handle 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 provider if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Sunnyvale

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

Your air conditioner 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 exchanging 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

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 Sunnyvale's hot average highs, the off season will usually be in the winter months when temperatures start to drop.

What do I do if my AC is 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 working again.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely position a window AC unit by yourself. However, installing other AC units should almost always be done by an HVAC contractor who knows the complicated tubing, piping and wiring. We also advise getting professional installation due to the danger of refrigerant spills.

Should my HVAC company have a private accreditation?

Private accreditations might not be required, but firms 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).
