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 outline each of the common AC units.

  • Ductless mini-split: Ductless mini-splits have an outdoor unit and multiple interior units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
  • 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 a common choice for apartments, condos, or individual rooms.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They provide peaceful 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, condos, and townhomes. 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 AC 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 top priority 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 confirm a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if accidents happen during work.

Read Customer Reviews

Find 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 business if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Sunnyvale

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

See the average costs for common AC repairs below.

Common RepairAverage Cost

Electrical circuits$200–$250

What are some signs that I should call an HVAC repair company?

Here are some of the most common AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

When is the best time to replace an AC unit?

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 AC is running but not cooling, a clogged 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 defective coil.

Should my HVAC company have a private accreditation?

Private accreditations might not be required, 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).
