Common Types of Air Conditioners

There are a few different kinds of air conditioner units on the Walnut Creek market. While HVAC technicians can work with most types, knowing which one you have will streamline your company search.

  • Portable air conditioners: As the name implies, portable air conditioner systems 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 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 individual room temperature control, flexible installation options, and higher energy efficiency.
  • Central AC: These are the most common residential AC systems, offering precise, consistent 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.
  • Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They offer quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Walnut Creek condos, townhomes, and apartments. 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 AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Walnut Creek AC Repair Service

With Walnut Creek's blazing heat, AC problems are urgent to fix for your safety and comfort. 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 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 contractors that resolve 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 list additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.
