Common Types of Air Conditioners
By understanding which type of air conditioner you have, you'll feel more empowered in your company search. San Bruno HVAC technicians have experience with different AC makes and models, and they can adapt their skills to your needs.
- Central AC: These are the most common home air conditioners, 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 AC systems have two main elements: one inside and one outside. They offer peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- Window ACs: Window air conditioners are a popular choice for San Bruno condos, townhomes, and apartments. 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Portable air conditioners: As the name suggests, 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.
- Ductless mini-split: Ductless mini-split AC systems have an outdoor unit and one or more indoor units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.
How to Choose Your San Bruno AC Repair Service
With San Bruno's intense heat, AC problems are urgent to fix for your comfort and safety. However, don't race 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 confirm a company has sufficient liability 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
Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that respond to complaints effectively and honor their warranties.
It's normal 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 providers for the best value. 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.
