Common Types of Air Conditioners
By understanding which type of air conditionermodel you have, you'll feel more empowered in your contractor search. San Mateo HVAC professionals have experience with different AC makes and models, and they can customize their skills to your needs.
- Window-mounted ACs: Window air conditioners are a popular choice for San Mateo 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 air conditioner users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
- Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
- Split ACs: Split AC units have two main elements: one inside and one outside. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- Portable air conditioners: As the name hints, portable air conditioner 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.
- 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 various rooms in your home.
How to Choose Your San Mateo AC Repair Service
While you might want to resolve your AC issue quickly, you should carefully investigate what's out there before hiring a repair service. Take the following steps to ensure you find the top-rated company for your home.
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 accidents happen during work.
Read Customer Reviews
Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits businesses that respond to 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 business if most reviewers had subpar experiences.
Compare Estimates
We advise getting three or more estimates to find the best cost and services. Get a written copy of each quote, and learn more about permitting fees, emergency repair availability, manufacturer warranties and installer guarantees.
