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.
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
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.
