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.
