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 describe each of the common AC units.
- 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 various rooms in your home.
- Ductless mini-split: Ductless mini-split air conditioner systems have an exterior unit and multiple interior units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
- Portable air conditioners: As the name suggests, 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 preferred for condos, apartments, or individual rooms.
- Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They provide peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- Window ACs: Window air conditioners are a popular choice for Cupertino 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-mounted AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
How to Choose Your Cupertino AC Repair Service
With the sweltering Cupertino heat, AC issues are top priority 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 verify a company has sufficient liability insurance 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
Read 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 provider if most reviewers had subpar experiences.
Compare Estimates
Obtain at least three detailed, written estimates from different companies for the best price. 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.
