Common Types of Air Conditioners
HVAC technicians have the expertise to service most air conditioner models, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC units.
- Window ACs: Window air conditioners are a popular choice for Redwood City condos, apartments, and townhomes. These budget-friendly, convenient 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.
- 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 popular for condos, apartments, or individual rooms.
- Split ACs: Split ACs have two main elements: one inside and one outside. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- 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-splits have an outdoor unit and multiple interior units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
How to Choose Your Redwood City AC Repair Service
You likely want a swift resolution for your air conditioner's problem. However, before signing up with a repair company, it's important to carefully investigate how well it fits your home's needs. Here are a few essential steps to follow.
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 coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise 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 contractors that handle complaints professionally and honor their warranties.
It's normal for even the best AC repair companies 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 list additional fees such as permitting costs. You should also ask about the emergency repair process, installer guarantees, and manufacturer warranties.
