Common Types of Air Conditioners
HVAC technicians have the expertise to service most air conditioner varieties, but knowing more about what you have can be beneficial. Below, we'll outline each of the common AC models.
- Split ACs: Split air conditioner 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.
- Ductless mini-split: Ductless mini-split air conditioner systems have an outdoor unit and multiple interior units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.
- Window-mounted ACs: Window air conditioners are a popular choice for Los Angeles townhomes, apartments, and condos. These compact, affordable 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 deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
- Portable air conditioners: As the name hints, portable air conditioners 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.
- Central AC: These are the most common residential AC systems, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to different rooms in your home.
How to Choose Your Los Angeles AC Repair Service
With Los Angeles' extreme heat, AC problems are critical to fix for your safety and comfort. However, don't rush to sign a contract until you're convinced a company is the best fit for you. We recommend following these steps in your research.
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.
Many states and cities also require companies to carry liability insurance. Even if your community doesn't require it, we still recommend choosing an insured company. This will protect you if an accident happens or something gets damaged.
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 company if most reviewers had subpar experiences.
Compare Estimates
Obtain at least three detailed, written estimates from different companies for the best deal. A good estimate should include additional fees such as permitting costs. You should also ask about installer guarantees, the emergency repair process, and manufacturer warranties.
