Common Types of Air Conditioners
By understanding which type of air conditioner you have, you'll feel more empowered in your provider search. Altadena HVAC contractors have experience with different AC makes and models, and they can tailor their skills to your needs.
- Split ACs: Split AC units have two main elements: one indoors and one outdoors. They offer quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- 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 apartments, condos, or individual rooms.
- Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
- Central AC: These are the most common residential AC systems, 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.
- Window ACs: Window air conditioners are a popular choice for Altadena townhomes, condos, and apartments. 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 AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
How to Choose Your Altadena AC Repair Service
With Altadena's scorching heat, AC problems are critical to fix for your comfort and safety. However, don't rush to sign a contract until you know 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
Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that handle complaints professionally and honor their warranties.
It's normal 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 providers for the best deal. A good estimate should consider additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.
