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 describe each of the common AC systems.
- Window-mounted ACs: Window air conditioners are a popular choice for Palo Alto condos, townhomes, and apartments. 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Split ACs: Split air conditioner systems have two main elements: one indoors and one outdoors. They provide peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- 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.
- Portable air conditioners: As the name suggests, portable AC units 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 apartments, condos, or individual rooms.
- Ductless mini-split: Ductless mini-split ACs have an exterior unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
How to Choose Your Palo Alto AC Repair Service
With Palo Alto's intense heat, AC problems are critical to fix for your comfort and safety. However, don't race to sign a contract until you're sure 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 accredits businesses that respond to complaints effectively and honor their warranties.
It's common 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 companies for the best value. A good estimate should include additional fees such as permitting costs. You should also ask about manufacturer warranties, installer guarantees, and the emergency repair process.
