This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Types of Air Conditioners

By understanding which type of air conditioner you have, you'll feel more empowered in your contractor search. Corona HVAC professionals have experience with different AC makes and models, and they can adapt their skills to your needs.

  • Portable air conditioners: As the name hints, 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 a common choice 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 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 Corona apartments, townhomes, 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.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Corona AC Repair Service

With Corona's 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

Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that resolve complaints professionally 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 business if most reviewers had subpar experiences.

Compare Estimates

We advise getting contacting at least three different companies to find the best pricing and offerings. Get a written copy of each quote, and learn more about emergency repair availability, manufacturer warranties, installer guarantees and permitting fees.

What are some signs that I should call an HVAC repair company?

Here are some of the most frequent AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

How often should Corona homeowners have their AC systems serviced?

It's a good idea to service your air conditioner at least once a year. You can further maximize its lifespan and efficiency by keeping the outdoor unit clear of brush and debris.

How many years until I should replace my AC unit?

With regular care, your air conditioner's lifespan could be 10-15 years. Remember that parts frequently become obsolete as time goes on. If your installer can't find a critical replacement part, you might need to consider installing a new AC.

Should my HVAC company have a private accreditation?

Private accreditations aren't always necessary, but contractors that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).
