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

HVAC technicians have the expertise to service most air conditioner types, but knowing more about what you have can be beneficial. Below, we'll outline each of the common AC units.

  • Split ACs: Split ACs have two main elements: one inside and one outside. They provide quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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 popular for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
  • Central AC: These are the most common home air conditioners, offering consistent, precise temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
  • Window ACs: Window air conditioners are a popular choice for Oceanside 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-mounted AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Oceanside AC Repair Service

With the intense Oceanside heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to thoroughly research different HVAC companies first. We recommend adhering to these steps as you prepare.

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 resolve 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 business if most reviewers had subpar experiences.

Compare Estimates

We advise getting three or more estimates to find the best cost and services. Get a written copy of each quote, and learn more about emergency repair availability, installer guarantees, manufacturer warranties and permitting fees.

How do I know if my air conditioning system needs repair?

Here are several 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 long is my air conditioner's lifespan? When should I consider a replacement?

With adequate maintenance, your air conditioner's lifespan could be 10-15 years. Remember that parts frequently become obsolete as time goes on. If your HVAC contractor can't find a critical replacement part, you might need to consider getting a new air conditioner.

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).

How quickly can an HVAC company in Oceanside respond to emergency repair requests?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. Some companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the provider directly is best so you can get the most accurate information.
