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 explain each of the common AC systems.

  • Portable air conditioners: As the name implies, 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 popular for apartments, condos, or individual rooms.
  • Split ACs: Split air conditioner units have two main elements: one indoors and one outdoors. They provide quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Boulder townhomes, condos, 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 install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
  • 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 Boulder AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before signing a contract with a repair service. Take the following steps to ensure you find the best company for your home.

Confirm the Company Is Properly Licensed and Insured

Colorado licenses plumbers and electricians at the state level, but not HVAC contractors. Counties and cities are free to issue their own licenses, and we encourage you to contact your local government for more information.

You should also confirm a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

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 companies to have both positive and negative reviews. Read each one carefully, and avoid a business 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 include additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.

Frequently Asked Questions About AC Repair in Boulder

How much can I expect to pay for AC repair in Boulder?

See the average costs for common AC repairs below.

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

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

What do I do if my AC is running but not cooling?

If your AC is running but not cooling, a clogged condenser coil could be the culprit. Normally, the AC’s condenser fan pulls air into the outdoor unit through the condenser coil to extract heat energy from your home. A technician can help by clearing the clog or replacing a faulty coil.

How long is my air conditioner's lifespan? When should I consider a replacement?

You won’t need to change air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become hard to find. You'll probably need to consider new AC installation if your company can't replace a broken part.

Should my HVAC company have a private accreditation?

Private accreditations aren't always necessary, but firms 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).
