Common Types of Air Conditioners

There are a few different varieties of air conditioners on the Flagstaff market. While HVAC technicians can work with most types, knowing which one you have will simplify your company search.

  • Window-mounted ACs: Window air conditioners are a popular choice for Flagstaff 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 deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer silent operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Ductless mini-split: Ductless mini-splits 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.
  • 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 preferred for apartments, condos, 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 and purifies outside air and sends it through ducts to different rooms in your home.

How to Choose Your Flagstaff AC Repair Service

With Flagstaff's sweltering heat, AC problems are urgent 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

The Arizona Registrar of Contractors has multiple different license classifications for HVAC contractors. For a C-39 (Air Conditioning and Refrigeration) classification, a contractor must have four years of experience and pass two exams. Contractors might also have a C-38 classification allowing them to work with heating, ductwork, and evaporative cooling systems.

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

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits businesses that handle complaints professionally 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 provider if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Flagstaff

What's the cost of an AC repair job in Flagstaff?

Your AC repair costs will hinge on the type of unit you have and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$59–$158
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,186–$3,557
Fan or air blower issues$150–$200
Compressor replacement$600–$1,502

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

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

What month is best for getting an air conditioner replaced?

The best time to replace HVAC systems is during the off-season, when there's less demand for HVAC technicians and costs are cheaper. With Flagstaff's weather patterns, this is usually between late September and the middle of November or early March to mid-May.

Why is my AC 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 remove heat energy from your home. A technician can help by clearing the clog or replacing a damaged coil.

What industry certifications should I look for when researching Flagstaff AC repair companies?

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