Common Types of Air Conditioners

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

  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name implies, 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 condos, apartments, or individual rooms.
  • 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 different rooms in your home.
  • Ductless mini-split: Ductless mini-splits 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.
  • Window ACs: Window air conditioners are a popular choice for Seattle 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 deploy their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Seattle AC Repair Service

While you might want to resolve your AC issue quickly, you should carefully investigate what's out there 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

The Washington State Department of Labor and Industries requires all HVAC company owners to hold a Construction Contractor license. To stay in good standing, they must have a tax ID number, hold a surety bond, and carry at least $250,000 in total liability coverage.

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 accredits contractors that respond to complaints professionally and honor their warranties.

It's common for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a provider if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Seattle

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

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$68–$181
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$90–$226
Refrigerant leak$400–$1500
Frozen condenser coils$1,354–$4,062
Fan or air blower issues$150–$200
Compressor replacement$600–$1,715

Does my air conditioner need routine maintenance? If so, how often?

Homeowners should have their AC systems serviced at least once a year to ensure optimal performance. This usually involves cleaning the outdoor unit of brush and debris. Regular servicing can help to maintain the system's efficiency and prolong its lifespan.

What month is best for getting an air conditioner replaced?

To discover the best time for your installation, consider both the local weather and company demand. Generally, contractors get busier as the climate gets warmer and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely position a window AC unit by yourself. However, installing other air conditioners should almost always be done by an HVAC contractor who knows the intricate wiring, piping and tubing. We also advise seeking professional installation due to the risk of refrigerant spills.

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

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