Common Types of Air Conditioners

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

  • 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 apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-splits have an outdoor unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • Central AC: These are the most common residential AC systems, offering precise, consistent temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to various rooms in your home.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer silent operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Madison apartments, condos, and townhomes. These budget-friendly, convenient units are designed for cooling small spaces and single rooms, 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 Madison AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before signing up with a repair company, it's important to do careful research to ensure it's the best for your home. Here are a few essential steps to follow.

Confirm the Company Is Properly Licensed and Insured

Wisconsin HVAC contractors are licensed through the Department of Safety and Professional Services. Even with this license, an HVAC company must still subcontract electrical and plumbing work.

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

Read Customer Reviews

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that handle complaints effectively 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

Obtain at least three detailed, written estimates from different providers for the best value. 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 Madison

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

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$65–$173

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

Here are several 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.

How often should Madison homeowners have their AC systems serviced?

Homeowners should have their AC systems serviced 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.

Is hiring an HVAC company better than doing the repair on my own?

Yes, it's better to get a new air conditioner professionally installed. Most units use complex piping and wiring that could stump even a seasoned do-it-yourselfer. They also use chemical refrigerants that could pose dangers if they spill or leak. With their training and equipment, the right technician will set you up for success.

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 ages, its mechanical parts might become unavailable. You'll probably need to consider new AC installation if your company can't install a broken part.
