Common Types of Air Conditioners

There are a few different types of air conditioner units on the Beloit market. While HVAC professionals can work with most types, knowing which one you have will simplify your company research.

  • Window ACs: Window air conditioners are a popular choice for Beloit townhomes, condos, and apartments. These compact, affordable 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.
  • Portable air conditioners: As the name implies, portable air conditioners 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-split air conditioner units have an outdoor unit and one or more indoor 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 precise, consistent temperature control. They feature a central unit that cools and purifies outside air 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 provide quiet operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Beloit AC Repair Service

You likely want a swift resolution 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.

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

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

Compare Estimates

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

Frequently Asked Questions About AC Repair in Beloit

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

Your air conditioner 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 exchanging the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$61–$163
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,221–$3,664
Fan or air blower issues$150–$200
Compressor replacement$600–$1,547

When is the best time to replace an AC unit?

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 Beloit's weather patterns, this is usually between late September and the middle of November or early March to mid-May.

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

If your air conditioner is running but not cooling, a contractor will usually check the condenser coil first. Normally, the outdoor unit fans draw air into the coil so the system can extract heat energy from your home. Removing the blockage might be all that's necessary to get your AC cooling again.

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

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

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

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