Common Types of Air Conditioners

There are a few different kinds of air conditioners on the St. Joseph market. While HVAC professionals can work with most types, knowing which one you have will streamline your company research.

  • 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, individual room temperature control, and flexible installation options.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for St. Joseph condos, apartments, and townhomes. These compact, affordable 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.
  • 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 condos, apartments, or individual rooms.
  • Central AC: These are the most common residential AC systems, offering precise, consistent 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 St. Joseph AC Repair Service

While you might want to resolve your AC issue quickly, you should do your research before committing to a repair service. Take the following steps to ensure you find the most suitable company for your home.

Confirm the Company Is Properly Licensed and Insured

While Missouri licenses some contractors at the state level, it does not for HVAC companies. Local governments can set their own requirements, and we recommend contacting your town hall or county building department for more information.

You should also verify a company has sufficient liability 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

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 effectively and honor their warranties.

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

Compare Estimates

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

Frequently Asked Questions About AC Repair in St. Joseph

How much can I expect to pay for AC repair in St. Joseph?

Your AC repair costs will hinge on your system's make and model 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$61–$163
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,223–$3,670
Fan or air blower issues$150–$200
Compressor replacement$600–$1,550

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

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.

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 St. Joseph'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 AC is running but not cooling, a blocked 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.

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

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