Common Types of Air Conditioners

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

  • Split ACs: Split AC units have two main elements: one indoors and one outdoors. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Ductless mini-split: Ductless mini-split air conditioner systems 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.
  • Window-mounted ACs: Window air conditioners are a popular choice for Chesterfield 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 air conditioner users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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.
  • Portable air conditioners: As the name suggests, portable air conditioner units 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 popular for apartments, condos, or individual rooms.

How to Choose Your Chesterfield AC Repair Service

With the intense Chesterfield heat, AC issues are top priority to fix. However, to get the best possible outcome, it's critical to investigate different HVAC companies first. We recommend adhering to these steps as you prepare.

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.

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 businesses that respond to complaints professionally 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 business 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 factor in 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 Chesterfield

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

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 switching out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$65–$174
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$87–$217
Refrigerant leak$400–$1500
Frozen condenser coils$1,304–$3,912
Fan or air blower issues$150–$200
Compressor replacement$600–$1,652

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

Homeowners should have their AC systems serviced a minimum of 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 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 clog might be all that's necessary to get your AC cooling again.

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.

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

Private accreditations might not be required, but contractors 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).
