This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

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 explain each of the common AC units.

  • Split ACs: Split AC units have two main elements: one indoors and one outdoors. They offer silent operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Central AC: These are the most common residential AC systems, 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-split ACs have an exterior unit and one or more indoor units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
  • Window-mounted ACs: Window air conditioners are a popular choice for Florissant condos, townhomes, and apartments. 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 air conditioner users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Portable air conditioners: As the name hints, 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 popular for apartments, condos, or individual rooms.

How to Choose Your Florissant AC Repair Service

With Florissant's scorching heat, AC problems are critical to fix for your safety and comfort. However, don't race to sign a contract until you're convinced a company is the best fit for you. We recommend following these steps in your research.

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 check a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if accidents happen during work.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that respond to 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 business if most reviewers had subpar experiences.

Compare Estimates

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

Frequently Asked Questions About AC Repair in Florissant

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

Your AC unit 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 replacing 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 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.

When is the best time to replace an AC unit?

To discover the best time for your installation, consider both Florissant's temperatures and company demand. Generally, contractors are more in demand as the weather gets warmer and less busy during cool seasons. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

How many years until I should replace my AC unit?

You won’t need to buy a new air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become unavailable. You'll probably need to consider new AC installation if your company can't replace a broken part.

Should my HVAC company have a private accreditation?

Private accreditations aren't always necessary, 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).
