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.

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

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.
