Common Types of Air Conditioners

There are a few different varieties of HVAC models on the Wentzville market. While HVAC contractors can work with most types, knowing which one you have will streamline your company research.

  • Window ACs: Window air conditioners are a popular choice for Wentzville condos, townhomes, and apartments. 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 air conditioner users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split air conditioners have an outdoor unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • Split ACs: Split air conditioners have two main elements: one indoors and one outdoors. They provide silent operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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.
  • 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 Wentzville 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 carefully investigate how well it fits your home's needs. Here are a few essential steps to follow.

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

Find 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 normal for even the best AC repair providers 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 include additional fees such as permitting costs. You should also ask about manufacturer warranties, the emergency repair process, and installer guarantees.
