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

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

Frequently Asked Questions About AC Repair in Wentzville

How much can I expect to pay for AC repair in Wentzville?

Your air conditioner 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 switching 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
Thermostat$81–$204
Refrigerant leak$400–$1500
Frozen condenser coils$1,221–$3,664
Fan or air blower issues$150–$200
Compressor replacement$600–$1,547

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 Wentzville's weather patterns, this is usually between late September and the middle of November or early March to mid-May.

Is hiring an HVAC company better than doing the repair on my own?

Yes, it's better to get a new air conditioner professionally installed. Most units have intricate piping and wiring that can confuse even a seasoned do-it-yourselfer. They also use chemical refrigerants that could pose serious safety risks if they spill or leak. With their training and equipment, the right technician will set you up for success.

How many years until I should replace my AC unit?

You won’t need to change 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.

My HVAC problem is urgent. How quickly could a company respond?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. A number of companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the provider directly is best so you can get the most accurate information.
