Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner models, but knowing more about what you have can be beneficial. Below, we'll outline each of the common AC models.

  • Window ACs: Window air conditioners are a popular choice for Jefferson City apartments, townhomes, and condos. 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 AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split AC units have an outdoor unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Portable air conditioners: As the name implies, portable ACs 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 preferred for apartments, condos, or individual rooms.
  • 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 various rooms in your home.
  • Split ACs: Split AC systems have two main elements: one indoors and one outdoors. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Jefferson City AC Repair Service

With the sweltering Jefferson City heat, AC issues are urgent to fix. However, to get the best possible outcome, it's critical to thoroughly research 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

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that respond to complaints professionally and honor their warranties.

It's common for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a provider if most reviewers had subpar experiences.

Compare Estimates

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

What are some signs that I should call an HVAC repair company?

Here are some of the most frequent AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

How often should Jefferson City homeowners have their AC systems serviced?

It's a good idea to service your AC at least annually. You can further maximize its efficiency and lifespan by keeping the outdoor unit clear of brush and debris.

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 ages, its mechanical parts might become hard to find. 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. Many companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the company directly is best so you can get the most accurate information.
