Common Types of Air Conditioners

There are a few different kinds of air conditioner units on the Belleville market. While HVAC technicians can work with most types, knowing which one you have will streamline your company search.

  • Portable air conditioners: As the name suggests, portable air conditioner systems 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.
  • Split ACs: Split air conditioner units have two main elements: one inside and one outside. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • 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.
  • Ductless mini-split: Ductless mini-split AC systems 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 Belleville 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 AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Belleville AC Repair Service

While you might want to resolve your AC issue quickly, you should do your research before committing to a repair service. Take the following steps to ensure you find the best company for your home.

Confirm the Company Is Properly Licensed and Insured

There's no state HVAC license in the Land of Lincoln. Instead, cities and counties are free to set their own requirements and regulations. Check with your local building department for more information.

You should also verify a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if something gets damaged during work.

Read Customer Reviews

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

It's normal for even the best AC repair companies to have both positive and negative reviews. Read each one carefully, and avoid a company 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 list additional fees such as permitting costs. You should also ask about installer guarantees, manufacturer warranties, and the emergency repair process.

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

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

Does my air conditioner need routine maintenance? If so, how often?

Homeowners should have their AC systems serviced every 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.

How many years until I should replace my AC unit?

With proper maintenance, your air conditioner's lifespan could be 10-15 years. Remember that parts often become obsolete as time goes on. If your HVAC contractor can't find a critical replacement part, you might need to consider getting a new air conditioner.

What industry certifications should I look for when researching Belleville AC repair companies?

Private accreditations might not be required, but firms 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).
