Common Types of Air Conditioners

There are a few different varieties of HVAC systems on the Northfield market. While HVAC professionals can work with most types, knowing which one you have will ease your company hunt.

  • Central AC: These are the most common home air conditioners, 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.
  • Portable air conditioners: As the name implies, portable AC 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 a common choice for apartments, condos, or individual rooms.
  • Ductless mini-split: Ductless mini-split air conditioner units have an exterior unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
  • Split ACs: Split air conditioners have two main elements: one indoors and one outdoors. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window-mounted ACs: Window air conditioners are a popular choice for Northfield townhomes, apartments, and condos. 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.

How to Choose Your Northfield 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 right 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 confirm a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that handle 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 company if most reviewers had subpar experiences.

Compare Estimates

Obtain at least three detailed, written estimates from different companies for the best value. A good estimate should consider additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.

Frequently Asked Questions About AC Repair in Northfield

What's the cost of an AC repair job in Northfield?

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 replacing the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$65–$173
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$86–$216
Refrigerant leak$400–$1500
Frozen condenser coils$1,295–$3,886
Fan or air blower issues$150–$200
Compressor replacement$600–$1,641

Why is my AC running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan draws air into the outdoor unit through the condenser coil to remove heat energy from your home. A technician can help by clearing the clog or replacing a faulty coil.

Why should I hire an HVAC professional? Couldn't I repair my air conditioner myself?

You can most likely set up a window AC unit by yourself. However, installing other AC units should almost always be done by an HVAC contractor who knows the complicated piping, tubing and wiring. We also advise opting for professional installation due to the danger of refrigerant spills.

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 ages, its mechanical parts might become obsolete. You'll probably need to consider new AC installation if your company can't replace a broken part.

Should my HVAC company have a private accreditation?

Private accreditations aren't always necessary, 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).
