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 systems.
- 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 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.
- Ductless mini-split: Ductless mini-splits have an exterior 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 ACs have two main elements: one inside and one outside. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- Window-mounted ACs: Window air conditioners are a popular choice for Northfield condos, townhomes, and apartments. These budget-friendly, convenient 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 AC 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 some essential research before signing a contract with a repair service. Take the following steps to ensure you find the most suitable 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.
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 recognizes businesses 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 provider 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 include additional fees such as permitting costs. You should also ask about manufacturer warranties, installer guarantees, and the emergency repair process.
