Common Types of Air Conditioners
HVAC technicians have the expertise to service most air conditioner types, but knowing more about what you have can be beneficial. Below, we'll outline each of the common AC models.
- 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.
- Window ACs: Window air conditioners are a popular choice for Durham apartments, condos, and townhomes. 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-mounted AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
- Portable air conditioners: As the name suggests, 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 popular for condos, apartments, or individual rooms.
- Ductless mini-split: Ductless mini-split air conditioner systems have an exterior unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
- Split ACs: Split AC systems have two main elements: one indoors and one outdoors. They provide quiet operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
How to Choose Your Durham AC Repair Service
While you might want to resolve your AC issue quickly, you should do your research before hiring a repair service. Take the following steps to ensure you find the top-rated company for your home.
Confirm the Company Is Properly Licensed and Insured
The North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses, regulates, and hears complaints about AC repair companies. To apply, business owners must pass a comprehensive exam, financial audit, and background check. Crew members under the owner don't need a license.
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 accidents happen during work.
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 effectively and honor their warranties.
It's normal 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 providers for the best price. A good estimate should consider additional fees such as permitting costs. You should also ask about installer guarantees, manufacturer warranties, and the emergency repair process.
