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 describe each of the common AC units.
- 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.
- Window-mounted ACs: Window air conditioners are a popular choice for Rock Hill apartments, condos, and townhomes. 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Portable air conditioners: As the name hints, 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.
- Central AC: These are the most common residential AC systems, offering consistent, precise temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to different rooms in your home.
- Split ACs: Split ACs 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 Rock Hill AC Repair Service
With Rock Hill's sweltering heat, AC problems are critical to fix for your comfort and safety. However, don't rush to sign a contract until you're sure a company is the best fit for you. We recommend following these steps in your research.
Confirm the Company Is Properly Licensed and Insured
To work in the Palmetto State, HVAC companies must earn a Mechanical Contractor license from the Department of Labor, Licensing, and Regulation. New applicants must pass a comprehensive trade exam and present their business registration certificate. Companies from Texas, Louisiana, North Carolina, Ohio, Georgia, and Utah can apply for a license by reciprocity.
You should also confirm 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 accredits contractors that resolve complaints professionally and honor their warranties.
It's normal for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a business 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 installer guarantees, the emergency repair process, and manufacturer warranties.
