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 explain each of the common AC systems.
- Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
- 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 condos, apartments, or individual rooms.
- Ductless mini-split: Ductless mini-splits have an outdoor unit and multiple interior units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
- Window ACs: Window air conditioners are a popular choice for Charleston apartments, condos, and townhomes. These budget-friendly, convenient 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.
- Central AC: These are the most common home air conditioners, 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.
How to Choose Your Charleston AC Repair Service
With Charleston's blazing 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.
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
Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that resolve 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, installer guarantees, and manufacturer warranties.
