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 systems.

  • Portable air conditioners: As the name hints, portable air conditioner 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 condos, apartments, or individual rooms.
  • Split ACs: Split AC units have two main elements: one indoors and one outdoors. They offer silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Window ACs: Window air conditioners are a popular choice for Potomac 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 install 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 different rooms in your home.
  • Ductless mini-split: Ductless mini-split ACs have an outdoor unit and multiple interior units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.

How to Choose Your Potomac 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 most reliable company for your home.

Confirm the Company Is Properly Licensed and Insured

Maryland HVAC contractors need licensure from the Board of Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) Contractors. A master license requires three years of journeyman experience, 1,875 hours of HVAC work performed in the last year, and a comprehensive trade exam.

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 businesses that respond to complaints professionally and honor their warranties.

It's common 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 price. 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.
