Common Types of Air Conditioners

By understanding which type of air conditionersystem you have, you'll feel more confident in your provider search. Gaithersburg HVAC technicians have experience with different AC makes and models, and they can tailor their skills to your needs.

  • Window ACs: Window air conditioners are a popular choice for Gaithersburg 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-split AC units have an outdoor unit and one or more indoor units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
  • 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.
  • Split ACs: Split AC systems have two main elements: one indoors and one outdoors. They provide peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name suggests, portable air conditioner units 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.

How to Choose Your Gaithersburg AC Repair Service

While you might want to resolve your AC issue quickly, you should carefully investigate what's out there 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

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

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 companies to have both positive and negative reviews. Read each one carefully, and avoid a provider if most reviewers had subpar experiences.

Compare Estimates

We advise getting three or more estimates to find the best value. Get a written copy of each quote, and learn more about installer guarantees, permitting fees, emergency repair availability and manufacturer warranties.
