5 Best AC Repair Services in Rockville, MD

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 describe each of the common AC units.

• Split ACs: Split air conditioner units have two main elements: one inside and one outside. They offer peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
• Ductless mini-split: Ductless mini-split AC systems have an exterior unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, individual room temperature control, and flexible installation options.
• 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 preferred for condos, apartments, or individual rooms.
• Central AC: These are the most common residential AC systems, offering precise, consistent 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.
• Window-mounted ACs: Window air conditioners are a popular choice for Rockville condos, townhomes, and apartments. These budget-friendly, convenient units are designed for cooling small spaces and single rooms, and they fit snugly in a window frame or dedicated wall slot. Many window AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.

How to Choose Your Rockville AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before committing to 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

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.

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 mishaps arise during work.

Read Customer Reviews

Read customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that handle complaints effectively 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 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 include additional fees such as permitting costs. You should also ask about installer guarantees, the emergency repair process, and manufacturer warranties.
