5 Best AC Repair Services in Chillum, MD

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.

• Split ACs: Split air conditioner 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.
• Ductless mini-split: Ductless mini-split air conditioner units have an outdoor unit and one or more indoor units, with no ductwork required. They offer flexible installation options, individual room temperature control, and higher energy efficiency.
• Portable air conditioners: As the name implies, portable AC 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 apartments, condos, or individual rooms.
• Window ACs: Window air conditioners are a popular choice for Chillum townhomes, condos, and apartments. 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.
• 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.

How to Choose Your Chillum AC Repair Service

With Chillum's extreme heat, AC problems are critical to fix for your safety and comfort. However, don't race 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

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 verify a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.

Read Customer Reviews

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that handle complaints professionally and honor their warranties.

It's normal for even the best AC repair providers 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 providers for the best deal. A good estimate should consider additional fees such as permitting costs. You should also ask about installer guarantees, manufacturer warranties, and the emergency repair process.
