Common Types of Air Conditioners

There are a few different kinds of air conditioners on the Bel Air South market. While HVAC contractors can work with most types, knowing which one you have will ease your company research.

  • Portable air conditioners: As the name suggests, 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 a common choice for condos, apartments, or individual rooms.
  • Ductless mini-split: Ductless mini-splits 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.
  • Window ACs: Window air conditioners are a popular choice for Bel Air South townhomes, apartments, and condos. These compact, affordable units are designed for cooling small spaces and single rooms, 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.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer peaceful operation, greater energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Central AC: These are the most common home air conditioners, offering consistent, precise 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 Bel Air South AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before recruiting a repair company, it's important to take the time to research if they're ideal for your dwelling. Here are a few essential steps to follow.

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 check a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if something gets damaged during work.

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 handle complaints professionally 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 company if most reviewers had subpar experiences.

Compare Estimates

We recommend getting at least three different estimates to find the best cost and services. Get a written copy of each quote, and learn more about emergency repair availability, manufacturer warranties, permitting fees and installer guarantees.

Frequently Asked Questions About AC Repair in Bel Air South

How much can I expect to pay for AC repair in Bel Air South?

Your AC repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$63–$167
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,251–$3,754
Fan or air blower issues$150–$200
Compressor replacement$600–$1,585

Does my air conditioner need routine maintenance? If so, how often?

Homeowners should have their AC systems serviced annually to ensure optimal performance. This usually involves cleaning the outdoor unit of brush and debris. Regular servicing can help to maintain the system's efficiency and prolong its lifespan.

When is the best time to replace an AC unit?

To discover the best time for your installation, consider both local weather patterns and company demand. Generally, contractors are more occupied as the climate warms up and less busy during the cooler months. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

Is hiring an HVAC company better than doing the repair on my own?

You can most likely position a window AC unit without professional help. However, installing other AC units should almost always be done by an HVAC contractor who knows the intricate wiring, piping and tubing. We also advise getting professional installation due to the danger of refrigerant spills.

What industry certifications should I look for when researching Bel Air South AC repair companies?

Private accreditations might not be required, but companies that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).
