Common Types of Air Conditioners

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

  • Ductless mini-split: Ductless mini-splits 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.
  • Window-mounted ACs: Window air conditioners are a popular choice for Waldorf 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Portable air conditioners: As the name implies, 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 popular for apartments, condos, or individual rooms.
  • Central AC: These are the most common home air conditioners, 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.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They provide silent operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.

How to Choose Your Waldorf AC Repair Service

You likely want a quick solution for your air conditioner's problem. However, before signing up with a repair company, it's important to do careful research to ensure it's the best for your home. 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.

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

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that handle complaints effectively 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 provider if most reviewers had subpar experiences.

Compare Estimates

We suggest 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, installer guarantees, permitting fees and manufacturer warranties.

Frequently Asked Questions About AC Repair in Waldorf

What's the cost of an AC repair job in Waldorf?

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

Compressor replacement$600–$1,661

What are some signs that I should call an HVAC repair company?

Here are several of the most frequent AC issues you might face: It's best to contact a professional HVAC technician if you encounter any of these problems.

Why is my AC running but not cooling?

If your air conditioner is running but not cooling, a technician will usually check the condenser coil first. Normally, the outdoor unit fans draw air into the coil so the system can extract heat energy from your home. Clearing the obstruction might be all that's necessary to get your AC working again.

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

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

What industry certifications should I look for when researching Waldorf AC repair companies?

Private accreditations might not be required, but contractors 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).
