"I contacted Sean to repair my aging HVAC system. Although I have very little knowledge of HVAC, Sean was able to identify, explain, and plan the maintenance of my current system in language I understood and that seemed reasonable. Sean was very responsive via text during our scheduling and I'm happy with the expert level of detail he showed during inspection. I would highly recommend working with him or his team. Update: Sean came back out to resolve my filtration issues and also fixed some other problems that he noticed in the process without increasing the negotiated price. Again, Iâ m extremely satisfied with the work heâ s done and would recommend him for your HVAC needs."

"I am SO pleased with this experience with GAC and highly recommend them! OUTSTANDING information and research on our behalf by Kelly for estimate options and finding the best unit and price for our needs. Chris was very impressive when he came to our home for preparation of the HVAC air handler/heat pump installment. Top notch work by John and the GAC crew on the actual work putting in my unit. They gave us the option and were qualified to run/install a new wire for our electric needs to have all energy savings of the equipment. Easy scheduling with Monica and follow-up too. ALL the GAC staff were happy to answer our various questions in full detail so we understood everything in this project and could make informed decisions. GAC found a high quality unit (Bryant) that suited our needs AND qualified for a PEPCO rebate, which they quickly filed on our behalf. We have been customers for years with GAC for maintenance and with this install, plan to be for years to come."

"Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected."

"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"I got four estimates before choosing Michael Bonsby. They were the only HVAC contractor to actually measure my house and recommended a system based on those measurements, which turned out to be a smaller and more affordable unit than my existing system. The other three just assumed the existing system was properly sized and proposed replacing it."

"Outstanding service and work. Very happy I chose them. I had an air handler/HVAC unit that was old and dirty. They came in, took it apart, cleaned/sprayed/lubricated the unit, put it back together, and it works so much better. Thank you!"

Heating and Air Conditioning questions, answered by experts

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
