"I had them replace my entire HVAC system (furnance + AC). They did a great job through the whole process. Out of four quotes I received, they were the only ones that took the time to do a full heating and cooling load calculation for my house when they came to do an estimate in addition to making detailed measurements of our utility room to make sure anything they installed would fit. They gave me three proposals ranging from low-end, mid-range, and high end options and explained the equipment in each of them in detail, including documenting all the model numbers, efficiency ratings, and specs. What they recommended matched up with my research I did prior to receiving estimates. They were very responsive, knowledgeable, and professional so I gave them the job. The crew arrived on time, worked hard the whole day, were respectful of my house, and did not require supervision (although, they told me I was more than welcome to ask questions and watch anything they were doing). They cleaned up, explained the warranty and rebate options with all the paperwork already filled out so that all I had to do was sign--they even mailed both the warranty and rebate off for me. The whole process went great. While their prices were fair they were not the cheapest, but I have no doubt they did a great job, didn't cut corners, and will stand by their work if I experience any problems. They are a reasonably sized HVAC business and not a one-man-band shop like many places in the area, so I know they will likely still be around through the life of the warranty and are well staffed to respond to emergencies, including a 24/7 emergency service number. Overall, we're very happy with the new system and it's a huge improvement over what it replaced--both the AC and furnace are much quieter than the old units, more energy efficient, and perform better. It's been a month since the install and everything has been working fine without problems."

"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."

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"On the hottest day of the year so far my A/C stopped working properly. I called No-Frost when they opened at 7am, Eileen called back within a few minutes, and a technician was at my door by 7:40. It was fixed and cooling the house within an hour. This is the company that installed my new HVAC system about 12 years ago, and they've been wonderful ever since. Eileen is great, and the technicians are polite and respectful, and keep you posted on what they are doing."

"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."

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

Heating and Air Conditioning questions, answered by experts

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Assessing location for airflow, convenience, and minimal noise impact.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

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.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
