"I have nothing but kind words and gratefulness for this company. I am a senior citizen who lives alone. On 21 Jan (the day before) the snow storm, I awoke to no heat in the house (which is an old house). Got on Home Advisor hoping I could get immediate relief but realistically knowing what the odds were. I quickly received phone from John and told him my misfortune and he came right over to take a look. Bottom line, he and his crew of guy removed and installed a new HVAC (which I knew was coming) for what I considered a reasonable prices. Those guys literally saved my life. I would high recommend them to everyone. They are highly professional and get the job done!"

"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."

"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"

"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

Heating and Air Conditioning questions, answered by experts

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.
