"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."

"Moises came out the same day that I requested an estimate for the installation of a UV light whole house air purification system, and to chemically clean my AC coil. I had another estimate but Moises gave me a better deal. He also recommended getting a cover for my AC unit for the winter, when he opened it up it was full of leaves and debris. I am very satisfied with the work that was done and would highly recommend MSR."

"It started off with requesting a quote through Best Air Quality and Restoration. The response time was great. The technician who showed up informed us in advance of his arrival, was very polite, followed Covid-19 safety protocols, was very thorough and did a great job. I also got the dryer vent cleaning which was the complete deal (going to the attic, removing the vent pipe and cleaning the debris). Some other companies claim they do dryer vent cleaning but only vacuum the dryer duct and do not perform the complete dryer vent cleaning which is more involved. I'm very happy with the service and this company and have already recommended them too many of my friends. Keep up the great service Best Air Quality and Restoration!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"The technician that cleaned my ductwork had a lot of work to do. Milan had asked me as he was leaving how long had it been since I had the ducts cleaned. I couldn’t recall, then realized it was a long time ago. 30 years! As a new homeowner I had zero experience so I was relying on my husband. He died 5 years after we bought this house and being clueless about the care & upkeep on it. I neglected pretty much everything. Lowes the Company offered the same exact cleaning as 2 other companies that gave me estimates over $1,000. Lowes has 3 flat rates to choose from, I chose the $398 special and that’s exactly what I paid. Great Company with Great prices!"

Air Conditioning questions, answered by experts

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.
