"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."

"I purchased the Angie's List deal for having our whole house air ducts cleaned and sanitized for $199. Our vents were very dirty having undergone two major house renovations. Because of how our vents are set up, our technician Val told us that they would be very hard to clean (we living in a 1959 rambler) and we might require multiple cleanings. As they were working, the weren't aware of the amount of dust that was being scattered throughout the house, again, due to the setup of our venting system. After he left, I needed to go throughout the house and clean the thing layer of dust that had settled on all surfaces. Val felt awful and apologized multiple times and you could tell that he was being sincere. He did recommend that we use an anti-bacteria and fumigation treatment because of mold he found in the vents (which he showed us pictures of) and had recommended purchasing a UV lamp to stop the growth of mold in the future. We opted to forgo the UV lamp, but purchase the additional cleaning options, which should have cost $275. It was clear that Val felt bad about the dust in the house because after we agreed to the additional cleaning, he dropped the price to $175 and also cleaned our dryer vent for free."

"We had our vents cleaned by Hydro Clean and it was a great experience.  The workers were very friendly and knowledgeable.  We live in a small rowhome with very narrow staircases.  Due to this issue they could not get their machine into our basement.  At first the workers left and gave us a recommendation for other options.  Not long after they left the manager called and said they were on their way back and there was something else they could do after all.  He was very  nice and so were the workers who had to come back.  I really appreciated him going the extra mile instead of just letting it be someone else's problem.

"Randy Stevens of BlueDot in Maryland was an absolute professional. Exceptionally experienced, very thorough in his craft, and otherwise a wonderfully pleasant technician to work with. I had BlueDot completely redo my entire AC system last year, and BlueDot continues to provide to me support and assistance when things come up. In this case I had a plumbing issue that was tangentially related to HVAC drain line, and Randy diligently ruled out the HVAC as the source of the problem and helped me locate the exact location where the issue was coming from. Today that issue is fully resolved. Thank you!"

Air Conditioning questions, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
