"We were having issues with our fireplace. The tech came to our house and was very professional, and quick to find out what the issue was. The price was fair, and we are really happy with the service. Would definitely hire them again for any service related to our AC or our fireplace, highly recommended!"

"They installed a new boiler and central air conditioning in my DC rowhome and did a fantastic job. Joe answered all of my questions and they stayed on schedule with the project which was great because it was a larger project. I would highly recommend their services for the quality of workmanship and their prices were very reasonable as well. I will contact them again for future HVAC work in the DC area."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"Overall McCrea did a good job with my Sept 23, 2019, HVAC installation. The POSITIVES significantly outweigh the negatives: · They had the best price out of 6 proposals. · They agreed to add an additional HVAC return to the basement free of charge ($250). · They leveled my second old existing heat pump without asking...free of charge…I really liked that. · They told me that Fairfax county does a free inspection upon request. I’ve never had an installer tell me this…it is not in their interest to do so. The county inspection was primarily electrical but it was good to have even that independently reviewed. · They responded within 2 hours after I called about an installation problem. It turned out a condensate PVC pipe was installed wrong and tripped a cutoff switch. Everyone makes mistakes. I give them credit on this one because they responded quickly and repaired it quickly. · I requested a Trane and NATE certified installer and McCrea sent out Greg Dworchak who, along with 2 others did an excellent job. They were competent and friendly and answered all my questions very well. One NEGATIVE: · I liked the first sales person (Kris Kimmmel) who gave the initial proposal...very professional and friendly. My only concern was that he went on vacation and the follow up was slow. He did tell me he would be on vacation with limited email access. I emailed my intention to move forward on the proposal by the required date but the response was too late to get the significant Trane rebate. Weeks later I received a call from another representative (Chris Aiani) and he provided an acceptable proposal although it was a lower SEER unit (XR14) instead of the XR16i I originally wanted. Chris apologized to me about this and said they were re-organizing to provide more sales support and that this should not happen again."

"Quickly diagnosed the central air conditioning system, and gave an estimate on the cost of recharging the refrigerant in the compressor. The system is a 14 year old Carrier unit. Albert also included some sealant that may plug up the slow leak of refrigerant that occurs every 2 years or so. Albert also, showed me how to adjust the damper to control the flow of air to the second and third floors of the house. The other company that arrived wanted to charge me $5,000 to repair the system or close to $7,000 to replace the AC system with new. I intend to call upon Magna Tech Temp Air, Inc when I'm ready to purchase a new HVAC system. Thanks again for taking the time to listen to my concerns. Well 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."

Air Conditioning questions, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.
