HVAC reviews in Baltimore, Maryland

Used them in the past. Prices are just not affordable for me, and even worse, the repair I had was misdiagnosed. Used another company who I have been very happy with.

Our A/C unit has been acting up the last month and John and Isaiah came analyzed the problems, and fixed them. Professional, friendly and took time to walk me through repairs made in detail. What more could I ask for?

For more than 12 years, we have utilized Millennium Heating and Cooling company. Excellent craftsmanship, and every technician we dealt with was really professional, kind, and knowledgeable. Highly recommended.

Dennis came and was friendly from the start. He gave us great, detailed information and even helped us get a maintenance schedule for our air conditioner and water heater. Highly encourage you to use this company.

Millennium Heating and Cooling lived up to their guaranteed troubleshooting deal and solved my furnace problems. Denis exemplified tenacity and a positive attitude while faced with extreme challenge. I'm happy with how he handled my furnace problem. I would recommend Him and Millennium Heating and Cooling to my family and friends.

Dennis was AMAZING. From the moment he walked in, he was personable, informative, and respectful. He also came highly recommended (we can see why). He broke everything down for my husband and I and gave us every option and made us feel like he wanted the best for us and our home (& we are not just a number or a name on a screen). You would be BLESSED to get Casey as your tech.

On Sunday, July 31st, I contact Millennium HVAC services to diagnosis aCentral AC system at a rental property that I own. My tenant complained that cool air was not coming from the vents. Upon calling on Sunday, Millennium scheduled a technician to come out on Monday, 8/1. The technician arrived and after investigating the system, he called me to inform me the system was in good shape, but it was low on refrigerant. At this time I said please proceed with adding refrigerant to the system. The technician stated he didn't have the type of refrigerant on hand and he would need to order it and it should take a few days. This was agreed on and I pre-paid$344.50(refrigerant) + 250.00(diagnostic fee) for the service. Five days past with no contact from the tech or company. I called on Friday, 8/5 to get a status and they said they would call me back(I never received a call). With a heat wave in MD, I had to contact another company to investigate the system since my tenant was without proper AC for 5 days. The 2nd company(Horizon HVAC Services), came out investigated the system, found the refrigerant levels were fine, but it was an electrical issue feeding the outside condenser. They fixed the issue and the system began working. On Monday, August 8th I called Millennium, explaining the mis-diagnosis by their tech, the lack of return calls, and I asked for the $344.50 back. They said someone would call me back after opening a billing department service ticket. I didn't receive a call back the entire day. I called back onAugust 9th, again no resolution, and no call back after asking to speak to someone directly in billing. I have used several HVAC companies over the years for my rental properties and this the worst customer service I have ever experienced. I had to submit a complain to the BBB of Maryland, because of lack of response from this company.

The technician was incredibly knowledgeable and super polite and professional. This was by far the best experience I have ever had with a heat/air service provider since owning my home for more than 20 years. I will recommend Millennium Heating and Cooling any chance I get and look forward to great service for years to come.
