Knowledgeable, Reasonable and Very Competent - A True Pleasure to Work With
We needed a new gas furnace and air conditioner. We contacted 3 companies, including the one that we currently had a maintenance contract for. We chose Debbie and her team because they were extremely thorough while evaluating what our house needed, and answered all my questions. It was amazing to have the person who came out to do the estimate leading the team that did the installation. The crew did an excellent job, we are very satisfied and have been recommending them to all of our friends.

Reliable Experts
Debbie and the team at Maryland Heating \& Cooling have now solved mechanical issues for us 3 times at 2 different homes. Their dedication, knowledge, and reliability have kept us coming back to them when we have mechanical issues. We were able to have them out to look at our existing system and schedule the work to replace in such a short amount of time. We will continue to use them as our service provider for years to come.

Off the chart service!!! When my AC went up in the midst of a heat wave, Maryland Heating and Cooling team (Debbie and Ron) were out the next day to check out my system and give me their recommendation. I needed a new system. They took their time, measured, explained the problem(s), gave me options and an estimate came via email that afternoon. 7 days later they returned and installed my wonderful new system. Hard workers, careful, neat and fun to be around. Debbie then showed me everything, carefully explained the care that should be taken, the directions to follow and then reviewed how to program the thermostat. It was wonderful. I am so happy with the entire process and I highly recommend Maryland Heating and Cooling!
A++ on all three attributes

Give them a chance and you will find they are the best
Fast service. If they can't fix your issue immediately, they will troubleshoot and give you advice over the phone. They offered to bring space heaters to my home. Their HVAC replacement estimate was $1,900 less than one of their competitors. They enjoy what they do and care about their customers. It comes shining through in everything they do.

Highly recommend!
MD Heating \& Cooling are no\-nonsense, honest, and thorough. They arrived on time and did the complete install, also replacing the kill switch box and thermostat, within 5\-1/2 hrs. They cleaned up and hauled all the old junk away. Debbie gave me pointers for care of the inside unit and showed me how to program the thermostat. They are professional and they do it right! I have used them for repair (old unit), and will continue to use them for maintenance of the new unit.

Maryland Heating and Cooling are honest and do everything right.
I am an engineer and I know everything about air conditioning. I could do the installation myself, but I do not have a permit to work with some freons, so I had to call a HVAC company to replace an old 2.5 ton heat pump system (that used R\-22) with a new 2.5 ton heat pump system (that uses R\-410A). I contacted 13 companies that work in my area. 9 of them told me that they are very busy and do not take new orders. 4 companies sent an estimator and gave me their proposals. Three of the four proposals included items that were not necessary, which is what pushed the prices way up. When two people from Maryland Heating and Cooling (Debbie and Ron) showed up they started to discuss with each other (in my presence) which items I do not need to replace, which would save me money. In the end they decided that none of the existing duct work needs to be modified and that the old copper lines are in good shape and can be re\-used. In the end they came up with the lowest price, significantly lower than the three other offers. Furthermore, they were able to do the installation on the second day after I signed the contract and paid the deposit. I was watching them while they did the work, and I am confident that they did everything right, because I understand exactly what they were doing and why. In other words, they did not cut any corners. I can recommend this company.
