"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"We were extremely happy with our entire experience. Grove responded quickly to our inquiry - provided a quote the next day and started the day after that. Our attic air handler was very difficult to access and Grove had a "can do" attitude about the entire installation. The price was comparable to other bids - but for a better system and with a much better explanation. They were on time, complete, and clean. We will absolutely use them again."

"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 replaced my furnace and AC unit, I bid the work and Beltway was far less than the other 4 companies that quoted us. Their work and professionalism was spectacular. I did all the leg work, this company was by far the best out there in my opinion. I couldn't be happier."

"I had a great experience with this HVAC company! They were professional, arrived on time, and quickly diagnosed the issue with my air conditioning unit. They explained the repair clearly, completed the work efficiently, and had my AC running perfectly again. The technician was courteous, knowledgeable, and took the time to answer all of my questions. I really appreciated the honest service and fair pricing. I highly recommend them to anyone looking for reliable HVAC service!"

"I hired Best Air Quality and Restoration to clean my dryer vent. I was very pleased with their level of professionalism. All my questions were answered without hesitation. The price was fair and affordable. Dennis, the technician notified me of his expected arrival time. He was very nice and pleasant. Dennis explained what the job entailed and completed the job within an hour. There was no excess lint or debris in my home to clean. I would recommend Best Air Quality and Restoration to others to experience for themselves. I intend to use other Best Air Quality and Restoration services again in the near future."

"Alan came on time and thoroughly evaluated my home's HVAC and duct system. He agreed that the duct work that I wanted done would likely solve the issue with my system and home. He was much more thorough that he could have been to satisfy my needs. I already had a quote for a much higher amount from Supreme Service Today who has been servicing my home for about three years. Suspecting that Supreme Service Today's quote was very high, I turned to Angi to get competitive bids. Since I had a bid at a much more reasonable price from Alan at One Hour Heating and Air, I contacted Supreme Service Today and asked for a price match. They were willing to match the much lower price from One Hour Heating and Air, so I gave the business to the HVAC contractor that I've been working with for a few years. Good deal! (: Soon I may break my ongoing contract with Supreme Service and come to One Hour Heating and Air !! :)"

"JDL price was very reasonable and they did a great job installing a mini split heat pump. The installation is clean and neat. The guys were very professional. Thanks Armando for leading the team during this installation. I should not forget the office staff as well. They too were great to deal with, especially Amber. Thanks again. I definitely recommend this company for anyone looking for HVAC services."

Air Conditioning questions, answered by experts

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 common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.
