"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, and I do not have all the required tools, 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). The freon compressor in the old system had a short circuit to the ground, but because of the R-22 phaseout I had to replace the entire system rather than just the dead compressor. I contacted 13 companies that work in my area. 9 of them told me that they were very busy and could not take new orders. 4 companies sent salesmen who gave me price estimates. Three of the four price estimates included items that were not necessary, which is what pushed the prices up. When two people (Debbie Thomas and Ron Thomas) from Maryland Heating and Cooling showed up, they started to discuss with each other (in my presence) which items I do not need to replace; this 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 freon lines are in good shape and can be re-used, all the wiring and fuses need not be replaced, and the old thermostat is perfectly fine. 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. And they were completely honest with their price estimate. I was very impressed. I can recommend this company."

"The inspection went extremely well! The HVAC technician, Mike B., was extremely professional, arriving within the set 2 hour timeframe, even calling me within 10 mins of his arrival. I had a list of questions for the technician and the technician happily answered all of my questions along with showing me how to change the filter on our system. The technician explained the services that Grove Heating and Cooling offers without any pressure to purchase future services. We liked the service so much that we signed up for our next service with Grove Heating and Cooling, receiving a great discount off the flat rete price of $125."

"I have nothing but kind words and gratefulness for this company. I am a senior citizen who lives alone. On 21 Jan (the day before) the snow storm, I awoke to no heat in the house (which is an old house). Got on Home Advisor hoping I could get immediate relief but realistically knowing what the odds were. I quickly received phone from John and told him my misfortune and he came right over to take a look. Bottom line, he and his crew of guy removed and installed a new HVAC (which I knew was coming) for what I considered a reasonable prices. Those guys literally saved my life. I would high recommend them to everyone. They are highly professional and get the job done!"

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
