"Kevin arrived today for the Spring Preventive Maintenance service on our HVAC system that we purchased a few years ago from Holtzople Heating & Air Conditioning. As always, we received an email and a phone call to let us know when the HVAC technician would be arriving. The Holtzople HVAC technicians are always very professional, clean, thorough, and polite and friendly. They are always willing to answer any questions we have, and their expertise and experience are evident in the excellent service they provide."

"Rob was the service technician who came by for check up on our Trane AC Unit. He was professional and courteous. He took time to explain and label damper settings for future reference. He was the best HVAC technician I have ever encountered thus far. Rob is definitely an asset to McCrea company. If I ever need service again, I want Rob to be the one to service my AC Unit. Thank you!"

"We got five different work proposals for our HVAC replacement. The person who came to our house was very technically knowledgable. He gave us his cell phone number and gave us plenty of his time answering our questions. I think this contractor would have done an excellent job at a good price."

"I had a gas leak issue and it was later identified that leak was on the outside of my house and Washington gas company fixed it. In the meantime I had approached Michael Bonsby to come and check if there are any issues inside my house. The contractor showed up and said that there is no issue with the HVAC and the pipes that are connected to the HVAC. He was suggesting that if there is a leak in the pipes that are inside the drywall, I have to contact a plumber. I wish the contracting company advised me that I may need a plumber in case the leak is in the pipes inside the drywall."

"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"We hired weather masters through Lowes. Adam Shapiro contacted us and assessed our needs. No drama around quote, gave us a competitive price and promised a quick install. As we were in sweltering heat with no AC , they installed a temporary window AC unit to help us tide over the next couple days, whilst we waited for the HVAC Lennox equipment. From quote to install was just within 3 days!! Everything was executed on schedule as planned and delivered as such. Shane and Steve are highly professional technicians who completed HVAC install within 8 hours. They cleaned up the area very well , tested the equipments and provided operational instructions. Highly recommend weather masters!!"

"Excellent service by MarKool. First it is a small company so when you call them you talk directly to the person doing the work. Second they are highly responsive. Third at the home they are very personable and answer all questions in detail. Fourth In fixing my problem they showed they are highly skilled and experienced in HVAC in this case as it pertains to gas furnace operation."

"The price was part of my check up I got. I just like that they seemed to want to talk me into having my air conditioning cleaned and it only been out there like 6 months. My interaction with them was fine. I told them no and so be it. The work turned out fine. They were fine."

Heating and Air Conditioning questions, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
