"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

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

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.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.
