"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."

"Mike installed a new heating and ac system to replace my old system. His preferred brand availability and choices were clearly explained. His work was completed quickly and clean up was great. He was able to beat all other quotes for pricing and labor. He took extra time to double check the system. He also balanced out the air distribution inside in order to better cool a traditionally warmer area of the house. I would highly recommend him for any HVAC service."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"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."

Heating and Air Conditioning questions, answered by experts

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.
