"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."

"Very professional. Very Knowledgeable. The equipment is the best I've seen for the price. And I've seen a lot of them. Commercial and residential. I would not use anyone else. HVAC companies are not all the same. Believe me, I know. Have had years of experience overseeing Commerical HVAC contracts."

"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."

"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.

Their team did a great job and completed all the work in 8 hours! WM provides tremendous value and quality work. Highly recommended."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"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

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.
