Holtzople is a leading HVAC company in Frederick, Carroll, and Washington counties in Maryland, as well as Adams and small parts of Franklin & York counties in Pennsylvania, featuring all the top brands in the Heating and Cooling industry, such as Trane, Bryant, Lennox, Carrier, ClimateMaster, WaterFurnace, and more. We recently added an electrical department to our services, making us your one-stop shop for HVAC and electrical needs. Quality is Not Expensive, It's Priceless!

"Holtzople installed a geothermal system in 2013 to replace our heating oil furnace and electric air conditioning unit. Boy did that cut our heating and cooling bill way down! This review is about the recent semi-annual service maintenance visit. Shout out to Kevin the technician who is friendly, professional and focused. He gets right down to business and is quiet as a mouse as he thoroughly goes through the extensive maintenance checklist and performs all required tasks. He then takes the time to fully brief us on what he did what he found and what if anything he recommends. He then opens it up for questions and is very patient and thorough in answereing any questions we might have. Hint: he's also an expert on anything Disney World if you might be thinking about visiting there.... We highly recommend Holtzople, a great company, because they really do take care of us."

I’m Miles, and I have been in the electrical industry for 4 years. I have completed high school trade schooling and 4 year technical schooling. My best skillset is in residential wiring, including new construction wiring, remodels, troubleshooting, electrical panels, fixture installation, and much more. I’m also skilled in commercial work, such as bending and installing conduit, running MC cable, and working on three phase power systems. I work independently at a company but I enjoy doing work for people on my days off or in my free time. I have multiple clients that I’ve been working with for years, they’ve become more of friends than just people I work for. I enjoy my work and the people it allows me to get to know and help.

"Perfect. What a wonderful gentleman."

Heating and Air Conditioning questions, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

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.
