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."

"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

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

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

HVAC systems last around 10 to 30 years. If you complete the recommended maintenance, you can expect your system to reach its maximum life span. The life span also depends on the type of HVAC system. Heat pumps last about 10 to 15 years, AC units last about 15 to 20 years, and furnaces last around 15 to 30 years. Boilers have the longest life span, as they last around 20 to 30 years.

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.
