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 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

"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."

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

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
