"We had an outstanding experience with Holtzople Heating, Air Conditioning & Electrical Services thanks to the excellent work of Andrew and Jake. From the moment they arrived, they were professional, courteous, and clearly very knowledgeable. Andrew and Jake took the time to explain everything they were doing, answered all of our questions patiently, and worked efficiently to get the job done right. Their attention to detail and commitment to quality were obvious throughout the entire process. Our installation was seamless and we are very pleased. It’s not every day you find staff who combine technical skill with great customer service, but these two really delivered. It’s clear that Holtzople hires top-notch staff, and I wouldn’t hesitate to recommend their services to anyone. In fact, we are now repeat customers and have used Holtzople for additional services. Thanks again to Andrew and Jake for a job well done, and Holtzople for providing excellent products and services!"

"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

"Our whole furnace broke and in within 48 hours we had a brand new one for a great price and ready to go before the winter. They worked quickly and efficiently especially with me having a little one running around. I would highly recommend them to anyone. Having a huge appliance break right before the cold weather comes was stressful and they did their best to make sure we didn't go without heat in our old house. Thank you for taking care of us and 5 stars hands down !"

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

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
