"My technician, Lily, was right on time. It was her first time to my home and she was very friendly and informative. She explained what went wrong and also showed me how to maintain some things through my routine maintenance. My service call involved a charge as it was Service, labor plus Freon to be added to my unit and the outside unit's battery. Since I have a contract with McCrea, I was not charged for the part that was to be replaced on my unit. My house is slowly cooling down as it was 90 degrees inside my home when she arrived this morning. My house lost the air conditioning on the Fourth of July and on a very hot day. I would highly recommend McCrea Heating and Air Conditioning Services of PA."

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

"Turned on the AC this morning to find out was blowing hot air, called up a few different companies who wanted minimum 100 bucks to come out blah blah blah, called up Markool and got connected with a technician. The technician helped me troubleshoot the issue, and have me a quick fix that will last until they make it out tomorrow to do the permanent fix. I'll be using them for all my AC needs in the future!"

"We ended up totally replacing our heating and air-conditioning unit and everything we have done in the house has been through ET Lawson and under a warranty plan through them. We wanted the same thing. Nothing against Michael & Son. He seemed very knowable."

"Everything went well with our AC check-up. We would recommend Alder Cruz at American Air. He was professional, courteous and his services were reasonably priced. We've already made an appointment for the fall for him to check our heater."

"Last year, I asked this company to come take a look at a heat pump I had at a rental unit in Gettysburg. One of their technicians came out and according to my tenants, was there for less than a half hour. He recommended replacing the heat pump (which also requires replacing the inside air handler according to them). I was invoiced for this visit, and then contacted by the sales team. I talked with someone on their sales team about pricing, and they gave me fair and competitive prices on the inside and outside units. They did walk me through several options and were able to meet my time frame since I had tenants without AC in the hottest month of the year. Before spending thousands of dollars, I asked a friend of the family for a second opinion. He was able to repair the heat pump for under $350 in parts and labor. I paid him $500 for his work (since he saved me thousands!). I contacted Holztople's owner about my experience. They cancelled the invoice for the service call and sent me a certificate for $100 on a future service (which is great customer care in my opinion). It seems like they would be great to work with on a new installation. Be cautious with any tech from any company. Make sure they do their due diligence before they try to turn you over the the sales team. The heat pump is running fine almost a year later, and I have not needed to use the $100 gift certificate."

"Jim was very helpful and personable to work with. I had recently moved to the Huntsville area and was unable to connect my wireless printer. There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer. Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS. He was able to get the wireless connection to work as well. He took the computer on a Friday evening and returned it Sunday evening in prime condition.
A few weeks later I got an error message while reinstalling my accounting software so I called Jim. He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable. I will definitely use his services again.

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
