"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."

"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"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!"

"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."

*** I have recently added the Nashville area to my service coverage. Since I can do most of my services remotely with you over the phone, I am hoping to eventually open up to larger markets and help people from having to take their computer in to get it fixed, if it has internet access, I can usually fix it over the Internet. Just trying to do more to help my Angies List customers!!******** I am a sole proprietor that works out of my home. I am my only employee, but I have over 20 years experience fixing computers, and providing superior customer service. I work on a flat rate service, and don't charge by the hour because I feel it's important to educate the customer on what the issue is/was, and how to avoid it in the future. I feel that local service companies (my competition) have been overcharging customers for years. I offer a first time customer discount of 10% but I will offer 15% off for first time customers referred by Angies List. I've lived in the Huntsville area most all my life, so I know the area very well. I will never use a subcontractor as I am very picky about making sure that if my name and company is associated with something, it will be the best experience my customer has ever had, and using sub contractors won't ensure that, so I prefer to do all the work myself. Lastly, I should point out that I am a former offensive lineman for the University of Southern Mississippi and was Brett Favre's center his freshman year at Southern. I went on to play for Tom Landry in his last year, but gave up pro football early on to pursue my passion of fixing computers. If I didn't have bills to pay, I would do this for free because I love it! If you have a computer problem, I promise you that you couldn't find a better technician that will care about you as a customer, and not about the bottom line. I am always available, but don't always answer my phone, but if you leave a message, I promise to back with you as soon as possible...and figure out how to get your issue resolved in a quick, efficient and economical manner. Thanks so much for reading my ad, and I look forward to working for you!

FAQs for air conditioning projects in Big Pool, MD

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.
