"They arrived on time. Responded with 3 personnel. They removed the old freon immediately and removed the outside and inside unit. It was hot and humid, but they did not complain. The attic is no place for a human in this heat. They prepared the site for the new air handler, installed it quickly and had the system up and cooling in no time.
A slight problem arose after they left at 6 PM in the evening, and they sent a very gracious and professional technician and in fact the installation supervisor responded, after hours!
They had the system running again, and found a faulty part was the problem, not their fault.
The next day they came back to see if the system was working correctly and even cleaned the area of the install more and they did not have to, they gave 110%.
I use and would use UGI for all my heating, cooling needs, they are excellent.

*** 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!

"They came out to give us an estimate, and gave us a very good presentation of the product they had to offer, complete with a demonstration of the features.
We ordered the door, and when it came in they called with an installation date and time of installation.  They arrived on time, and had it quickly installed.  They were going to replace the molding on the inside of the door, and because of our door being the original door when the house was built, the size of the molding they installed was too small and showed a gap between the door and the floor molding.
When I told them it wasn't acceptable that way, they called the office and told them what the problem was, and immediately were told to get the right size molding and install it.
The door looks great, and the glass is so much thicker and more sound proof than our old one.  We can feel a difference in  the warmth of the room with the new door, no draft and cold air coming in.  Overall, we couldn't be happier.  We would certainly use them again.

"The team effort was amazing to watch.  Along with the owner, the guys (Anthony and Joey) were impressive with their knowlege as well as answering my questions.  They were eager to answer and still kept busy with their tasks.  It has been a long time since I witnessed employees who not only cared, but worked extremely well together.  Newtown heating and A/C has a lot to be proud to perform in such a professional envoronment.  They are super.

Parts were made on site or in their nearby shop to custom fit the heat exchanger to my current duct work.  I am very happy with the state-of-the-art equipment installed.  I feel very comfortable with my new system and highly recommed contacting them.

The system has been working perfectly.  On 2/10/2014 I called about a message code and service was prompt.  The problem was with my internet service unable to download some new software as a result of the power outages from the recent snow/ice storm.

I am very interested in some additional work for a battery backup for my sump pump.  I am requesting additional information about a full home generator.

Also, they cleaned up after the installation and removed all of the old equipment.

FAQs for air conditioning projects in Herndon, PA

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.
