"I have been using East Coast Comfort for heating and air-conditioning for years and I have always been pleased. They installed a new system for us years ago, did it for far less than other estimates we received, and we have reduced our energy costs because of it."

"Universal Air Heating and Cooling recently installed new air conditioner and gas furnace. Smooth process from start to finish. Bill was very knowledgeable and honest about what I needed. He provided options and did not oversell additional equipment like other companies. His team installed the new systems in a timely fashion. They too were knowledgeable and were eager to teach me. They were careful while in my home and cleaned any debris. Pricing of new system was very fair for Trane. Thus far, happy to use this company and would recommend to a friend or family member absolutely."

"The technician arrived early on the day of the appointment (which was the same day as the air conditioning going on the fritz). He diagnosed the problem, told me the cost and fixed it on the spot. He was very professional and informative and the unit has worked smoothly since. I would definitely use Unique Indoor Comfort again."

"We recently moved into a house built in 1987 with the original air conditioning unit, which constantly ran without stopping.  It was a brutal summer, but it was definitely not running properly.  Joe came out himself to take a look.  He took a look at the entire system and suggested that we service the AC to make it function properly and not constantly run.  He also changed the air filter in the furnace.  I appreciated the fact that he did not push a new air conditioning system in the house considering the unit we have is 25+ years old.  He also gave us a few ideas on how to make our home more energy efficient.  He did a great job.

"I met with about twelve hvac contractors as my project was a large job that included two systems and duct work. I met Erik last and he was the most straightforward person and did not try to up sell me. He painted the picture of what he would do and was confident in his proposal. When the work started it was smooth and detailed. Erik and his crew answered my many questions which helped me feel more confident. Overall a wonderful experience and value for your money. Erik included many items that other companies did not which helped the end product look and function better. Thank you!"

"George was awesome - our air conditioner stopped working at noon and he was here by 2pm and got us back up and running by 3pm. Showed me it was just the capacitor and also alerted me to a potential other issue down the road and gave me a quote on it just in case. Pricing was reasonable and I'm gonna use him for service on my unit and furnace as well here on out. I couldn't be happier or recommend him more."

FAQs for air conditioning projects in Exton, 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.
