"I contacted Unique Indoor Comfort, among others, to obtain a proposal for replacement of my furnace and air conditioning system. Unique took measurements off all the rooms (for sizing calculations), answered all my questions, and provided me with a written proposal with several system options ranging in cost. Some other contractors that had estimated this job had failed to either take measurements or provide a detailed written proposal. Although Unique did not have the cheapest proposal for this work, I felt most comfortable choosing Unique for the job because of their professional approach to the work, their ability to answer my questions, and their well-detailed proposal. The installation took one day. The contractors wore booties and put down cloths to keep my carpet clean when moving equipment. The installation went well, and I was satisfied with the quality of the work. The only issue I had was that the installation team forgot to install an upgraded piece of duct work. This duct piece only affected the efficiency of the system, not the operation, but it was included in the contract and touted by Unique as a benefit of their installation. After I noticed this and contacted Unique, they apologized and sent someone to install the upgrade within a few days. Overall, I am very satisfied with the system and the installation."

"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."

"I was shown pictures of problems that I did not know was going on. I have had a heat pump in my Attic and I showed that mold was in and around my unit. I am thankful to James for showing me this and I was told about equipment that can be installed to make sure that we do not breathe this air that can come into our house. I got the repairs done today. I asked James to send me information about the type of unit that they can install to help with this problem."

"I was having some issues with my air conditioner and I needed my air conditioning coil and compressor replaced. It was replaced within a day and I couldn't be happier. The technicians who installed the unit were so clean and efficient. When they left, you wouldn't have known any work was done in the house. Everyone I have dealt with at Fahrenheit has been friendly, polite and extremely knowledgeable. I now have an air conditioning unit that works perfectly and am so happy I have found a reputable company to service my heating and air conditioning unit. I would highly recommend them."

"Just had AAC install a new central air conditioning system. Adam and John were both friendly and courteous. Very knowledgeable about what they were doing. Were respectful of our property and kept a clean work area. Excellent value for the money. They worked thru some rough conditions, bearing up with 150+ degrees in the attic. Would definitely recommend them and use their services again when needed."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

FAQs for air conditioning projects in Horsham, 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.
