"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"Toilet re-install because my DIY install caused a ceiling leak. Horizon Services charged a reasonable $376 (with discounts). My only concern was 1 of the 2 workers was not Covid vaccinated. My wife and I are 72 yrs old vaccinated with co-morbidity issues. ALL businesses should notify customers of the COVID vaccination status of employees working in customers' homes. I WOULD RECOMMEND THIS BUSINESS FOR THE WORK. But, they need to amend COVID policy. Once vaccines recive full FDA approval ALL business must require COVID vaccination as a condition of employment."

"Andrew replaced our heating and cooling system and went above and beyond. He ran into a lot of faulty wiring from the previous installation and made everything right so we have a safe and functioning unit. He worked long hours to get the job done quickly as well. Thank you Andrew! Totally recommend and will continue to use him and his company."

"Turned my furnace on, and cold air blew! Looked here on Home Advisor for a top rated pro, and called Unique. They were here within 2 days (it was not that cold out, so it was not urgent). Joe was thorough in is investigation and was kind enough to explain everything he was doing, so I understood. He did not have the part to fix it right then, so they had to order it and come back. He and Rico came back for the repair and both were very nice and knowledgeable. I feel confident with their work, and they were a pleasure to deal with. I feel the price is a little high, but they warranty their work and seem to have very skilled workers, so I think it is worth the peace of mind. Also, all the office staff on the phone were great to deal with as well."

FAQs for air conditioning projects in Telford, 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.
