"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."

"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."

"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms. I would highly recommend him to others and have given his card out to friends and family already."

"These guys are the best. we moved into a new house back in June and had the hot water heater die after a few weeks. Frank was out the next day with a new hot water heater, at a excellent price. Both my wife and I were extremely happy with the work done, the price we were given and the customer service we got. Since then we have had two other 'emergencies' (air conditioner/leaky pipe in bathroom) and these guys came out right away and fixed the problems at excellent prices. Each time we had them at our house, they were very detailed about what the problem was and how they were going to fix it. Our HVAC is 25 years old and on it last legs. We've already asked Frank about it, and as soon as we are able to, we'll be calling Old Skool for our new one."

FAQs for air conditioning projects in Lancaster, 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.
