"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

"I would highly recommend Prime Home HVAC. Our air conditioner was out for an entire weekend. I called Nathan on Monday, by Tuesday we had relief!! Nathan and his staff were professional and paid attention to detail. The price was fair and they made it easy. I love that they are a family-owned business. You will not be disappointed."

"Jay did great work, promptly, and taught me much about my older home's plumbing and HVAC systems. Installed new main service cut off valve, plus several other interior cut off valves for water lines to our two bathrooms, toilets and outside water spigot. All up-to-date and super easy to turn on/off. Plus, installed new Hot and Cold valves for tub in main bathroom that go with older style of tile and shower b/c originals had worn out and were leaking. Great to have this tub and shower available again for use! Did the work i requested, no pressure to upsell, but made some great suggestions for improvements at much better price than competition. Definitely will hire again and recommend highly. Thanks. -steve s. York PA"

"I thought they were on the high side. The only problem that I've had with their delivery is, they brought oil when I didn't think I needed it. If I have a full tank in April, I don't them to come out until the fall. I don't have to be here when they deliver the oil, they show up on the day. I don't have an appointment."

"Not only did they replace my old oil system with a heat pump, they replaced my entire AC system as well. Much more efficient, included new thermostats which are operated via mobile devices, and gave me peace of mind. Recommended an appropriate heating and AC system, replaced everything and did it in an efficient manner. Much more reasonably priced than all other quotes, prompt service & quick completion of the task. Didn't try to talk over my head about things that I wouldn't understand, explained it clearly and effectively. Highly recommend to anyone needing any type of heating or cooling repairs or replacements."

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.
