"Mariano came out and prepared the estimate for my new furnace and air conditioner. He, his dad and brother installed both units, repaired some of the ducts and configured the electronic. All the while he kept me informed on the status. They cleanup nicely at the end of the day. Excellent to work with. I highly recommend their work and integrity."

"I called AT Mechanical to service my air conditioner. And I've got to say, it's like new! My AC used to not be able to keep up with the temp in the house. Now it easily does! Please give them a call if your AC isn't keeping up on hot days! I highly recommend using them to service your AC or furnace."

We would recommend One Hour Heating & Air Conditioning of Loveland, and would highly recommend Will S."

"Our furnace decided to stop working during a snow storm, we called damn near every service we could find, no one could get out to us for a few days - unless I wanted to pay an obnoxious fee. Just when we were getting ready to get a hotel, I found Halo. Not only were they able to come out quickly, but the gentleman was so kind, and respectful; Our 2 year old walked up to him and hugged his leg, and without skipping a beat, he put his hand down and naturally patted his back. He then checkes out our furnace to find that we needed to replace a fuse! SUPER EASY! We almost went days without heat and he (I wish I could remember his name) came out quickly and got our heat back on. All for a reasonable price! I will definitely be using Halo again."

"Tony did a great job replacing my broken 50 gallon self venting hot water heater. It is in a difficult space to maneuver getting the old one out and the new one in. He did a great job updating what needed to be done (in my old 1910 home so there is always something!) and I feel very confident in their work. Limelight is my go to place and am so glad I found them!"

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.
