"We had 1st Action Plumbing, Heating & Air Inc install a new furnace and A/C system in our home about three years ago, and we couldn’t be happier with it! The system has worked amazingly well and has been reliable ever since. We had a great experience with the installation and would definitely recommend 1st Action to anyone looking for quality HVAC work and a company they can trust!"

"Heart is absolutely amazing! Look no further, as Heart is who you should choose to work with! They are very professional, punctual, and do everything right the first time. We have a couple of different areas Heart helped with, and so this review focuses on the HVAC work we needed, beginning with replacing our rooftop package unit. Every single person is phenomenal to work with, and very knowledgeable; starting from Mike setting up the appointment, Roberto coming out for the diagnostic, and then the multiple teams with Cody, Blake, Steven, Collin, and Cory working to get our unit replaced! I know it was much more involved than initially thought, and these guys were here doing all that they could to get our heat up and running again! They offered us heaters to keep us comfortable, and communicating and explaining what was going on every step of the way! We had an issue with the filter, and so Steven, Collin, and later Cody, came back a different day to create larger return vents for us to be able to replace air filters inside our home. They helped us so much, and removed shelving that was in the way too! We also needed our electrical panel upgraded, and so Cory will be helping us with that (thank you Cassandra for getting that reschedule). Heart also was able to have all of what we needed financed under one bill, which was a huge help! I cannot imagine going through the HVAC and electrical replacement with anyone else; these guys made it easy on me and kept my stress level down. My only regret is not having found them sooner back when we needed our water heater replaced. We will definitely keep Heart for any future issues we have, and keep with the membership program to have areas checked out regularly. Thank you to everyone at Heart--you all are truly amazing and we appreciate you so much!"

FAQs for air conditioning projects in Fort Lupton, CO

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.
