"Our furnace started shooting out cold air very early morning in the midst of winter. Evergreen responded first thing the following morning (my request for repair was put in about 4am) and was the ONLY company of 4 requests to respond. They were able to get a technician out the same day for emergency repair. Todd arrived within 2 hours of confirming the visit. The company even sent a text with an image of the technician for safety purposes (this is extremely rare). He was able to diagnose the issue quickly and come up with an affordable fix that would keep the issue from recurring. He had to reroute the drain pipe that had frozen and backed water up into the system … had everything he needed in his truck and was finished within two hours of his arrival and found a solution that was affordable, quick, and professional looking. Before leaving, Todd gave us a mini lesson about the furnace so we can do basic maintenance ourselves in the future. (This is our first home, this furnace was already in place when we bought the house, and we had no experience with these types of systems.) Also gave us some reassurances regarding our natural gas system. I will definitely use this company in the future and would recommend to anyone having furnace issues."

"Clearwater Construction services was a great company to work with. CJ was attentive and communicative which is hard to find in this business. Every person that came out was polite and cleaned up very well. The subs they used were top notch and I would use any of them again. They did what they said they would do and did it on time. We were so impressed how they cared for the house while working on it. They treated it like their own. I highly recommend them for any work they can do and I will use them again when needed."

We pride ourselves on being the source for all of your HVAC needs. We not only design mechanical systems, we install residential and light commercial new units, and can retrofit and upgrade your older unit as well. Whether you need to replace a furnace, single rooftop unit, ductwork or a total system upgrade, Andersen Heating, Inc., has the experience and capabilities to provide the right solution for you.


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.
