"My furnace went out unexpectedly, and Steven was over within the day to give me a detailed quote. He came prepared and had already conducted his load flow analysis prior to arriving and already knew what I needed. He also offered a very competitive quote, and furthermore offered and ultimately installed the unit himself to get us up and running ASAP. With Cozy home solutions quick response we had a new furnace up and running less than 2 days after the old furnace went out. I am extremely satisfied with the entire process and recommend Cozy home solutions to anyone with heating & cooling needs. Always happy to support local business as well!"

"Our a/c stopped Friday night of 4th of July holiday weekend. While we were out of town! We found out our regular company didn't even have emergency service. We found Zach from a referral. He came out and diagnosed the problem. He was very thorough, thoughtful about options and while he couldn't fix it that day due to circut board not being available and warehouse closed, he came asap the first business day the warehouse was open after he got the part. He advised us during the whole process with difficulty reaching us from spotty cell phone coverage even using text. He was very friendly and exceptionally communicative. He is our new go to guy for all our needs!"

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.
