"Excellent!! Bill explained the problem and gave me a price to repair. He ordered the part and came back in 2 days to fix as promised. I have used Blue Flame for the past 2 years for maintenance check up for furnace and air conditioning and have been pleased with the personal service that is provided. It’s a small business so the same person shows up for each appointment. The last company I used was larger and I had a different technician every time and didn’t feel like they knew me or my equipment. I have referred Blue Flame to family and friends"

"We lost our air conditioning the Friday before Mother's Day this year and I was scrambling in the heat to find somebody to cine and look at it. When nobody else would answer or would come out on Saturday, these guys did. Doug was great and he sent over Will and Rob for Saturday afternoon. Will and Rob are two of the best craftsmen that I have ever dealt with. They spent four hours Saturday going over my system and my setup and we talked budget, recommendations, the fixes, and schedule. By the end of Saturday, I knew that I was in good, competent hands. We agreed that the AC needed to be replaced, which was an 8 year old Trane (garbage). The furnace would be failing in the near future so we would replace that as well. They were going to completely rework my return ducting, which was shoddily installed by the original guy. They would replace my existing hot water tank with a tankless unit. They would install an automation system and replace a broken frost free hose bib. A lot of work. They were prompt and started work on Monday, worked all day Tuesday and Wednesday and came back on Thursday. They took their time, took care of my home and their work area, and most importantly, they took pride in their work. What they took out of my home was garbage and it was poorly and hastily installed. What they put in its place is great quality equipment and it was meticulously installed by two guys who take great pride in their work. While I am frustrated and unhappy that this situation occurred, I am glad that I hag the chance to work with these guys and this company. I will most certainly use these guys many more times."
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.
