"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"We were having issues with our current furnace and decided to purchase new equipment versus putting repair money into an obsolete one. Due to the unreliability of the old unit, we wanted the new furnace/AC installed before we went on vacation. They arrived on time, and completed the work in the time frame promised. All the work was done to the highest quality, and exactly as promised. This work was done on a cold day, and with over a foot of snow around the house, including around the old air conditioner. With the cold temps, we were very happy the total job was done in about 6 hours. The equipment is working extremely well. TR Miller took away all the old equipment, and did a good job of explaining the operation of the new furnace, thermostat, humidifier, and air cleaner. I would highly recommend this company for any heating and cooling work.

"The man that came out was prompt . He fixed the problem for a fair price.i had a guy come out before him and he told me I needed a new system. It didnâ t make sense because my air system was just installed in 2018. I appreciate his accuracy identifying the problem. I have already reffered him to others"
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.
