"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!"

"Mr. Duct answered my call for service and was able to schedule within a few days at a time that was most convenient for my schedule. They were very open about the scope of the job and the pricing and I was more than satisfied with the quote for the work. The service technician, Mario, did an excellent job. He worked especially **** ** the second floor ducts which were just filled with construction dust and dirt! He arrived on time, was very careful as he worked, and was not the least bit fazed by the condition of those ducts! He just got to work and made them shine! I appreciated that he took pictures and shared the before and after so I could see what needed to be done. He also cleaned out the dryer vent and the outside air conditioning condensers - all with a smile and a wonderful attitude. Mario clearly had a strong work ethic and kept me informed about the progress as he moved floor to floor. I will be scheduling a cleaning next year, likely in September, and will request that Mario return to do the job. The house just feels and smells so much cleaner and fresh! Thank you Mr. Duct (and especially Mario)!"

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"Tim Miller responded to my request for a bid on a new air
conditioner the very next day. He spent a considerable amount of time reviewing
my current heating and air conditioning system prior to putting together a
proposal, providing thorough explanations for the existing design and that it
was well done with one exception. The furnace had been replaced by another HVAC
company twelve years ago and they sold and installed an efficient 2-stage unit
but never enabled its 2-stage operation. Tim included correcting this issue in
his proposal.
I also explained the symptoms of the current system problem
and he suggested that the problem be diagnosed and corrected prior to
installation of a new air conditioner.
I received two proposals for the air conditioner replacement.
TRM's was considerably lower for equivalent units (American Standard versus
Lennox) and work. Once I informed Tim of my decision to go with his proposal,
he had a service man out the next business day to diagnose and resolve the
problem. Diagnosis turned out to be a little tricky and it required multiple
part orders and visits but in each case, Tim's service person kept me up to
date on the order status and immediately scheduled the service visit once the
parts were available. Tim's service person was friendly, prompt, and
informative. Tim also waived the labor cost for the diagnoses and repair given
that I had accepted his proposal to replace the air conditioner - you don't see
concessions like this very often.
With the furnace issue resolved, the air conditioner
installation proceeded and once again, Tim's people were excellent. They called
ahead to let me know their arrival time which was within the two hour scheduled
time, they were friendly and very informative. The installation was done very
well and was completed within the estimated time frame.
The bottom line is that TR Miller has a very professional and courteous
staff with years of experience. They did great work and I would highly
recommend them. I'll certainly be using TRM for my future HVAC needs.

"Mr. Talla did an exceptional job. I wanted an outside receptacle installed on my house and I am satisfied with the results. He also took time to explain to me about the electrical grounded condition of my residence and the importance of having it, basically, up to code and safe. I appreciate the advice he gave me overall regarding my electrical questions. I highly recommend his service."

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.
