"We choose Unique Indoor Comfort as the company to replace our 1960’s era gas boiler with a 83% AFUE Weil McLain, and we’ve been very happy with that decision. Everyone from Unique that we interacted with was professional, personable, and patient. The latter quality being reflected in the willingness of everyone from Unique, from the salesperson to the installation crew, to take time to answer all our questions. After sizing our heating requirements, Unique presented us with several packages, of differing efficiency, that included boilers smaller than the old one, but ones that would meet our heating needs. This was in contrast to other companies that wanted to replace our old boiler with one of similar size, not taking into account that the old one was oversized to begin with. The Unique package we chose included outdoor reset, and air elimination, items that may have increased upfront costs, but ones that will probably offer savings, convenience, and increased comfort in the long run. Some other companies didn’t even mention these options. Thank you to Dante, Taz, Sam, Jameel, Brandon and all the Unique team, for making our boiler replacement project an excellent experience!"

"We recently moved into a house built in 1987 with the original air conditioning unit, which constantly ran without stopping. It was a brutal summer, but it was definitely not running properly. Joe came out himself to take a look. He took a look at the entire system and suggested that we service the AC to make it function properly and not constantly run. He also changed the air filter in the furnace. I appreciated the fact that he did not push a new air conditioning system in the house considering the unit we have is 25+ years old. He also gave us a few ideas on how to make our home more energy efficient. He did a great job.

They made sure the property was kept clean during and after install."
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.
