"Excellent! Joe and his staff were friendly, helpful and timely. They maintained COVID protocols for me/my family’s safety and went above and beyond to repair some unexpected issues. I also found cost to be very reasonable. 10/10...Plan to use them in the summer for my HVAC duct cleaning!"

"The guys were on time, cheerful, thorough, and and got the job done. They were thoughtful about my cat, too. The 'sanitization' stuff they sprayed did smell for a few days, despite my airing out the house with the windows open, but it did eventually go away. And they must have gotten a lot of dust out because my children (who are usually very sneezy with the dust pumping through our house) have seemed much better since the ducts got cleaned. Very happy with the service. I used an Angie's List "deal" for the service--I was in a hurry to get it done (my kids had dropped some art supplies down a vent that were making clicking noised that were driving me nuts) so I didn't compare prices at all, I just looked for a company that seemed thorough and they they were. And the clicking sounds of rogue art supplies is gone. Yay!"

"An honest assessment of my unit. Very thorough in understanding the unit and possible issue. Works fast. Should give a solid fee for service call, not $40-50. But was happy to give him the $50. Also, was given no paperwork to detail what he found or did with measurements of heat and cold air?"

"Needed a duo ac swap, nobody wanted to switch my moldy, leaky ac with a new one. I reached out to Mikey & he came out to NY and was able to do the swap. Job was done quick neat and stable. Would hire again for my homely fixes. Now I have heat for winter and ac for the summer. Thank youuuuu :)"

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.
