"We had an amazing experience with this HVAC company! From start to finish, the entire process was seamless, professional, and stress-free. Our AC stopped unexpectedly. They were incredibly responsive and able to schedule us quickly and arrive right on time. The technician Berto was knowledgeable, courteous, and took the time to thoroughly explain what was going on and what needed to be fixed. You can tell they really care about doing the job right, not just rushing through it. The repair was done efficiently, and our AC has been running perfectly ever since. It’s honestly such a relief to find a company that is reliable, honest, and truly skilled at what they do. We will absolutely be using them again for any future HVAC needs and highly recommend them to anyone looking for top-notch service!"

"I was looking for someone to install my ac mini split unit and placed a request on Angiâ s list. I received many responses even from large plumbing companies. Vladi was the most honest of them all. I highly recommend MVM Mechanical. Vladi is excellent, he explained everything that needed to be done during the consultation/quote (Pros and Cons). He did more and kept his quote. Itâ s a 5+ rating for me. I am definitely a long lasting client now."

"HVAC Repair A few days after our yearly inspection from our normal HVAC company, our ac began to struggle during a heatwave. Instead of calling back the same company, I decided to have someone else come take a look. Jonathan Hollins was highly recommended. Upon arrival he invited me to shadow him so that I could see exactly what he was doing. It only took a few minutes for him to identify the problem. While inspecting the outdoor condenser unit, he noticed that the fan was spinning backwards, and that the capacitor connections were reversed. After making the necessary correction, Jonathan continued to do a thorough check of our system. Thankfully, no other issues were found. Within a few minutes, we could feel the difference inside the house. I'm happy when my wife is happy. Also, the price was lower much than expected. I highly recommend Hollins Mechanical Services. He was very professional and more importantly, very honest and trustworthy. We plan to use him for any future needs."

"My central air quit during a nasty heat wave and they responded quicklyâ within a few hours a technician arrived that evening, followed shortly by the salesman when I decided to replace instead of repair. The job was scheduled for the very next morning! The installers were on time, friendly and cleaned up the areas. Everyone I dealt with was knowledgeable and professional. Interest-free financing was a huge selling point. Very good experience!."

"Ariel and crew were very prompt and detailed with what they were going to do with the boiler project. We had a really outdated unit that never could heat up the entire house (we have a basement, 2 floors, and an attic). Ariel was very familiar with the unit we had and what we needed in order to get heat throughout the entire house. He recommended getting a new boiler, and then replacing a valve and a pipe so that the heat would have enough pressure to circulate throughout the entire house. Im happy to report that we have heat throughout, with the exception of a few problem radiators that would need an additional part to be installed so that air can be expelled from them. We are still in the monitoring phase, but I'm satisfied with the results thus far. I will report back to this review with an update in the upcoming weeks."

FAQs for air conditioning projects in Pomona, NY

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.
