"Great team! Mark, Sergii and Pavel replaced my furnace and installed an AC. It was a real pleasure to work with them. Mark listened carefully and provided several options for me to choose from. He was also flexible on scheduling the work to match my family needs. Sergii and Pavel performed the installation exactly as planned, kept the house clean, and payed a lot of attention to the aesthetics of the visible parts of the system. They explained to me where they'd run the lines, what were the options and why they preferred one over the other. I'm very happy with the choice of brand and model and with the installation. The team really cares about their customers. Thank you!"

"He came for our heater tune up. He explained to me how the furnace works and what he was going to do. Once the job finished he told me the repair to be done: to change the red sealer on the exhaust pipe to the proper blue sealer. He gave me the amount expected to pay for it and how long it should take. He is very polite and professional."

"Ricardo was timely and professional, quickly diagnosed the problem and hone in on the best solution. He is down to earth and know what he's talking about. He didn't push for irrelevant repairs or upsell me on more expensive solutions and just focused on fixing the root problem. Would love to work with him again."

"Jerry was awesome. Showed on time and got right to work. The type of ACs I have were new to him, so he had to learn them as he went. That first job took about 1.5 hrs. The next one took less than an hour. Near the end of the first job we got talking about other projects I am thinking about. I mentioned that I was thinking about getting my house painted (just in the investigating process right now no commitments" and that I had several estimators coming by in the next couple of days. He said "Oh, I do that too". Gave me a quote right then. When we were settling up for the AC installation, he gave me a written quote for the painting. $100 less than what he had told me earlier. Very satisfied with this first job and I will definitely be considering him for future jobs. Thanks, Jerry."

"Did a great job remodeling bathrooms and other projects we had. He is friendly and efficient. I highly recommend him."
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.
