"Ken arrived promptly on a Sunday afternoon to repair my air conditioner that was not cooling. After having a negative experience with another company earlier in the day who tried to scam me into buying an entirely new $9500 system, Ken was able to diagnose the problem and fix it on the spot for a fraction of the price. He was professional, thorough, and explained everything in detail. I highly recommend Ken and A Breath of Fresh Aire, and I won't hesitate to call them for my future needs!"

"Last night my air conditioning stopped working and I called Bayside out to help me. It was after hours and I was worried that it would cost me an arm and a leg not to mention a service tech with a horrible (after hours) attitude. But I was pleasantly surprised when it was the same cost as having my pool serviced (in the daytime @ normal hours) and my technician had an upbeat attitude! He found it was a capacitor so he replaced it with no issues and a smile and now my A/C runs like a charm! I really like the folks at Bayside and I will tell everyone I know how great they are!"

"The owner of this company was very responsive and timely. He came very quickly to do an estimate and provided a quote later that day that was very detailed. The work was done on happy day it was scheduled and completed diligently. I estimate included a 3 year maintenance contract and 10 year warranty for parts. This was not included in the other estimates we received. We now have a brand new air conditioner with some new duct work and are very pleased. Another company Davis and outrageous estimate for $7000 more and the company we chose said they could not possibly come up with enough whistles Bells and gadgets to arrive at an estimate so much higher."

"Kevin was professional and extremely diligent. Our air conditioner broke during a streak of 85degree plus days. The closest replacement parts were almost 50 miles away. Kevin drove up and back in the rain, returning after 7:00 pm to ensure we had air conditioning."

"I've had them out several times. If they find any problems, they let me know. I use one of their technicians named Hank. He is wonderful. We had problems in the past with air conditioner guys coming out and mess things up. We had Hank come out and he is one of their best technicians as far as I'm concerned. I will only have Hank come out. I don't want anybody else servicing my air conditioner. They are very, very fair. If I had an issue, I had called about something and they worked it out pricewise with them. Hank is superb. He is consistent. He's very good about bringing up issues. I just entirely trust him. They are very good. If I call with a problem, they are out here within the day. They are very, very punctual. When I call for an appointment, the girls are very, very professional. I've called and everyone has always been very respectful. Hank is very respectful."

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.
