"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!"

"Our AC was running however the fan wasn't turning. Pat came to our house at 8:30pm and started working on the unit--had it fixed within 20 minutes!
Fontana Brothers is the only company I trust for heating/air related issues. I've delt with so many companies and find that most of them want to charge an arm and a leg, then try selling you something on top of it. Fontana Brothers have always been professional, timely and trustworthy--prices are great too!

"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!"

"I’ve had a great experience working with Coolaire. Their technicians are always knowledgeable, kind, and communicative, making sure I’m informed every step of the way. The owner, Dave, is an honest businessman who has gone above and beyond, pointing out issues unrelated to HVAC that have saved us thousands of dollars. I highly recommend them for both their expertise and integrity."
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.
