"Tom was very knowledgeable he explained everything so I could understand. He did not try and pressure me into buying anything that I did not need. He told me my unit was old but it was still working good and blowing out plenty of cold air. When the time comes to replace the unit I will be calling Modern Air to get the work done"

"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!"

"I had called in 2017 for maintenance and to check the air flow. Brad did a cleaning and gave us detailed information on what was going on and his honest opinion on how long our a/c would last. He replaced a part on the compressor and told us to give them a call anytime if we had any problems. I decided to call them back this year again for a yearly check-up. Brad came again, friendly as can be, and looked at the air handler and recommended a replacement part but when he went outside he noticed the compressor was running extremely hot. After checking it out for awhile, he determined it would be best to replace the whole a/c. We approved to have it replaced two days later. The two techs who came out were very kind and cleaned up every bit of mess they made. They arrived promptly at 9 and were done by 1:30. This company is hands down the best to do business with. They don't give you the runaround and are all very honest and will not steal your money. If you need anything a/c related, call them. They get the job done and have great prices and warranties! They will always have my business!"

"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!

FAQs for air conditioning projects in Dunedin, FL

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.
