"Started noticing the house getting warm at 4;30 on a Sunday. Called Modern Air because they had come out two years ago and got out 13 year old system running well. He was here within the hour, fixed the problem and charged a very reasonable price. If you need air conditioner service or a new unit, call Modern Air!"

"Ken came out originally to do some duct cleaning but noticed that a lot of our supply and returns weren’t sealed properly with mastic (he showed us the areas that needed work). He came back out and sealed all the ducts, installed an air purifier and cleaned and sanitized all the ductwork. He was polite, knowledgeable, professional and hard working. Definitely recommend his services."

"After a leak the a/c would run but not cool off the house. We were very fortunate to have someone come out right away and address the problem. Parts needed to be ordered but they managed a temporary fix to keep the house cool and comfortable. They showed up in a timely manner once the parts were available and everything has run smoothly since. D&W is always polite and professional. I highly recommend them to everyone for a/c purchases and repairs."

"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!"

"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."

FAQs for air conditioning projects in Largo, 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.
