"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 highly recommend to anyone in the Longwood or greater Orlando area Matthew Roberts Air Conditioning. They are an exceptional company that provides exemplary service. I recently had them install a new Trane air conditioning system and I was completely satisfied with the installation and service they provided. They are a family run business and you could tell they genuinely care about putting the customer first. Since replacing an air conditioning system is one of the biggest expenses homeowners face, I had several concerns going into the process and they made it a point to address all of my concerns and you could tell they wanted me to be happy at the end of the day. They didn’t try to upcharge me into anything I didn’t need as other companies did. My wife even commented that Luke Roberts didn’t seem like the other pushy salesmen we interviewed and was focused on doing what was needed. At the end of the day, I am thankful I trusted Matthew Roberts Air Conditioning with my new investment."

"Great. Fast response to my inquiry. The two installers did a good job. Left area so clean you would never know that insulation was blown in attic area. Price was good too. Thanks, JMS, we can really tell the difference in the air temperature."

"Service One has been wonderful to work with, both for our plumbing and air conditioning matters. Our A/C had 3 leaks in it, and Duke Energy failed to cover these damages despite the fact I had purchased a coverage plan with them. ServiceOne gave me a great quote and our technician Otto was super knowledgeable, personable and all around a great person whom we felt very confident with. I received another quote from Ferran that was nearly $1,000 more than what ServiceOne quoted, and for a unit that wasn't as efficient. The A/C is working great, they have a great warranty plan for it, and have always been very timely in returning calls in the past. Highly recommend them if you're looking for a good company that is trustworthy and will take their time to talk to you."

"I originally called my regular service company to come out and look at my ac and they told me I had a bad compressor and should replace my 7 year old system. I called Prestige for a 2nd opinion, and they said my compressor was not the problem. They also told me that my system was still under the manufacturers warranty. They repaired my system for under $300. I will definitely be calling them if I have a problem in the future."

FAQs for air conditioning projects in Sanford, 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.
