"I purchased a Deal, spoke with Ken, the owner, and he was flexible about my schedule changes (due to the tile job taking longer). Since a crew was running behind, he came himself to do the work late in the afternoon knowing that I needed the vent cleaning that day before we moved in. Ken did an amazingly through job of cleaning and disinfecting, and shared his knowledge about HVAC systems and duct routing the whole time. He analyzed our system capacity, checked the duct routing in the attic, and gave us options for improving our HVAC system in future when the existing equipment is ready for replacement. So not just a simple service - an informed future strategy! Can't say enough about how impressed we were with A Breath of Fresh Aire, we will definitely use their services again."

"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."

"Had service star Air & heating replace a 5 ton and 2.5 ton and two air handlers that had gone bad. Louis Ratti told me it would take his crew about 8 hours to completed the job from 9:am to 5pm. The crew got there on time and started to work right away. They were professional, courteous and proficient. There was no guessing to what they had to. They were good I say better than good. By 2:30pm they had both systems up and running and the work area clean and spotless. Not only that, I asked if they would connect my phone to both thermostat and with out hesitation they did it. I was very highly impressed. Thank you Louis for sending the right crew"

"This company is top notch. They did a two system retrofit in my home with 5 ton and 3 ton communicating Amana products. It started off with Wes the owner coming on a Saturday to have a look at the job and his recommendations and price. He really seemed like he knew what he was doing and was knowledgeable. Well it turned out to be true. The proposal was fair and he had the best price by far for this type of system. Then the actual install took place. The installers were prompt and the install was very clean looking. They were very careful in my house as they had to get one of the air handlers out and into the attic space on the second floor. When they were finished you wouldn't even know they were there, they left the place so clean. They showed me the work they had done and explained the thermostat settings to me. Overall I am 100% satisfied. Would highly recommend the Amana products and Wesley Whitson. The air conditioning itself is amazing as well. Quiet and comfortable."

"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 Lake Mary, 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.
