"I was really worried I would have to go a few days or even a week without cool air, but I called Dayco Systems that my friend recommended and I'm SO glad I did! They came out right away, after hours and fixed the unit. I highly recommend this company!"

"Richard Eppers, the Owner and President of Guardian was actually the technician who serviced my air conditioning unit. He took time to explain how he was going to proceed, and as a senior sheltered during the pandemic, was relieved when he did not enter my home before putting on his mask and covering for his shoes. He found and fixed the problem in a relatively short amount of time, and offered advice on temperature control and future maintenance. Richard was very courteous with being phony, showed genuine concern and was totally professional throughout. In the end we discussed a maintenance agreement, which I decided was the appropriate route to avoid any future "surprises". The agreement was reasonable and I strongly feel, that though had no previous knowledge of this company, based on the Owner, that future technicians will just as professional and knowledgeable. I could not have expected in customer service, from my first call in and expeditious scheduling and followup by the office staff, to the completion of the call by Richard, I would highly recommend Guardian in a heartbeat!. I fully expect any future technicians to show the same professionalism and expertise as their boss."

"Good company. Good experience from the time I began obtaining an estimate, until the work was completed June 2016. Prices were fair and reasonable for above-builder-grade product on 2 (Carrier Performance Series) HVAC unit replacements. They were very accommodating on meeting the timeline promised. My ONLY issue was that a bit more care could have been exercised on the install... but it was hotter than Hades, making conditions brutal! I am choosing Ragsdale to continue to service our units. I give them a A-"

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.
