"I would like to recommend Robert from Wotton Heating for your next heating needs. Robert is an incredibly knowledgeable and pleasant tech. I recently moved to my first home and the home heating system was a huge concern to me so i reach out to Robert. As soon as he arrived he was educating me on how the system works and how to maintain it. He answered every question that i had and also provided me with local fuel distributors in my area. He did a great job serving the unit i highly recommend him. Thank you Robert!"

"I've been working with this organization for about 2 years, perhaps a bit more, they have always been cost effective until this recent experience, they spent ~30-45min here at the house and identified the problem as a clogged pan drain,
the charge was ~300, i asked why the "high" charge and it was broken down as ~250 to come out and provide service, and another ~40 for the cost of the gas "nitrogen" to clear the drain,
these people have always been polite, professional, and effective, but, the charges have now become cost prohibitive, if you got the money and need a someone, these people are the ones i would recommend
i did call the business and explained my concern, i was told the message would be forwarded

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.
