"I called HomeAdvisor for heating repair; my furnace was not working and my thermostat was totally blank. I chose two of the businesses for an estimate as I thought I would need a new heating system. Bill from W. Gray Service called within an hour and asked what service I needed. I explained the situation and he asked if I had checked the batteries (I had not idea there were batteries). After changing the batteries, my thermostat worked and my furnace started up with heat. Needless to say I was very happy and will keep W. Gray Service in my contact list for any heating needs I may have in the futuer. Thank you, Bill."

"We have used Sure-Temp over the years from 2007 through 2011. They have done lighting upgrades to installing new ductless- split Air Conditioning systems to repairing our Carrier systems. They have always tried to make the most energy Efficient choices and have led us in good directions each time we have used them. We have spent over $40,000 with them for work over the years.
There was some warranty work to do on the ductless-split systems and it was handled well by Sure-Temp.
We will continue to use them in the future."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

"Mitchell Electric was very prompt and very professional."
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.
