"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"Pete, Jake and Jeremy and a couple of other workers from Cool Heat Mechanical did a great job on installing 3 central air conditioners and air handlers at my house over a 3 day period. They were neat, clean, on-time and did an excellent job installing the American Standard A/C and air handlers. The units are running great and improved my energy efficiency tremendously over my older units. Pete is extremely knowledgeable with his profession of installing A/C and heating systems. His pricing is excellent as well. We are also using them to install a new heating system within the next few weeks. We initially met with Dave who reviewed their products and gave us the pricing for the job. Dave made an excellent presentation of all their products and did not use any high pressure selling tactics. He offered some nice financing options through EnergizeCT that I was not aware of as well. I did have multiple vendors competing for the job and found that Cool Heat Mechanical was the most knowledgeable and had the best products and pricing in my area. I did a fair amount of research and this company is the one to use for your heating and cooling needs. I highly recommend Cool Heat Mechanical for your HVAC requirements."

"i desperately needed gutter cleaning the day before a major storm. I spoke with Dave initially and he worked with me to make it possible and sent out his crew by the afternoon to my house. His crew was so professional and worked very hard to make sure that all the work was done for me and they cleaned up and got rid of all the mess. This company could not have been nicer and helpful. I highly recommend them and am thankful that I found their business."

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.
