"Temperature Control is our go-to company for air conditioning and plumbing. We purchased a central air unit from them almost four years ago. We have never had a problem with it, and we regularly have their system check-ups to keep it serviced properly. We just had a plumbing emergency, and they sent Manuel Valdez out to fix it. He was great. Mannie showed up quicker than we expected and worked far more than he should have had to, but he was determined that it be perfect. It is nice to deal with a company that leaves you feeling like you got your moneyâ s worth."

"My A/C unit was blowing hot air out on Tuesday 4/15 and I called Dynamic Comfort who installed it that afternoon. On Wednesday 4/16 Will came out gave it a leak test and determined that I did in fact have a leak and he gave some refrigerant to last through the night which it did. On Thursday 4/17, Brandon came out and found the leak, but that was not the only problem, he stayed here for around 5 hours until he found the problem, which was a bad pipe that needed to be replaced. Brandon did a very through job in finding the problem and he wasn't going to leave until the problem was fixed. Dynamic Comfort has always provided me the most excellent service and this was another prime example. Kudos to them and their technicians Will and Brandon!!!!"

"They showed up same day I made the call. They are very expensive. I paid $192.00 to correctly attach the air vent on top of the water heater. He did not use new parts. He used the same parts I had already. All he did was expand the vent with a pair of pliers and reattached it to the water heater. Too expensive."

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.
