"Joey was great about communication. He got back to me right away and was very knowledgeable. I needed my outside air unit replaced and the condenser inside. He was able to schedule me an appointment right away. When a part I needed was sold out, they went above and beyond to get it to complete the job on the assigned day. The installer came and finished all the work same day ever though he was behind schedule. Upgraded my air system beyond what I imagined. Everything looks great and I'm already savings money on my monthly bill. I would definitely recommend Iron Air for their service."

"Once again, Alex and his team at Renown AC answered the call at one of my investment properties. Tenants are happy again! Renown provided sound advice for the best fix in a timely manner at a fair price. There's a lot to be said for staying away from the huge AC companies and trusting in the quality of service Renown provides. Well, done Alex. Keep up the good work."

"TeamEnoch replaced my old air conditioning and heating systems, and the work they did was so good it borders on the unbelievable. Two very professional technicians showed up exactly on time, worked for 11 hours straight in really horrible conditions (a cramped attic in 95-degree heat) and did the whole job in one day! To top it off, their company’s price for all this was significantly lower than other estimates I had. This is a great company. I can see why they have won so many awards. *This review was migrated from an affiliated account on Angi with an original submission date of 10/4/2021"

"Lisa was responsive to my needs when my original HVAC installer stop responding after my initial install. She was able to trouble shoot why my system wasn't cooling properly, finally get my house cooled again. Lisa's commitment to 5 star customer service and competitive pricing are the very reasons you should call her today for all your HVAC needs. Thanks, Lisa!"

"I reached out to Florida Air & Heat Solutions from family recommendations, and they didnâ t disappoint at all! They provided excellent customer service, answered all my questions and they had the most professional service/ install technicians. I will be hiring them again for a new install in our guest house. Thank you again!!"
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.
