"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"Excellent customer experience from beginning to end. Alex was very professional, honest, and not aggressive for my business. Huft provided $4,000 in rebates and a $1,600 promotional credit for an electric HVAC system upgrade! The installers were prompt, expedient, and considerate to not make a mess. The workmanship was great in the interior attic and for the exterior condenser. They cleaned-up afterwards and left no trace or trash. They even ran diagnostic tests after installation and provided the written results with follow-up 6 months later to inspect and make any adjustments. I would highly recommend Huft Heating and Air Conditioning for a new HVAC install."

"Overall, the project went very well. They did push our initial installation date back by 3 weeks but once here, they put in the hours to get it done in a timely manner. I especially appreciated the professionalism of Keith, Pedro C and Kody M. They put in 2 new units with new duct work to fix the balance issues that we were having in our 3200 sq ft home. Now, the temperature in our home is consistent in the various rooms which has been a problem over the past 20 years. Keith said that the project was underbid by error but they stuck to the quote that was given to us. We had several men from the company working on the project. By far, Pedro C and Kody M stood out and were top notch paying attention to detail and cleaning up after themselves on a daily basis. It was very hot and they stayed late to make sure that we had air conditioning over the weekend. The bottom line is that they did not cut corners and were neat and professional and most importantly delivered on their promise to give us a system that works well. I have already recommended them to 2 of my friends/family."

"Matt arrived on time & fixed duct leak above furnace & water tubing to drain water reinserted & glued. Also got 2 ceiling filters for me unasked & put new filter in. Very reasonable price for labor & supplies. Previous Dependable Heating & Air company sent 2 people who insisted I replace entire furnace and ducts up to roof vent & wouldn t fix simple duct water leak. Admittedly my furnace is old but still working fine. Will never use Dependable again. Matt didn t pressure me to replace furnace & give me a quick $ amount with no pressure. Nice guy. Matt Kazen was wonderful & will definitely use his company again for heating & air conditioning needs."

"From our first conversation to finishing my Heating project, Comfort Home Heating and Air was full on fabulous. Juan knows his trade very well and led me through my questions and decisions. Once we agreed on the project and date, Comfort Home showed up on time and seemed to use every moment effectively, by being Systematic and organized. They cleaned the area around the Heating and Air unit so it looked better than before. I can tell by looking at the installation that things were done thoughtfully and cleanly. I have worked with many contractors and have never come close to the satisfaction... even pleasure I had with Comfort. I cannot think of anything Comfort Home Heating and Air could have done better. I highly recommend them, if you want the best."
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.
