"We have an older home with older ductwork. We had Spencer and Brayton out and they cleaned and sealed our ductwork. They did a great job. Professional, great communication, attention to detail. They reduced our air leakage by 86%. We noticed an immediate difference in improved airflow, our cold spots are no longer cold spots. Thanks!"

"CandK was focused and diligent. They are based in Ames where I live. They were punctual and available when I had questions. I was offered a free Carrier Wi-Fi thermostat. I accepted. Installation issues with the powered "C" wire made me switch to a different thermostat. They handled all paperwork needed for rebates, and for a tax credit for the 2016 return. They have decades of experience. They know installation, and I chose them because I trust they will be in business for the life of my Carrier furnace and air-conditioner. The Dynamic air filter is the best filter I have ever seen in a residence. I just spoke with them today about also installing a new Rheem gas water tank to replace my existing tank."

"First, this company has handled all of my heating needs/problems since 1986 when they replaced a 58 year old gravity furnace with a high efficiency forced air system. I was not always pleased with this first furnace, but the company techs always gave me good service and advice. I needed to replace this furnace due to a flooded basement that left the unit under water for 6 hours and it was 23 years old. I looked to Home Energy Center (HEC) because of the good service they had provided over the years, but it was their job to lose - I had some questions about the old furnace. I called to make an appointment for an estimate and Kevin came out on the date and time of my choosing (at that time as late as 7pm and Sat. available). Kevin knew about my old furnace and told me they had stopped installing that model a few years after my purchase - they had found something better (I believe mine was an early high efficiency model -92%), I was impressed that he didn't try to sidestep any of my criticisms and presented me with what I thought was a good heating plant. Kevin said it's normally a 2 week wait for the installation but they had a cancellation the following Monday (4 days) and if I opted for that date they would deduct $250. He already had my business so I thought this was a nice gesture. That Monday the 2 installers came at 7am sharp and got right on the job. They said it would take about 8 hours so when I came home at 330pm I was surprised to find they had finished up and left They did leave all the manuals and instructions for operation. HEC provides what they call a "happiness check" where a company rep makes a return visit to check out and familiarize the homeowner with the system. I called Joyce and set up this appointment for a week later and Steve arrived at the appointed time. He had a checklist of items to go through with me and answered all my questions. He again covered all the warranty information and said I would receive materials in the mail to apply for an energy rebate and the Federal Energy Tax Credit (2010 exp). I did get these documents as promised along with excellent instructions in dealing with them (thanks Joyce). Granted I have only had this furnace for 2 months but so far I have no complaints and the house is warm. I would certainly use HEC again and will for future service/maintenance calls."

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.
