"Everything went well. Rodenhiser handled all aspects including obtaining an interest-free 7-year loan, installation of heat pump/air handler, coordination with town inspections, and submission of rebate claim. I would recommend them highly for this type of project."

"I've been working with this organization for about 2 years, perhaps a bit more, they have always been cost effective until this recent experience, they spent ~30-45min here at the house and identified the problem as a clogged pan drain,
the charge was ~300, i asked why the "high" charge and it was broken down as ~250 to come out and provide service, and another ~40 for the cost of the gas "nitrogen" to clear the drain,
these people have always been polite, professional, and effective, but, the charges have now become cost prohibitive, if you got the money and need a someone, these people are the ones i would recommend
i did call the business and explained my concern, i was told the message would be forwarded

"Great service from start to finish. I needed a last minute service to install a range microwave mounted above my stove (option wasn’t listed above for service) in replacement of one that I had poorly attempted to do myself. She responded quickly to my inquiry, was on time, extremely friendly and got the job done quickly. All beyond my expectations."

"Tito arrived early. Was kind and professional. He immediately got to work and wanted to try to see if he could fix the broken fan first, but when he could not, he got the old one out and new one installed in no time. Arrival to departure was an hour and twenty minutes. He was knowledgeable on how to do the replacement and was a trooper taking care of the replacement in the hot attic. We purchased the fan for the project and Tito was so helpful in advance helping us figure out how to measure the old unit so we could buy the correct replacement. Will absolutely have Tito back for more repairs and projects."

"I recently had an old deck removed and replaced with a stone patio. The portion of my house where the deck previously contacted my house needed replacement shingles. Despite rainy weather conditions the day of the job, Bob was able to get the job done. I would highly recommend him."

"Iâ ve been a project manager for a few years, and worked with several different companies. However St Joseph Heating And Cooling stands out from the others, not only for the quality of work and professionalism, but also for the business culture itself. The company takes their time to go over the work and educate their customers. A very noble and caring way to do business. I highly recommend this company for its integrity and outstanding customer services."
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.
