"I needed quick service on a 45 year old hot water boiler in a 1938 house I recently purchased. While I could get the pilot light lit, nothing I did could get the boiler to fire (water was circulating).
On Wednesday I contacted Pelletier Mechanical as Gary (the owner) had been out giving me estimates on the various repairs and modifications I wanted to make. While Gary was out of the office training (again), Laura his admin arranged for Bill to come out on Friday. She provided an estimated cost (right on) and a 2 hour window.
Bill showed up on time and after a brief discussion get right to work. Bill spent about 15 mins. systematically determining why the flame would not light. He discovered that there the gas was not making it to the main control valve. He reset the safety shut off valve and the problem was solved. He then checked all the radiators to make sure that hot water was making it through out the house. After we determined that the upstairs radiators were not getting hot, Bill checked the water pressure and determined that the pressure was insufficient to fill the upstairs radiators in "real time". He suggested that the culprit was the 45 year old water valve and pressure release valve which being cast iron tend to corrode and clog in time. He proposed a replacement solution and priced it out, and offered to pick up the parts and replace the valves that afternoon. I decided to wait a few weeks so I could consider replacing the entire boiler.
While we were waiting on the boiler to come up to heat, Bill and I walked through the basement looking at the existing plumbing, tracing the water flow path and discussing the possibility of replacing the hot water tank with a tankless unit. (The hot water run is about 60-65 feet from HW tank to kitchen, bathrooms, etc.) Bill, like Gary, is knowledgeable and informative.
I will have Pelletier Mechanical back to do more work on the house."

"Arizona Rug Co. recently completed cleaning and restoring our rugs for us and we could not be more impressed with the quality of their work. The older and larger of the rugs no longer looks 42 years old. I recommend, as a designer, taking care of quality rugs in order to enjoy them fully. It also needs to be said that this company has a varied selection of rugs available from the well stocked showrooms, both in Tempe and Scottsdale, with knowledgeable sales staff."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"I don’t usually write reviews, but I felt like I had to for this one. I’d been dealing with an ongoing furnace problem for weeks and had a couple other companies come out but nobody could give me a straight answer or actually fix the issue. When Enea from Northeast Heating and Cooling showed up, he figured it out almost immediately. He was able to explain to me what was wrong in simple terms, fix the problem on the spot, and even made sure it won’t happen again. The technician was professional, thorough, and you could tell he actually knew what they were doing. After all the frustration I had before, their service was honestly a huge relief. Highly recommend them."

"Both of our AC zones had failed. The office staff went over and above to find us a service appointment slot shortly after we called in spite of their having a full schedule that went out 3 weeks. Tyler, the ECM tech, was very professional and capable. He immediately diagnosed the problem and had the system running at peak efficiency a very short time later. Great folks. Would definitely use them 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.
