"This was my first time using Omni Mechanical and I am very pleased in their service of my oil fired boiler. I had recently purchased my home and had very little knowledge of any prior maintenance of the boiler. Other than knowing it’s an older unit I didn’t know what to expect of the internal components when it was opened up and inspected. The techs were nice enough to let me observe as they were opening up the unit and exposed the internals. So I could see for myself what they were talking about and physically see the condition. They walked me through what they were doing every step of the way. Taking the time to explain parts they needed to change and actually showing me the condition of the older parts as they were changing them. After all work was complete. Everything was left very neat and clean. This by far has been one of my most pleasant encounters with a contractor. I will definitely strongly consider them in the future for any work I need."

"I called Airwise after my former HVAC contractor diagnosed my furnace as having a seized oil pump. They quoted me over $1,300 to replace the pump and perform other services necessary to repair my furnace. They installed the furnace less than 3 years ago and this was the second oil pump that supposedly seized. Needless to say, I fired them. When Airwise came to repair my furnace, the tech showed me the pump wasn't seized and stated it looked like it wasn't installed correctly. After spending less than an hour putting the burner back together correctly, we had heat again. I will be calling Airwise for my future HVAC needs."

"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."

"i desperately needed gutter cleaning the day before a major storm. I spoke with Dave initially and he worked with me to make it possible and sent out his crew by the afternoon to my house. His crew was so professional and worked very hard to make sure that all the work was done for me and they cleaned up and got rid of all the mess. This company could not have been nicer and helpful. I highly recommend them and am thankful that I found their business."

FAQs for air conditioning projects in Watertown, CT

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.
