"I came home on a warm Friday early evening from work to find that our AC was not working. After making one call to another company who serviced our unit years ago and getting their voicemail, I waited a couple of hours then contacted my friend Maggi from Tyler. She responded immediately and the technician, Jonathan had the AC up and running by 9:30 the next morning. Thank you!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"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."

"We were referred to contact the owner Lou to install central air in our home. After speaking to him he came to our house within a few days to give us an estimate. He emailed us with a proposal the next day. Within three weeks our unit and duck work was installed and only took Lou two days to do. Lou and his electrician are very efficient, professional and did an awesome job! I highly recommend this company!"

FAQs for air conditioning projects in New Haven, 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.
