"Return Air Vent Move - Tech cut a crude opening in the ceiling framework which did not properly fit the elbow duct he installed. Did not clean up sawdust and did not replace insulation he moved. Displeased with the quality of workmanship of their technician. Repaired the sloppy workmanship myself due to time constraints for my construction addition. Bowman owner said I should have called back to let them fix it. Plumbing for Half Bath - Owner arrived on Oct 9th, 2018 to give me a free estimate to do the job. He did not like the fact that I mentioned the poor quality of the Return Air Vent Move job. After reviewing my half bath requirements, he left but never got back to me with a quote for the job. Called HL. Bowman approximatley 3 weeks later on Oct 29th, 2018 to inquire about my quote. Rep. said he couldn't find anything regarding my quote request. He said he would check on it and get back to me. As of Nov 1, 2018 I have still not received a return call or my quote; very dissapointing. Will not use this vendor for any of their services. Got a quote from H.B. McClure Plumbing to do the rough in plumbing; $2100. Will probably use them because I have been happy with the quality of their workmanship in the past."

"I hired northeast heating and cooling to replace my aging heating A/C system. This was a fairly large job, seeing it was a Multi floor house with two independent systems running both upstairs and the main floor. They also explained to me how adding a heat pump system to the house would help make heating my house less expensive during fall and spring. They replaced the entire upstairs duct work and reconfigured the entire house to run balanced and efficient. I couldn't be any happier with the work that was done in the house I would highly recommend them. Thank you Guy's for your hard work and dedication to get this system working amazing!"

"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!"

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.
