"So many choices when your looking for a company to service your heating and air conditioning needs. When we reached out on social media for suggestions for a reputable and reliable company so many people highly recommended Advanced Mechanical Services that we wondered if it was for real. Well now you can count us among the believers. From the moment Deena took our phone call till Rob and Ian arrived at our home and completed the work on-site, these incredibly talented and professional people did their job on time, as promised, with courtesy and knowledge and quickly identified and fixed both our heating and air conditioning issues that three other companies that we paid big money to in the past could not figure out. Their reasonable bill for quality work was another surprise. And they were COVID compliant and respectful with masks AND gloves which made us feel comfortable (as senior citizens) having them come into our home to do work."

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

"We originally contacted Brian to measure, source and install window treatments on some skylights and windows, and when we found out he's a renaissance man, we asked him to do many other jobs for us as well--carpentry, electric, plumbing, labor & assembly, you name it. He's a consummate professional, easy to communicate with, and a pleasure to work with. He's such a nice guy I even invited him to stay for dinner one evening after he finished working. I'm not sure at this point what Brian can't do, but I'd trust him to tell me if something I asked for was beyond his wide ranging capabilities. We will absolutely hire Brian again and again and continue to refer him to friends in the future. The only challenge is that his schedule books up since he's highly in demand, so contact him sooner rather than later.
Some of Brian's work for us has included:
  • - Full-service window treatments for skylights and windows--we love them, and Brian's advice was helpful
- Repair of a slatted blind that Brian told us didn't really need replacing after all
- Selection and installation of a new blind to match others next to it--looks great
- Installation and assembly of 2 ceiling light fixtures. We didn't have the right part for hanging one from a vaulted ceiling, and Brian made sure to get one for us that fit the aesthetic perfectly. No corner cutting.
- Hanging pictures and heavy shelves
- Plumbing help with 2 leaky refrigerators
- Disassembly, strongman labor, and reassembly of a large piece of exercise equipment in another room in the house
- Window replacement
- Installation of a cat door through a sheetrock wall
- Installation of a track for a pocket door
- Installation of dimmer switches
- Assembly and installation of a large closet system
...etc. We've been happy with the results of all these projects--and all the rest that I can't remember at the moment.

FAQs for air conditioning projects in Harwinton, 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.
