"They were prompt and efficient, from the initial repair-person, to the 'comfort advisor' to the installers, as my system was ~ 20 years old, I replaced both furnace and AC."

"We have used Absolute Comfort Heating and Air for over a year now. Each time we have used their services, Shawn has been able to find the cause of the issues with our systems without having to order major parts or replace the old systems. Shawn and his team are professional, dependable, trustworthy, honest, and the ABSOLUTE best out there. We were so lucky to find these guys after years of having bad experience with other companies. They went above and beyond to ensure our family (with new baby) was warm in our home- (ie: they came out the same day that we called and made a trip after hours to fix another issue) so thankful guys!"

"Highly recommend! The air conditioner on my second floor was out. They were able to come check it out immediately. Rhett diagnosed the problem and had everything that he needed to repair it that day. I was even more thankful when I received the bill!"

"I called and Mike returned my call quickly and set up a date.  He came and checked the air conditioner.  He did not try to convince me it needed any else other than a check up.  Was quick and efficient and mannerly.  I would certainly use him again even for more serious repairs.

"I guess the price alright. It's about what we paid in Charlotte with another company, maybe just a tiny bit less. But I guess it's the what the prevailing rate is. We had somebody else to do the work, and they didn't do; and we paid them more. We have signed up to use them for our maintenance service for the furnace and air conditioner."

FAQs for air conditioning projects in Mooresville, NC

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.
