"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"The units are nice Trane high efficiency. The installation was quick and painless. AFTER, not so much: 1. Was told these units would work with my Nest Thermostats (V2). Upon completion of install, the installation folks couldn't get the AC to switch on. Only heat. They asked ME for documentation on the Nest Thermostats. Then I had to call Nest. Then THEY would talk to their lead service guy. Heard nothing..I ended up having to buy two new Honeywell thermostats to work... 2. Upstairs AC stopped working 3-4 months after install. We turned it off, waited an hour, turned it back on thinking the lines froze (common with our old Goodwin unit). It worked, but I called service to come out and check the unit. They mentioned something about freon being a little low, something about a switch that MAY be bad (didn't replace, didn't do anything)... Now I wonder if this unit fails after 1 year I'm now stuck paying for labor when it should have been fully diagnosed and fixed NOW! 3. Noticed alot of water building up around the AC exit tubes in crawl space. During routine spring maintenance, found two drain tubes thrown into our shrubs from the old system - Comfort Air NEVER PUT THEM BACK ON! Called immediately. Original time was 1-6 PM, no call until 10:15 PM where I was informed that I had to reschedule. Poor! Called the next morning, guy came right out. Put on the drain tubes. 2 weeks later, tons of water still! Took a bit to get someone to reach back out to us, but today (8/4) they came out and HOPEFULLY got them installed correctly. Not sure what kind of damage has been done to our foundation from the glaring error on their part. I would rate them a solid C. However, they are moving lower and lower over time with things that just weren't done right to start."

FAQs for air conditioning projects in Knightdale, 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.
