It's improved but keep a eye on it and we will be in touch with a better solution. We also changed the rinse cycle to 12:00 during the day.

This option is designed to bring dedicated, high-efficiency comfort specifically to the second-floor Main Bedroom. We are proposing a Mitsubishi Single-Zone heat pump system. While this system is optimally sized to provide powerful, whisper-quiet air conditioning during the humid summer months, it will also act as highly efficient supplemental heating during the chilly spring and fall shoulder seasons.

Scope of Work

1. Indoor Equipment & Placement

Equipment: We will install a brand-new Mitsubishi wall-mounted ductless head in the 2nd-floor Main Bedroom.

Compact GX Series: Because the available wall space is tight, we have specifically designed this system using Mitsubishi's compact GX Series indoor unit. This ensures it will fit perfectly on the wall while still delivering exceptional performance.

Placement Details: The unit will be mounted to the left of the large window.

Controls: This unit will be controlled via an intuitive handheld remote.

I needed a new fan motor for my air conditioner. Jack replaced the motor and it ran for about 30 minutes and stoped. I called the company and explained what I had observed and they sent Mark out the next day to replace the motor and the same thing happened. They ordered a replacement motor from the air conditioner company, Mark installed it and problem was solved. This was all done very professionally and within a reasonable time period.Great company to deal with.

Jack is a very knowledgeable technician. He serviced my AC unit and found the fan motor was on its way out. He showed me the problem with the motor and had a replacement on his truck. Jack is very friendly guy and does not hesitate to discuss what he is doing and why. When he was finished, I received a complete report on items he had tested or inspected. I am Pleased he will be handling my HVAC system. Gina was also very helpful in arraigning my appointment.
