"Alex from Green City was on time for the scheduled maintenance of our ductless heating/cooling unit. He was personable, professional, and explained thoroughly what he was doing. Last October (2025), we had to replace our ductless system (installed by a different company 7 years prior) and we chose Green City to do it…and we’re and are very happy with their work and responsiveness. I highly recommend Green City!!!"

"Everything from the information about the furnace and heat pump to installation was done in a professional manner. The installers were prompt and courteous. Before they left they explained how take care of the filters and the thermostat. It was not the cheapest bid but I have been dealing with this company for many years and felt comfortable going with them. I would recommend them to anyone who needs a new furnace or heat pump."

"With freezing weather on the way, it was time (past time) for maintenance service on our 10-year-old gas furnace.  After much research on the List, I called Pacific Air Systems because of their positive reviews.  The office staff were cheerful and helpful, and they worked with us to get an appointment time that would disrupt our workday as little as possible.  Technician Nathan was perfectly on time.  He was friendly and professional, everything you would want in a technician (he was even very kind to my pet).  He explained up front what the maintenance service would include.  Fortunately, no problems were encountered.  One component was at the end of its useful life, and he gave me the option of replacing it now or waiting, and he explained the ramifications.  I played it safe and replaced the part while he was here.  When done, he explained the company's optional service contracts with absolutely no pressure to buy anything.  I did decide to purchase a one-year agreement just to avoid the hassle of trying to remember to schedule next year's maintenance appointment.  It's a good idea to have reliable service providers lined up for your plumbing, electrical, and HVAC needs in advance, and I feel very confident in Pacific Air Systems after this.

"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"We have a very old, complex HVAC system and they have been very responsive and keep it running smoothly. I will continue to use this company exclusivey."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Estimates were detailed, clear & there were no extra charges on the day of service. Timely arrival and completed work prior to expected finish time. All work was reviewed with us to ensure there were no concerns before leaving. I would absolutely use Post Results again for my HVAC needs."

We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!\n

"Best customer service and went above/beyond to help us find a problem with our HVAC system. They were professional and extremely great at communicating the process. I will use their services again !!"
