"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!!!"

"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.

"Purchased 2 smart thermostats, installed them myself and apparently blew a panel board I didn't know I had. They moved the new panel out where I could actually see it, previous tenant had hidden it behind the furnace, and repaired all of the damage I had unwittingly caused. Explained everything, kept me up to date while they were doing the repairs, and overall, I just feel very glad I went with Rob and HVAC Service Pros. The previous company I'd used, Ranger HVAC, had told me things in my system were A-OK, when they weren't. I highly recommend hiring Rob and HVAC Service Pros. Quick response, knowledgable, saved my bacon. No complaints, nothing but praise."

"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."

"Bradley knows what heâ  s doing. I originally hired Seatown Electric to come out and install an in-house backup generator. Bradley came out to install the generator and found that we had some pretty dangerous wiring at the panel and it was not nearly up to code. I was in the HVAC industry 30 years ago and the mechanical theory in which Bradley explained made complete sense. Bradley finished up the generator install and he gave me a bid to fix the issue. The same day, we called Seatown and we made an appointment for him to come back and do the work. Bradley and Austin showed up at 7:50am, 10 minutes before the job started. They met with me and got started. I always like to look at service techs trucks to see what kind of person is working on my home. Bradleyâ  s truck was immaculate. Extremely organized, very clean and it looked like a service truck that was on the DeWalt showroom floor. The instant I saw Bradleyâ  s truck, I knew his work was going to be perfect. The professionalism from both Bradley and Austin was outstanding. They worked extremely hard for almost 11 hours that day. They didnâ  t mess around, they had their mind set on the job and I was extremely impressed at their work ethic. We have been through 4 major renovations between our two homes and have used a myriad of different contractors, but never have we had a team close to as good as these guys. I would put every apprentice with Bradley, he knows what he is doing. Seatown is lucky to have this guy, they better take care of him. Great job guys!"

"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."

"Prompt, clean quiet, professional, good price. Pretty much what you would expect for your money. Heat pump and air handler and some ductwork changes. I'd recommend them."

"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."

"They were very detailed. Identified a critical HVAC defect that we weren’t aware of."
