“Scheduled a furnace check up for 11-16-23. Hasn't been done in a few years since an inducer fan upgrade the Trane dealer in Menominee, MI did. Suspected something wasn't right since the upgrade, but it seemed to run o.k. Randy showed up on time and gave it a good cleaning. He also did some testing to address my concerns about the 2nd stage firing. He verified that it wasn't correct and tried to resolve the issue. Being that this was only a cleaning and check-up he was under some time constraints. Told me what he found and I agreed it has been like this for awhile and we would address it at a different time. Based on what he told me, I took it upon myself to check the wiring like he suspected. It turns out the 2 wires for the pressure switches were reversed since the upgrade that the Trane dealer did. I switched them and it is running like a swiss watch now. Both stages fire like they are supposed to. Thank you Randy for sharing your findings on this issue. Also have a gas fireplace insert on order through GPS. Jerry was very helpful in picking out what we wanted and price was what we expected. New furnace and air will be in the not so distant future and we will put GPS at the top of our list when the time comes. Thanks.“
“Very knowledgeable, courteous, and showed up on time. We had our furnace and gas fireplace cleaned. Then at a later date we had our furnace replaced and switched from propane to gas. They took care of our appliances being converted also. Great company.Services: Heating system installation“
