I called Pioneer Plumbing about my heating problem, as their office is just up the street from me and I wanted to support a local company during Covid. The heat would not come on on all 3 floors of my small house and had not been working properly for several months. Unfortunately the "day of", my appointment time got changed and my daughter handled the first 30 minutes of the appointment until I got home. The upshot was we were told that all 3 valves were not working, that parts were not available and that our only option was to replace them with Honeywell valves, for which they would give me a quote (It was looking like it would cost several thousand dollars).
A few days later, I managed to locate the original installer of the heating system. He cleaned them and flushed them and fully serviced my furnace
and charged me just over $600 for his 1 1/2 hours of work. He said should the valves need replacing down the road, and he did not anticipate anytime soon, he could do the job for @ $1000, but it was not necessary at this time. The heat has been working fine ever since. I expressed my dissatisfaction to Pioneer through several emails that were acknowledged but not followed up on. I finally got a text to leave my Positive Feedback on google. I expressed my negative feedback. I got a call New Years eve day that I could not respond to as I was at work. I followed up yesterday, still no response. The communication is not the best.
Update: While initially I was dissatisfied with this company, they addressed and resolved all of my concerns to my satisfaction, and issued a full refund.
