It's mid-December and the temperature is dropping to zero tonight, so of course our radiant heat…read moreboiler pump started making a horrible noise. I called Gross Heating on Monday to have someone come out asap. I was told Wednesday morning was the soonest they could make it. I was reluctant to call another company because in the past I had a bad experience with another. The last time Gross came out, they did a great job, so I called them back and said okay to Wednesday. They said they could actually send someone out Tuesday, late in the afternoon. The technician came out and apologized, saying this job may take more time than we have today and run into a lot of overtime. So, a new appointment was set up with another tech for Wednesday morning. In a way I'm glad this happened because the new tech was excellent in every way. He had the part I needed on his truck and had everything completed at noon. While he was there, our daughter called saying you won't believe this, but my boiler stopped working and I have no heat. Gross had anticipated the tech would be at my house the entire day. I asked if we could go over to her house to take a look at her boiler. Gross said okay, so off we went. She needed a new pump motor, which luckily he also had on his truck. In conclusion, both of our heating systems were fixed in the same day and at what I feel was a reasonable price. I trust Gross Heating and wouldn't use anyone else.

The owner, Randy responded to my emergency call where we determined I didn't need an immediate service call. The next morning Mike , the technician, repaired the damage and even tried to determine the squirrels entrance point. Competent, professional and polite- like all Gross employees- Mike determined it had to be the chimney. I don't know why anyone would call any other company! Thank you Randy and Mike.

The person they sent was nice and helpful but stated that he wasn't the HVAC guy; that's a different guy. Don't have any idea why they didn't send the HVAC guy since it was clearly requested that HVAC work was needed. He couldn't actually address the main need on the water heater (which is fine...it wasn't them that installed it), so I had him skip the drain pan and just do the p-trap which went fine. I emailed back out to get the HVAC guy - no response. So they ghosted. Because of (A) not sending the right people upfront and (B) not responding after the fact, there's no way I can justify more than three stars.
