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.

My A/C wasn't blowing cool air. Tom was as dependable as ever, got it fixed immediately, and with his usual warmth and smile. I couldn't recommend him more highly!

He thoroughly inspected it, tweaked a few things and said we were good to g, no need to replace i. Good news. He was here for at least 30 minutes and left without charging us, said he was sure there was no charge. I think he could see by the destruction in our basement that we needed a break, and he did that for us. I highly recommend Tom's!

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.

He also took the time to discuss with me of something that needed to be done in the future regarding our unit. Omer was extremely trustworthy and honest! Also the price was extremely reasonable!!!

The Grenz folks came, carefully looked at the unit, and said, "If it were my furnace, I wouldn't do anything. It is running the way it's supposed to." This second opinion cost me something, naturally, but it also saved me between $5,500 and $19,500 (two quotes from the other two companies). Jim seems like a straight shooter.
