Gross Heating & Air Conditioning

Gross Heating did an absolutely wonderful job installing two furnaces and air conditioning units at my home this past year. From start to finish they have been a delight to work with! If I could give them 10-starts I would… thank you Gross Heating for your quality work and fantastic staff. Cheers!

Jeff has about 40 years with the company. He knew what system was best suited for our home.
Jessie has over 20 years with the company. He and and the team did an outstanding job on the Boiler replacement. Our old system was 62 years old when it died. At the end of the install and during the initial system startup, we had a frozen pipe burst. It happens. Jessie made a call and extra vans showed up and repaired it within hours.
The people working for this company are great.

The team arrived on time and started working right away. Everyone was polite and professional. I was given a detailed how-to with both my new heating and air conditioning systems. They even turned off all lights and didn’t leave any mess behind which I really appreciate! Def recommend this company.

We are so pleased with our salesman, Jeff, who completed the primary installation design and followed up with us before and during the installation. He prepared us for what was going to happen. We were just so confident that what he told us was true and accurate. He presents as both experienced and knowledgeable.
The installation team spent nearly half a day reviewing the plan within the context of what they saw in our house then began installing. The team communicated well, usually telling us when they would leave or return. They were so neat and precise with their work. There was no mess left behind in any of the 5 rooms in which they installed the mini split units not outside where they ran the lines. Every step of the process they seemed to check and double check to make sure the work was done correctly. They even made several calls to Mitsubishi to ensure that they were correctly installing. The installation team worked well together.
In addition to the salesman and installation team we are very pleased with the Mitsubishi mini split system. It is working for us exactly as we had hoped and exactly how Jeff described it. My wife and I are totally satisfied customers and would confidently recommend Gross Heating and the Mitsubishi mini split system to anyone who asks!

THE. BEST.

There simply are not enough superlatives to convey the excellence that is Gross Heating.

My old furnace died Saturday night. Today, my new furnace was installed! From my very first distressed phone call placed after hours on Saturday night, to the very last moments with the installation techs today, my interaction with Gross Heating has been exceptional.

Michelle, Randy, Nels, Greg, Colton, Mike, Cody and MJ all performed their jobs with a level of customer service rarely seen anymore. While each of these persons played a different role, (all significant), each made sure the process was efficient and seamless. Their attention to detail and focus on customer satisfaction was their end goal every step of the way.

I had used Gross for years maintaining my previous HVAC system, so when I needed service I knew exactly who to call! I will continue to use Gross Heating for all regular maintenance on my new system! Thank you for your exceptional service, and commitment to excellence! I highly recommend Gross!!

Gross Heating has always sent qualified and responsive service techs to service my home system. They are thorough and willing to listen to my concerns doing more than just follow a check list and leave. Really no reason to call elsewhere for HVAC work.

Amazing! From the office staff, to the technicians, everyone was great! When I called in to let them know my furnace was not working they were very responsive, confirmed a date and time right away. Randy came out today and was on time, very professional, friendly and informative. I cannot recommend them enough!

Great experience. Jerry has a top notch staff. Prompt. Said they'd start at 7:30 a.m. and they were here and ready to work. Colton and James were polite and introduced themselves to us. Very neat. They put floor coverings over our carpet. They took all old equipment out and cleaned up. Jerry stopped by to check how installation was going and oversaw connection of thermostat to WiFi. Explained use of thermostat. Colton showed us how to change filters and explained maintenance. Very honest and reliable. Highly recommend.

I had an entire new gas furnace, AC and humidifier installed by Gross last week. I had used this company for my hvac maintenance for years so when it came time to purchase a new system I knew who I could trust. Brad, James and Bill arrived on time and actually finished early, I don’t think they even took a break. They were friendly and made sure I knew how everything worked before they left. Everything was installed professionally and cleaned up/ disposed of when the work was completed. I am very pleased. I highly recommend Gross!

Our family recently had our furnace replaced by Gross Heating & Air Conditioning. The process of replacing the furnace was like clockwork with every required task. The attention to detail was meticulous with a high quality of work including adjustments to items from when the house was originally built. We were very pleased with the entire process and would highly recommend Gross Heating & Air Conditioning to others.
