My thermostat died during a heat wave. Randy and Hunter came and replaced it the morning after I called Gross. Randy was very professional and personable. He took the time to explain, in detail, what was going on and what my options were. I will call Gross for any of my future HVAC needs. read more

It's mid-December and the temperature is dropping to zero tonight, so of course our radiant heat boiler 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. read more

Gross Heating & Air Conditioning - Technician working on our boiler. Excellent experience. - Heating & Air Conditioning/HVAC Near Me - Brookfield, Wisconsin

Once again, Gross Heating to the rescue! While they didn't remove the squirrel from my furnace, they dealt promptly with the aftermath. 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. BTW, the squirrel lived!! read more

We have had Gross service our Bryant high end (96%) furnace and our central home a/c unit(s). Especially after another area competitor had failed us. Anyway, we had finally decided to "pull the plug", and let them replace and install our whole home humidifier with an Aprilaire 600M model. Jerry (an owner) convinced me that this was the right one for our home. I believe he's correct, too. Fewer moving parts and more reliability. Plus it's much easier to maintain. Most importantly, it introduces particularly the proper winter humidity we need. Recommend Gross for a competent job. Pricing seems in line with this market. read more

I took the day off for my appointment. My appointment window was 12-3. They did not show up or call.

I simply cannot say enough about this company. We have been customers for years and they have provided us with friendly, timely, professional service every single time. The technicians couldn't be nicer and more knowledgeable. From the initial phone calls to the final job, it has been a pleasure. They have kept us warm and cool for many, many years. I very highly recommend this company. Thank you Gross! Dawn D. read more

I have had Gross Heating taking care of my furnace and air conditioning needs for the past 20 years and I cannot say enough about their professionalism, knowledge and efficiency. From the receptionist to the techs that come out to do the work they are friendly, engaged and know what they are doing! I highly recommend them, you will not be disappointed in the least! read more

I am a first time home-buyer as of March 2017 and ran into an issue with my A/C in my condo. I wasn't sure who to call or what to do as I had been a long time renter in the past. A friend mentioned they used Gross, so I looked them up on yelp and saw positive reviews, then called. Within the 2nd ring, a real person picked up the phone. She was kind and courteous, listening to the issue I was running into. She then transferred me to one of their technicians to see if he was able to walk me through the issue first (no charge!). He asked great questions and explained things well. He mentioned why a technician would need to come out. I then inquired about the cost and he explained how their pricing worked so that I wouldn't be surprised. I was transferred back to the woman at the desk and she got me an appointment same day. The tech was at my home in less than 2 hours. The tech's name was Doug, he was polite and kind. He was not judgmental and just listened to the issues I was having and started digging around right away. He didn't waste any time, which I appreciated since I knew I was being charged by the hour. Not only was he able to remedy the issue, he left me with piece of mind that it was now in better shape in case anyone else would need to look at the system in the future. Doug wrote me up a bill and charged my credit card right there. Simple and easy, I would use Gross again without hesitation. read more

Great service. Very professional and courteous. The new system they installed is perfect. Everything went very well. Happy and satisfied. Would recommend to everyone. Work was done in a very timely fashion. Have nothing but praise for the workmanship and quality. . read more

I could not have been more impressed with Gross's service. From the people I talked to on the phone to the service technician who came out to look at our furnace, everyone was so kind and polite, they all truly went the extra mile to make sure my home and my family were taken care of. Highly recommend. read more

A company that somewhere forgot that customer service doesn't always make you a buck. Hired Gross to provide a "custom" HVAC vent cover for our home. THEY did all the measurements, etc. Had an appointment with the owner to come out since it was such an unusual custom job after the initial visit by one of their techs. He ended up cancelling as he "trusted the initial tech's measurements". Cover took twice as long as promised to be made/delivered (8-9 weeks). I took it home to pop it in, and discover it's the wrong size! Call Gross and explain, they say a tech can be out the next day. He had to cut drywall, etc. but installs the cover. Much to our surprise we get a BILL for the tech's time ($128.83)! I call their office to explain the entire story to some kid who answered. I'm told the owner will call me back. No call. If YOU don't want to have to pay for THEIR mistakes, I'd look for another HVAC company. read more

Mike came out for an ac fan that stopped working. He diagnosed the problem almost immediately then gave me a bunch of preventative maintenance tips. Highly recommended read more

Excellent customer service! 2 kids home sick and no heat is no good. The dispatcher was very friendly and considerate, squeezed me into the schedule, and the service tech, Mike was very friendly and knowledgable. Had our furnace up and running in no time. Very reasonable, I appreciate not being ripped off. Will definitely call them again when needed. read more

I am currently working with Gross on a boiler project at our rental property. I have to say that I am thrilled at how timely and friendly everyone has been. When dealing with repair companies and contractors my expectations have been set very low. People are constantly late or no shows. Not the case with Gross. They are on time, friendly, and happy to explain things I don't understand. I am looking forward to having them do my repairs and upgrades. read more

Very unprofessional company, it's been over 6 times of them trying to fix the central air unit and they still haven't gotten it right! The owner is very unprofessional, and rude!! Save yourself time and the headache. Don't do business with this company!! read more

Gross. They grossly over charge. They grossly find any little thing to raise your price with. They grossly stare at your wife in the pool. Yes gross is very descriptive read more

We had a problem with our hot water heat, as the baseboard radiant heat in 1/3 of our house was not working. Their rep came out to "fix" the problem. I understood there would be a trip charge. He came out and spent an hour "looking" at the boiler and "looking" at the baseboards. He did nothing and said we should probably consider replacing the boiler as it was about 26 years old. The "repair" would cost between $800 and $1000 and then it could still have things go wrong. He charged us $130 for that diagnosis said he could come back and fix it after ordering a pressure gauge, etc. but he would have someone call about new boiler pricing. No one ever called until a week later I called them again. I also called Tom's Heating in Waukesha for a 2nd opinion. They came out next day and fixed the heat in under 1 hour for $169. The system was apparently 12 lbs low on air pressure and he added that and then bled the radiant baseboards. It has worked fine ever since. I would NOT recommend Gross Heating in Brookfield. read more

After being in my house just a year, I called Gross Heating for an annual maintenance on my "older" furnace. Turns out the furnace is 30 yrs old, not the 20 that I thought. The service technician did give me a warning that parts are no longer available, but did not try to talk me into anything unnecessary. He cleaned & did the normal maintenance and answered a lot of questions, giving me suggestions about what to expect. He was knowledgeable,friendly & efficient....I will definitely call Gross when the time comes for a replacement. read more

Last year we called Gross to come and look at our furnace - half our house was always cool in the winter and hot in the summer. The owner himself came out and advised us that our furnace was 10 years old and 80% efficient and that we did NOT need a new furnace. The problem was that our air ducts probably needed some dampers to balance out the air flow through the house. The duct work was encased in paneling so the cost would be about $200.00 for the fix. He gave us a shopping list of fixing the damper, getting a new 94% efficient furnace and a price for replacing our 34 year old central AC unit which we knew was running on borrowed time. He said nothing was urgent to replace since everything worked but he wanted us to have the info. Out of laziness, we didn't do anything. Flash forward to the present day and the next thing we knew its summer and our air conditioner was giving us problems. So since it was 34 years old we decided that it was time to replace the old gal and called Gross again. We were told that if we replace both the AC and go with a 94% efficient furnace that a generous rebate was available from the manufacturer. After talking it through and running the numbers we decided to pull the trigger on both the AC & furnace. They requoted the project (since 8 months had passed) and the quote came in $150.00 LOWER since there was a price drop on the furnace (I think Carrier was clearing them out for new models). A week later a team of 3 workers from Gross came out. It turns out our duct work did indeed have the proper dampers and the one leading to one side of the house were completely closed, so no need for new dampers - more savings! The crew worked like crazy and installed a new AC unit and the new 94% efficient furnace. They used the old concrete pad the previous AC sat on so we didn't have to pay for that - NICE! When the work was done they explained how everything worked and how to operate the new thermostat and understand its operation. Our house is much more even with the temperature feel and the new system is working great. I like the 'set it and forget it' type of thermostat and the new AC unit is VERY quiet. You can literally be standing next to it and you just hear the fan blades turn - it's that quiet. The fan on the furnace goes down to a low mode once the proper temperature is met and the temp in the house is comfortable and feels even throughout the whole house. A new furnace and AC is a costly project and let's face it, it's not as sexy as a new kitchen but you can't live without it. I'm glad we pulled the trigger on this and had both the AC and the furnace installed and I'm glad we called Gross to act as our contractor. The crew is great. They explained all our options, answered all our questions with no pressure and saved us money where possible. Once we decided to move forward they quickly came out, did a fast & clean install and picked up after themselves. This is how business should be done and I'm glad we chose them. read more

I was very impressed with all aspects of this company from the courteous woman who answered my initial call and her ability to set up an appointment on very short notice to the technician who came out and did a full cleaning and tune-up and identified the source of the loud noise the furnace made when it started. The housing to the motor was cracked and he found a new motor , went and got it and installed it same day for a reasonable price. If not for this we would have been without heat in the near future! Thank you Gross Heating!! read more
