Air Ducts

You invest a lot of money in your heating, ventilation, and air conditioning (HVAC) system. If you want to get the best value out of your equipment, schedule our professionals to inspect your home’s air ducts.

Poorly maintained ductwork restricts your system’s airflow and forces your equipment to work overtime to disperse fresh air through your Wauwatosa, WI, home. Our indoor air quality (IAQ) specialists at Gross Heating & Air Conditioning will inspect and help you maintain your air ducts, keeping you healthy and comfortable.

Schedule an appointment today and be sure to ask about a free consultation.

“We moved to Wauwatosa about 4 years ago into an almost 100-year-old house with hot water radiator heat and AC unit in the attic that only cooled the 2nd floor – both systems very different from our previous house. We started by using the HVAC company the previous owners had used but we were not completely satisfied with some of the work they had done. Gross Heating & Air was recommended to us and we have been so pleased with their service!! Not only do they do a great job with seasonal maintenance, but last year we also had them put in a heat pump to replace the AC unit in the attic and Joe was able to figure out how to get AC down to the first floor (especially the kitchen which has made such a difference!). This year Joe helped us again with a plan for replacing and moving our hot water heat boiler and cleaning up a mess of hot water heat pipes in our basement to clear the way for some electrical work. Every technician who has been to our house has been extremely pleasant and professional! We apologize that we do not remember the names of the individuals who worked on the heat pump installation, but they were wonderful as were Randy who has been here a couple of times for maintenance and Mike K, James & Owen who just completed this boiler project in our basement. Thank you all so much – we are so very pleased with the results!!!”

- Laura K.

“I couldn’t be happier with the service and professionalism from start to finish.
1. Make the call and you will greeted by a very pleasant human
2. Schedule an appointment for a quote and you will be met with someone who is knowledgeable, helpful and not the least bit pushy. I felt like Joe wanted to make sure I got the exact right product for my home and my budget.
3. Schedule the installation and the people who come out will be on time and professional. Brad, Owen, and Kaden were a joy to have in my home. They were pleasant, efficient and did not leave a speck of dust inside or out.

We have been with the Gross company for years and will never go anywhere else!”

- Mary W.

“Brad, Daniel and Joey were all very pleasant and professional! They installed a new AC, furnace, and air purifier for us. During the installation, they found that the filter in our Aprilaire was dirty and needed to be replaced. Brad happened to have one in his truck and popped it in without us even asking! They actually seemed to like their work! They did a super job cleaning up after the installation was done! Excellent service!”

- Richard O.

“This review is for the entire team who assisted me, beginning with the office personnel who booked my appointment for the same day, to keeping me informed that Randy was on his way. That is a big plus in by book.

Randy was friendly, personable, clean but all business when got to the A/C unit. I appreciate the fact that he thanked me for my USAF service.

I requested his business card because the next time my daughter or I need any furnace or A/C work, he will be the one we call for !

“As usual, Randy was informative and personable. I assume since Randy’s been with Gross for a while, they’re aware what a valuable asset he is to their company”

- Scott D.

“Randy was professional and personal. Diagnosed cause of my furnace failure immediately and worked to fix it within an hour.
Spoke about replacement in honest terms but for now got me fixed so I am warm tonight!
Thank you Randy! I would be honored if you serviced my heating and air units.”

- Jane K.

“I am extremely pleased with the service on my furnace and humidifier that Harrison did today. He was very knowledgeable, polite and courteous. I appreciated him explaining everything to me. We have had Gross Heating for many years and have always been pleased with your service. And I would like to thank your receptionist who took my call for being so pleasant and helpful.

Karen J.”

- Karen J.

“Team from Gross installed a new boiler/water heater/thermostat with a high degree of efficiency and professionalism!! We wouldn’t trust any other company to upgrade our heating system. Ask for Jerry when you need service or quote on new system, over 30 years of experience!!”

- Shawn C.

“From the service person, Bill, to the salesman, Joe, to the installers, Colton & Harrison, we couldn’t have been more pleased! Everyone involved was prompt, honest, respectful, tidy & polite. When the Tosa inspector came he said, “They did a beautiful job!” We are enjoying our warm home on these cold days. Thank you!”
