Our indoor air quality products will help you maintain a clean and healthy indoor air environment, creating a safe haven for your family.
Your home comfort system is most likely the single biggest use of energy in your home. In fact, over a third of the energy used in the United States is used to heat and cool buildings. Having a properly designed and installed heating and air conditioning system will have the biggest impact on your energy costs.
As licensed contractors and specialists in the field of heating and air-conditioning, we have the tools, the equipment, and the experience to keep your equipment running smoothly all year long. If it is emergency service that you need, we are available to assist you, 24 hours a day, 7 days a week. To help reduce those service emergencies, we offer preventative maintenance to keep your comfort system running at peak performance.
Extended warranties allow customers another opportunity to manage their ongoing costs of operations. Since your heating and air conditioning system is used 24 hours a day, year round, it requires service as it operates. Extended warranties can cover the bill for all costs, including labor, during the insured period.
With today's tightly sealed, well insulated homes, the air inside your home can be 2-5 times more polluted than the air outside. Air Filtration Products - Remove contaminants such as pollen, mold and pet dander that aggravate allergies. Humidifiers - Properly control humidity for personal comfort, to protect furniture and wood floors, and reduce static electricity that damages electronics.

I found out the hard way about Fondy heating and air's unfair, unprofessional business practices. Take caution do yourself a favor and call one of the 20 plus other heating and air conditioning services in Fond du Lac county. After being over charged and try to resolve this billing mistake with an very unprofessional lady by the name tammy I requested to speak with the owner Mr. David Larson I just kept getting Mr. Larson is not in. tammy made it clear that Mr. Larson was never going to be available or return my calls. At this point I had to get my attorney involved. Just not worth the headaches

RUN!!!! I would give zero stars if I could.
Absolute worst customer service from “Tammy” when I called to have my AC looked into. Made me feel as if I was inconveniencing her by calling on a Friday afternoon.
Technician Nate came Tuesday and said our AC condenser hose was plugged which pooled into our furnace and filter compartment. Nate then stated that it happens all the time and wanted to look at unit outside. Less than 3 minutes later, Technician Nate was seen leaving my property.
With many questions, I called Fondy Heating for answers as to what the diagnosis was as water was still

I have never written an online review before but after the horrible service I received from Fondy Heating & Air it was required. Had them come do a furnace clean & check in which I had no issues on the furnace. After the guy came out a day later we noticed water leaking out of the furnace. When I called to have them come back to check, the lady on the phone was rude saying “is it that bad because we are busy”. The guy came out a few days later and noticed the trap hose cracked and said “sorry it could have happened when I put the hose back on from the cleaning”. He ordered new hose and

This company was great to begin with!
They took all info on the phone and gave me an estimate via phone--didn't even need to send anyone out to the house.
Service guys we're on time, thorough, and just great overall! The new furnace is sooo much better than the old, and it was $2000.00 cheaper than the local competitor! --for the same kind...
Would recommend this company any day!!

Was not on time and did not call to notify me of the delay. Instead I found out when I called the company to find out what happened to the agent who was scheduled to come to my house. Will be looking for another company to service our heating and air conditioning due to the lack of communication and punctuality.
