Client Reviews

In May of this year, my wife & I had decided to replace our aging furnace and air conditioner. After doing some research and interviewing 3 different heating and cooling companies, we decided on Mazza Heating and Air Conditioning. Their line of efficient and innovative Lennox products plus the competitive price were the deciding factors. Kevin Toews and his team performed a very clean and professional installation in just a day and one half. The new M30 programmable thermostat is simple to use and very advanced. We are very happy with our decision and choice. The improvement in our air conditioning is very noticeable and we can't wait to see the savings in efficiency when fall arrives and the upcoming heating season.

Thanks to Kevin and the Mazza team.
