Gas furnaces come in a variety of sizes, brands, efficiency ratings, and comfort profiles. Different Furnace types will be used based on customer preference, budget, and the home itself. At Marr’s Heating and Air Conditioning we sell Carrier and American Standard gas furnaces. These 2 brands have seen an exceptional score of reliability from sources like consumer reports. Our service technicians also play a huge role in determining what we sell to our customers. We are happy to say that on top of exceptional build quality, warranty and factory support, these brands also get an A+ rating from our installers and technicians!
