Since 1959, West Allis Heating, Cooling, Plumbing, and Electrical has combined old-fashioned values with the highest quality service, products, sales, and support—all at competitive prices.We offer services that many HVAC contractors no longer do as they require extensive experience and training. For example, we create custom ductwork at our in-house metal shop which ensures proper unit sizing for consistent air flow. Our ductwork not only operates efficiently, it looks great so it doesn't need to be covered or hidden.Our highly-skilled technicians install and provide maintenance for oil furnaces and boilers—a rare commodity these days. We can also provide oil to gas furnace conversions, which typically offer greater efficiency and less hassle.West Allis Heating also repairs sleeve and window air conditioning units—no one does that anymore. We also sell new window units through our WAH Comfort Store.
