I worked at Four Suns for a little over a year. I was a technicians assistant. It is a great family business that focuses on looking out for the customers. It is a smaller company but they really care about their employees, like family but everyone their enjoys working hard. If you are looking for anything heating and air related then this is the company to go too. They want to make it affordable and do great work! They have very talented techs that are great at explaining if you have questions.

Leipart heating and cooling is a great company. They have cleaned our vents, installed a new ac unit, and fixed our water heater with no problems. I have known the owner for a few years and consider them very trustworthy. If you have any HVAC needs, I would recommend Leipart Heating and cooling everyday and any day problems arise.

We were exceptionally pleased with the service that we received from this company and from Ralph. Ralph returned all her phone calls in a timely manner and was able to come to our house on a short notice to take a look at our heater. Ralph was very thorough and explained all the issues with our furnace, he offered some solutions and his recommendations. He was extremely polite and is definitely going the extra mile to help us get our heat back on. We would definitely recommend.
