We highly recommend Dahlquist Heating and Cooling. They quoted a fair price for our new residential construction project which included a boiler system, mini\-split a/c, on demand hot water and ventilation. The office staff was always able to answer our questions and make suggestions. The installers were polite, efficient and knowledgeable. Bring a new construction, we needed several installation appointments over the course of about five months. They always made sure to get to us promptly. We made the right choice when we chose Dahlquist Heating \& Cooling.
