David’s heating and cooling is the BEST! I have been a customer for 25 years. I have lived in 3 locations and they are the only ones I trust to address heating and cooling issues. In each location they have been polite, willing to answer questions, and they left my home even cleaner than it was!!!! They have installed a boiler heating system, and 2 heating & cooling systems for me. In all 3 cases they replaced very old systems. Many of my neighbors have used them as well. There have been no complaints. And their prices were competitive, often thousands of dollars less! The estimate included great name brands. They also will maintain your systems with yearly maintenance checks.
Worked with David Heating & Cooling this past year after forgetting to get annual service work done on my boiler the past 2 years. They came out and took care of business at an extremely reasonable price and also caught a leak in my Expansion Tank that was on the verge on bursting and costing me significant dollars. Everyone I dealt with was extremely helpful at the front desk to the technician that came out. Highly recommend
David Heating & Cooling was great! As a new homeowner they were very helpful and answered all of our questions. During our maintenance check they found a few issues with the system and were able to fix them on site! One piece they needed to order and came back the next day to repair. Very pleased and will always be using in the future!
Modern Temp is great! Knowledgeable, and reasonably priced. They do their best to get to you on short notice for emergency situations. Totally recommend them!
Ryan and Tim did a great job installing a new furnace for us. Went above and beyond! Prompt, professional, knowledgeable. I highly recommend them!
Loved working with Tim. When I first called on a Thursday, with a non-functional ductless AC, we scheduled an appointment for the next week. Turned out that he made the effort to come by the next day to help out. Old AC was dead and we made another appt to install a new heating/cooling unit which was complete just in time for the impending heat wave. Through the entire process, Tim was very professional and responsive, and did and a great job explaining what was going on to someone who knows nothing about Air Conditioners (i.e. Me!). Very pleased and would not hesitate to recommend!
