What is A/C Tonnage?The relationship between a system’s A/C tonnage and the size and characteristics of the home it’s in makes a difference in its performance. Each ton of an air conditioner can remove 12,000 Btus of heat from your home in one hour. When you’re selecting a new cooling system, whether it’s central or portable, finding the right size is crucial for your comfort, energy costs and the lifespan of the equipment.

"The service was great as always. The 2 men who came to install my new furnace were very professional and took the time to explain what they were doing and showed me what the problem was with my old furnace. Thanks Mr Hartman for coming up North and for having a great crew."

"22 years ago Hartman's installed our furnace/AC. When the unit recently started having serious issues Hartman's tried to repair the unit, spending a few hours but the aging unit had given all it could and wouldn't stay fired after the flame sense was cleaned and the rest of the unit examined. That tech, who's name I have unfortunately lost - possibly Jim, thoroughly explained everything during his inspection so I could relay the information to my husband. After I discussed financing options with Hartman's for the replacement Rick Hartman cared for every detail and made the transition seamless. Our issue began on 3/10 and the replacement unit was installed on 3/14; a needed part was driven overnight to meet the installation date. Kevin and Jason from the install crew were very knowledgeable, professional and quickly fabricated a 3 in metal base for a perfect fit. This crew comes prepared! Josh set the unit air force specs 4 times until we found my personal preference. Roger Hartman came out during installation to give us our paperwork and check with the install crew. The installation was completed in 7 hrs and the crew never took a break! I would hire Hartman's any day for a red carpet customer service satisfaction experience with a company that has a great reputation, a friendly and professional crew with many years of accumulated experience, all the employees clearly work well together and have excellent knowledge and workmanship and work ethics. I highly recommend Hartman's, you won't be disappointed. They not only arrived on time but we're actually a little early! "
