The concept of HVAC has been around for thousands of years. The ancient Romans and Greeks used channels under marble flooring to distribute heat. However, it was until 1902 that the modern A/C idea was launched by Willis Carrier. Today's systems have experienced tremendous technological upgrades that make them significantly different from the older ones. Let's explore the recent HVAC history that has contributed to that.

"Hartman Brothers has always provided excellent service. From installing a new AC/furnace system to their biannual maintenance visits - they are the best!"

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"Brian showed me what was wrong with my air conditioning unit and explained everything so I could understand. He spoke to Vicki at the office regarding a needed part that would have to be ordered. They could have slapped a generic part on, but it would have only been a short-term fix. Instead of taking the easy way out, they are getting the part made for my unit so it will stay fixed, and they are coming back to finish the job as soon as they have the part. Hartman Brothers is ethical, knowledgeable, friendly, and they do the job right! I highly recommend them!"

"Honest people and good service. Lime anything you don’t know how to do yourself, expect to pay the premium for someone that took the time to learn how:)."
