Sizing Considerations for Buying an Air ConditionerAir conditioner sizing is a critically-important consideration when you're planning to purchase new cooling equipment. According to the U.S. Department of Energy (DOE), an A/C's size needs to match the space it's going to cool. An undersized A/C will run for extended periods, use a lot of energy, but won't cool your home's interior sufficiently for comfort. An oversized air conditioner will only run for short cycles, so it won't dehumidify effectively or cool your living space efficiently.

"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!"

"The staff is wonderful and the technicians are "top notch" at Hartman Brothers! I have used this company for the past 25+ years for all my regular maintenance checkups and repairs. I have never been disappointed with the quality of work by the Hartman Brothers service technicians. My most recent service tech was "Josh." Josh was very courteous and professional. I will continue to use Hartman Brothers for all my HVAC needs for years to come!"

"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers."
