"After our old HVAC system failed during a heat wave last summer, we thought we'd be without air conditioning for weeks. ParkerCoolFix had us up and running within 24 hours! They even worked late into the evening to get our family comfortable again. The new system is incredibly quiet and our energy bills have dropped by 30%. We've already recommended them to three neighbors."

"Our elderly parents live with us, and when their bedroom became too hot during the winter, we were worried about their health. ParkerCoolFix installed a new heating system with zone control, so their room stays perfectly warm while the rest of the house is more energy efficient. The technicians were so careful and respectful of our home. Great work!"
