"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

"Chris and his co-worker were very good. My hot water heater was in a very tight space. With that being said they did a nice job on the sodering. Chris replaced a valve he didn’t like. They did a great job cleaning up. Once installed and powered up they waited outside for 30 minutes to make sure the water got hot."
