Warehouse on wheels for One-Stop service
Our warehouse on wheels carries a full line of inventory including all parts to complete your job. This means no waiting for parts, just the prompt service and repair you deserve.
Superheat and Subcooling A refrigerant undercharge of only 10% can increase operating costs by almost 20%. Which is why Comfort Zone uses state of the art gauges, delivering the most accurate charge available. We first determine a temperate drop across your cooling coil, then deliverer a 100% accurate charge utilizing superheat and subcooling temperatures.
Leak Detection Refrigerant should never need to be replaced. If it must be added every year, there is an expensive leak that should be repaired. Comfort Zone has state of art leak detection equipment. Combining sensitive sensor technology and ultra violet leak detection dye, we are able to find and repair undetectable leaks.
THE RED CARPET TREATMENT MEANS NO CLEAN-UP FOR YOU
Our Service Technicians are dedicated to leaving your home just the way they found it. So, before beginning any plumbing or repair job, they spread the red carpet to protect the work sight. Special consideration for our customers – just one of the things that make Comfort Zone unique.
