Most people have heard of ductless cooling and heating systems, and they have probably seen the small, indoor devices installed high on walls in homes, restaurants or office buildings. But what do you really know about these systems? Whereas traditional heat pumps and central air conditioning systems force cooled and heated air through ducts, ductless systems deliver air directly into different zones.

The luxury of a tankless hot water heater: Nearly limitless hot water. If you like to take LONG BATHS & SHOWERS without worrying about losing hot water, this is your first-class choice. The lifespan of a tankless water heater can be more than 20 years. That is double the lifespan of a standard water heater. You'd have to buy two standard water heaters in the time to own one tankless water heater. Pair that with lower operating and energy costs, tankless water heaters are a smart investment that everyone can afford, not just the rich and famous.
