In response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out. Lennox has led the way in the manufacture of cooling systems that use chlorine-free R-410A refrigerant. Because R-410A contains no chlorine, it is considered ozone-friendly.Cooling systems are designed to use R-410A refrigerant, therefore providing an economic benefit in addition to the environmental benefit. R-410A systems are also known for improved reliability, quieter operation.

During extremely cold weather, your home loses moisture to the outdoors, and the humidity level may drop to as low as 10 percent. A humidifier adds moisture to your indoor air and can help relieve ailments related to dry respiratory membranes.

At DaveTech & Serv,LLC, we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits.

The amount of sound generated by a heating or cooling system can have a significant impact on comfort. Inside the home, a low sound level means no sudden blast of air at startup and smooth, vibration-free operation. Outside the home, low sound levels help you keep the peace with your neighbors. This is particularly important, given that many communities have noise ordinances.
