How important is adding humidity to my home?

​In the winter, air is drier. This dry air can damage the woodwork and furniture you have in your home as well as zap the moisture from  your skin. Dry air even makes you feel cooler because your body senses heat as a combination of temperature and humidity. Adding humidity to offset this drying process will improve your comfort as well as preserve the woodwork in your home. As an added benefit you may actually be able to lower your thermostat a couple of degrees. You will not only feel warmer, but will actually lower your heating bill!

How often should I change the standard throw-away 1" filter?

You should change the standard 1" filter every 30-60 days. Believe it or not, a filter actually becomes more efficient as it gets dirtier - up to a point.  After peak efficiency is reached, the efficiency drops again. Make sure to inspect the filter and use your own judgment. Don't let the filter get "clogged" as this can cut down on the efficiency and/or cause damage to the unit.​

How long can I expect a new system to last?

If you have a qualified technician perform regular preventive maintenance and service suggested for your unit, industry averages suggest that a heat pump system should last 10-15 years and a gas furnace with AC should last as many as 15-20 years.​
