How Old Must My System Be Before Replacement Saves Me Money?

If you have a system that’s only 5 years old or less, the savings probably won’t offset the cost of installation. An older HVAC system, although running well, may be less efficient, to the point you’ll save money with a newer, more energy-efficient system. Ratings like SEER ratings on air conditioners, AFUE on furnaces, HSPF on combined heat pump devices, and general operation costs from year to year can help you make a decision. An Eanes professional can help you determine whether a new system will save enough money to offset the cost of replacement.

What Will I Need for Effective Commercial Air Cleaning?

There are a lot of commercial air cleaning and purification devices available on the market. Designed as add-on components, most of these air cleaners and purifiers will integrate directly into your air handler, immediately impacting the air flowing in to your building. Very important to certain industries in the Piedmont Triad of North Carolina, humidification and dehumidification options can both be important upgrades to consider. Another thing to consider is prospective energy loss from ventilation and dust collection systems. If you have an extensive ventilation system in place, there is always a risk that you will lose energy when the fans run. A management system will help keep this from happening, or you can upgrade to a system that uses only a limited amount of energy to ventilate exhaust.
