Heating & AC Add-ons

Programmable Thermostat | Whole-House Air Filtration

Enhanced Indoor Comfort 

Whether as add-ons to a new or existing system, we offer several options for greater comfort and increased energy savings.

These include:

  • Whole-house Comfort Control.  If you’re heating or cooling your house with one thermostat or fewer than you need, your energy bills are too high. We can show you the added value and savings you’ll enjoy with multiple zones for  greater temperature control and energy efficiency.
  • Arzel Zoning Systems. Messmer recommends and installs Arzel Zoning systems in homes and commercial buildings throughout Southern Indiana.  Arzel Zoning Systems help you eliminate hot or cold spots, increase energy efficiency, reduce maintenance and equipment costs, and increase your return on investment.
  • Programmable thermostats.  If you leave the heat or AC on all day just so you’re perfectly comfortable when you come in, you’re wasting tons of energy and piling up the wear and tear on your home comfort systems. One or more programmable thermostats can provide the right amount of comfort and added savings we know you want.

Whole-House Humidifier | Whole-House Dehumidifier

  • Whole-house humidity control.  As an air conditioning system ages, it loses its ability to remove excess humidity from your home.  That problem can be solved with a whole-house dehumidifier.  The opposite is true during the winter months.  Dry indoor heat demands added moisture for increased comfort and energy savings…exactly what you can expect from a whole-house humidifier.
  • Variable speed control heating and cooling systems conserve energy by cycling on and off less frequently.  Instead, they remain on and self-adjust to provide more warm or cool air, as needed.  Variable speed systems also are quieter than conventional models.
