Q: How often should I change the filters in my HVAC system?

A: We recommend checking the filter monthly; if it looks dirty, change it. Filters should be changed a minimum of once every three months.

Q: How often do I need to change my batteries in my thermostat?

A: We recommend that atleast once a year you change them out. An idea is change them when you are changing your smoke detector batteries.

Q: What is Indoor Air Quality?

A: According to the Environmental Protection Agency (EPA), your exposure to air pollutants can be up to 100 times higher indoors than outdoors. York indoor air quality products handle pollutants, humidity and other issues to improve your health. 


Get the Right Size to Save the Most Money

  •  In most homes, the heating and cooling system is too big.
  •  Besides wasting energy, improper size can create uneven temperatures, poor humidity control and maintenance problems  over time.
  •  Improper installation can reduce system efficiency by up to 30%.
  •  But properly sized ENERGY STAR® qualified equipment can easily cut your annual energy bill by hundreds of dollars. 

The Seasonal Energy Efficiency Ratio (SEER) rating measures the efficiency of central air conditioners or heat pump usage over a theoretical cooling season.

It's a simple ratio of the amount of cooling provided by the air conditioner — as measured in BTUs — with the amount of energy the central system consumes — measured in watts/hr. So if you see a system rated at 16 SEER, that actually means it produces 16 BTUs per watt-hour.

The Heating Seasonal Performance Factor (HSPF) measures a heat pump’s energy efficiency over one heating season combined with its SEER value over one cooling season. The HSPF formula is slightly more complicated. But the HSPF rating uses BTU to calculate useful heating output (including electric heat) divided by the total electricity energy heat pump consumed (in watt/hr) during the heating season. 

The Annual Fuel Utilization Efficiency (AFUE) measures average efficiency for furnaces, boilers and water heaters. This is a measure for a theoretical heating season, not including electricity.

For SEER, HSPF and AFUE, higher numbers indicate higher energy efficiency. These numbers are then used in two energy rating programs: 

EnergyGuide label:

Manufacturers of heating and cooling equipment are required to display the EnergyGuide label. This label estimates how much energy the equipment uses, compares energy use of similar products, and gives approximate annual operating costs. Your exact costs will depend on local utility rates and the type and source of your energy.


ENERGY STAR® certification: ENERGY STAR® is a voluntary energy awareness program developed by the U.S. Department of Energy and the Environmental Protection Agency (EPA). Our high-efficiency systems are labeled ENERGY STAR to identify products that are at least 15% more efficient than standard products.
