How Healthy is the Air In Your Home?
Lemanski Heating & Air Conditioning offers indoor air quality testing using Air Advice monitors. We can test the quality of your home's air by simply setting up our monitor in your home for 5 days. The monitor will test for particle allergens, chemical pollutants, carbon dioxide, temperature, relative humidity, and carbon monoxide. We will provide a detailed report of your home's indoor air quality and will go over your options to correct the quality of your home's indoor air.
Energy Efficiency
Energy Efficiency is not just a buzz phrase, but a practical way to conserve energy and save money. Reduce your eco footprint and your energy bills at the same time with energy efficient heating and cooling units. Although the efficiency of your cooling and heating equipment will have the greatest impact on your energy usage, other factors will also help reduce energy costs.
