Air Filtration Products
Air cleaners effectively remove bacteria, pollen, animal dander, and other pollutants as small as 0.01 microns. That's 18,000 times smaller than the head of a pin. The higher the minimum efficiency reporting value (MERV), the more efficiently the cleaner removes particles. We offer air cleaners that range from MERV 10 to MERV 15 to meet your needs. For those families that have severe allergies, we also offer whole-house high-efficiency particulate arresting (HEPA) filtration systems.

Humidifier Products
Humidifiers work in tandem with your heating system to deliver desired humidity levels throughout your home. Maintaining proper humidity levels in your home is essential to maintaining indoor comfort during the winter months. Moderate humidity levels make you feel warmer at lower temperatures, which means you can set your thermostat lower without sacrificing comfort.
Depending on the size of your home, we offer a variety of humidifiers to deliver the right amount of moisture into the air. The sizing of humidifiers is measured in gallons per day (GPD), and we offer models from 12 GPD to 18 GPD.

Ultraviolet Light Products
Ultraviolet light kills bacteria and mold growing on your indoor coil before they are circulated throughout your home. UV lamps are installed near your existing indoor coil and work diligently to rid your home of the bacteria, viruses, mold, and germs that impact your home's health. We install one or two lights per indoor coil, depending on the size of the coil.
Carbon Monoxide Detection
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas, which makes it extremely dangerous. CO detectors can protect your family from deadly carbon monoxide gas. Fuel-burning appliances, such as oil and gas furnaces, gas water heaters, gas ranges and ovens, gas dryers, gas or kerosene space heaters, fireplaces, and wood stoves, are all sources of carbon monoxide.
A monitored carbon monoxide detector will alert you if high levels of this deadly gas are detected. Local building ordinances require the installation of carbon monoxide detectors in your home. An expert technician from MHS/LOMACK Heating and Air can properly install your CO detector and ensure it's functioning correctly.
Zoning Products
Zoning can provide optimum comfort with increased energy savings in your home by dividing a home into areas with similar heating and cooling needs and independently controlling the temperature in each area. Much like multiple light switches that independently control lighting in different rooms, with zoning, multiple zone thermostats or sensors control temperature in different areas of the home. Contact us for an in-home evaluation and estimate.
Thermostat Products
Thermostats are used to turn on heating or cooling systems to bring the home to a set temperature. In addition to basic temperature control, programmable thermostats can be used to manage the indoor environment of your home at different times of the day or week. This type of control can have a dramatic impact on the overall energy use of your home. We carry a complete line of thermostats. Let us help you choose the one that best matches your lifestyle.
