Split System Air Conditioners


Similar to how a refridgerator works, air conditioners transfer heat from inside your house to oustside. The evaporator coil and condenser work in tandem to create a nice cooling enviroment to keep your home comfortable year-round.


Air Cleaners

Maytag Media Air Cleaner

The high-efficiency Media Air Cleaner removes particles down to 0.3 micron – that is a 1/84,000 of an inch! Clean air in your home is important for the health of your family.


Ductless Mini-Splits

mini split ductless fujitsu

With a ductless system, simple copper tubing and electrical wiring to indoor units connects a separately installed outdoor unit. Refrigerant is pumped from the outdoor condenser coil and compressor through the tubing to the indoor unit or units.


Whole Home Humidifiers


The Whole-Home Power Humidifier adds moisture to the air, brings up the relative humidity in your home, increases comfort and can reduce your heating bill.


Split System Heat Pumps


A heat pump is an air conditioner that contains a valve that lets it switch between "air conditioner" and "heater." When the valve is switched one way, the heat pump acts like an air conditioner, and when it is switched the other way it reverses the flow of the liquid inside the heat pump and acts like a heater.

Zoning System


Creating separate comfort zones gives you complete control of airflow. Only when airflow is needed in a certain zone (depending on climate conditions and activities during the day) is air sent to that zone.

A Few Tips For Heating & Cooling Efficiently

As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills — and your comfort. Take these steps to increase the efficiency of your heating and cooling system

Change your air filter regularly

Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

Tune up your HVAC equipment yearly

Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. 

Install a programmable thermostat

A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.

Seal your heating and cooling ducts

Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house. Ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent — and sometimes much more.

Consider installing ENERGY STAR qualified heating and cooling equipment

If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading,consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by more than $115. But before you invest in a new HVAC system, make sure that you have addressed the big air leaks in your house and the duct system. Sometimes, these are the real sources of problems rather than your HVAC equipment.

Ask about Proper Installation of your new equipment

Replacing your old heating and cooling equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent - costing you more on your utility bills and possibly shortening the equipment's life.
