Furnace Service:  We offer a furnace clean and checks a 28 point heating saftey inspection to make sure your furnace is performing safely and at maximum efficiency. Inspection includes cleaning & furnace air handler and control surfaces, inspection and testing of all safety controls, lubrication and maintenance of serviceable parts, visual inspection of the heat exchanger integrity and an electronic carbon monoxide test to ensure you and your family, renters, or customers are safe during the heating season.

Air Conditioner service: We offer a 31 point air conditioner service inspection to insure your air conditioner is ready to perform during the warmest summer days. Inspection includes furnace blower compartment, evaporator and condenser coil inspections, visual and electrical inspection of wiring and operational controls. Air conditioner service can also include inspection and cleaning of condernser coils, refrigerant check and charge .

Humidifier Service: During the heating season, nothing affects indoor comfort as much as the proper operation of your whole house humidifier. Ensuring proper humidity in your home will protect your home furnishings as well as provide energy savings and comfort. Humidifier service includes checking for proper equipment operation, inspecting for proper water and air flow, inspecting wetting media, and humidistat controls.

 Water Heater Service: Hot water heater life and efficiency can be greatly improved by proper annual maintenance. Service includes inspection for water and fuel supply leaks, draining of sediment from tanks, inspection and cleaning of the burner, orifice, thermocouple and pilot hood. On electric Heaters inspection of thermostat, heating element current draw and power supply. Inspection of tank anode.


Maintenance Service Plan: For Residential, Landlords, and Commercial customers.

Standard Residential Plans include both Furnace and Air conditioning start up inspections.

Commercial Plans can include additional mid-season inspections with quarterly (every three months) filter changes.

We can create a custom maintenance plan with accurate records for your residence, rental home, or place of business.

Service plans can include waived service call fees when subscribed to the Heating and Cooling service plan.

A gas valve over time wears the regulation spring out. This spring can control the amount of presssure to the burner assembly. To much gas can overheat the heat exchanger inthe furnace and cause a premature failure of the furnace. This is a common issue in furnaces. When your furnace was originally installed this should have been check to make sure that during transport the valve was still set at the furnace manufacture specifications.  





To help you when discussing your heating, cooling or ventilation issue.

Annual Fuel Utilization Efficiency. This is a measure of a furnace's heating efficiency. The higher the AFUE% is, the more efficient the product is. The government's regulated minimum AFUE rating for furnaces is 78%.

Air Handler
This is the portion of the central air conditioning or heat pump system that moves heated or cooled air throughout a home's ductwork. In some systems a furnace handles this function.

Balance Point
An outdoor temperature, usually between 30 degree and 45 degree F, at which a heat pump's output exactly equals the heating needs of the home. Below the balance point, supplementary electric resistance heat is needed to maintain indoor comfort.


This is British Thermal Unit. The amount of heat required to raise the temperature of one pound of water (about one pint) by one degree F.

Evaporator Coil
The portion of a heat pump or central air conditioning system that is located in the home and functions as the heat transfer point for warming or cooling indoor air.

Heat Pump

An air conditioner with a valve that allows it to alternate between heating and cooling.

Heat Source
A body of air or liquid from which heat is collected. The air outside the home is used as the heat source during the heating cycle.

Heating Seasonal Performance Factor. This is a measure of a heat pump's heating efficiency. The higher the HSPF, the more efficient the product is.

Seasonal Energy Efficiency Ratio. A measure of an air conditioner's cooling efficiency, The higher the SEER, the more efficient the product is.

Split System
A heat pump or central air conditioning system with components located both inside and outside the home. The most common design for home use.
