Manual J

A Manual J is a process that trained technicians use to accurately size heating and air-conditioning equipment. Often called “Heat Load Calculation” or “Cooling Load Calculation”, tadalafil this process considers factors such as:

  • Local climate
  • Size, shape and orientation of the house
  • Insulation levels
  • Window area, location and type
  • Air filtration rates
  • The number of residents
  • Occupant comfort preferences
  • The types and efficiencies of lights and major home appliances

Using this technique, our technicians will provide you with the correct HVAC size to keep your home cool and dry in the summer and warm in the winter.

Duct Blaster Test

It is estimated that more than two-thirds of American homes have ducts that need sealing or repair. Leaky ducts increase your energy bills, reduce the performance of your equipment and can jeopardize air quality and your comfort.

The average duct system leaks 30% of conditioned air into the attic, crawlspaces or the garage, instead of into the house. Leaks can also pull outside air (hot in the summer, cold in the winter), dust, mold spores and other contaminants into the house.

Our qualified technicians will perform a Duct Blaster test that involves pressurizing the duct system with a calibrated fan and simultaneously measuring the air flow through the fan and its effect on the pressure within the duct system. We will diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify the quality of duct system installation.

We also perform Blower Door Tests. This is a whole house testing system that evaluates not only duct leakage, but also leaks in unsealed cracks and openings throughout the house. With a Blower Door Test, a powerful fan is mounted to an exterior door. The fan pulls air pout of the house, lowering the air pressure inside. This allows our technicians to easily detect areas that require better weatherization and sealing.

Air Flow Analysis/Balancing

As part of our Whole Home approach to heating and cooling, we perform Air Flow Analysis and Balancing. If you’ve found certain rooms in your home to be warmer or cooler than others, it may be because the air in your home is not being distributed properly. We carefully test each vent in the home and listen to your specific comfort needs. With this information he can diagnose, repair and balance the duct system for maximum system performance. The end result is having rooms that are the same temperature, cleaner air, better humidity control and energy savings

Mini Split

Mini splits are ductless air-conditioning or heating systems. They are useful in multifamily housing or as retrofit add-ons to houses with non-ducted heating systems, such as hydroponic, radiant panels or space heaters. They can also be a good fit for room additions or small apartments, where extending or installing distributed ductwork is not practical.

Geothermal Heating & Cooling

Geothermal Heating and Cooling is a clean and sustainable energy source that can save up to 80% on your home heating and cooling costs.

Geothermal technology uses the ground you already own to heat or cool your home. The technology is based around the fact that the ground below the surface of the earth stays at a consistent temperature of around 55 degrees Fahrenheit, year round. To harness this natural heat source a series of fluid filled pipes, called a loop field are laid out 50-100’s of feet below the surface of the home. The fluid circulates continuously inside the buried pipe, absorbing heat from the earth during the winter for use inside your home. In warmer months, the fluid takes heat from indoors and transfers it back into the earth while cool air is distributed throughout the home through a geothermal heat pump.

Since Geothermal Heating and Cooling does not rely entirely on fossil fuels it produces significantly less greenhouse gases. It is also safe, reliable and requires very little maintenance.

Thermal Envelope

What is a Thermal Envelope?

The Thermal Envelope refers to a home’s exterior shell: Walls, foundation, floors, ceiling, windows, doors, and roof. A properly sealed thermal envelope keeps heated or cooled air inside the home and prevents outside air from entering the home. Ignoring holes in the thermal envelope wastes energy, increases utility costs and decreases your comfort.

The most common areas air can escape are:

  1. The attic. The older the home, the more likely it is to be poorly insulated.
  2. Windows. Old window fixtures are responsible for up to 15% of the air lost in the home. There are rebates and tax credits available for window replacement, solar screens, window film, and Low-E glass.
  3. Electrical Fixtures. Any lights or electrical fixtures require wires that travel throughout the house. These wires can cause gaps and cracks in the walls of the home, causing air to escape.
  4. Doors. Gaps in your exterior doors can be the cause for much of your homes air leakage.
  5. The chimney flue.  A badly designed chimney can both let warm air escape the home and draw drafts into the home.
