Green Energy Services - Residential

“Green” Energy Services includes not only the use of renewable and non polluting energy sources. It also includes the implementation of Energy Conservation Opportunities whenever possible to reduce a client’s carbon footprint and energy consumption.

Carbon Footprint
For every KW (kilowatt hour = 3414 BTU’s) reduction it eliminates 0.524 lbs of carbon dioxide (CO2) from being released into the atmosphere. This helps the environment in a couple of ways. First it reduces CO2 pollution and it also reduces the electrical demand on the local utility.

For every gas therm (approximately 100 cubic feet of gas, or 100,000 BTU’s) reduction it eliminates 13.46 lbs. of CO2 from being released into the atmosphere. Not only does this help reduce pollution and help the environment it also reduces our dependence on imported natural gas.

Joint Venture
Mechanical Air Service has had a long history of providing energy conservation opportunities for its clients and conducting certified energy audits. From 1979 to 1985 Mechanical Air Service was the exclusive installation and servicing contractor for a Utility Load Demand Reduction Program joint venture between Pacific Gas & Electric, Honeywell and Motorola. This volunteer program provided commercial businesses with a proprietary radio controlled HVAC load demand controller

When PGE’s load demand increased to near maximum levels they would send a radio signal to the Motorola receiver mounted on each units new control panel. The signal activated the internal controller which would raise the thermostat setpoint 1 degree per hour until a maximum temperature of 78 degrees was reached.

The program was a success and further established Mechanical Air Service as a leader in the energy conservation field which was the early beginnings of the Green energy industry.

Below is a partial list of “GREEN” Energy Services we provide:

Commissioning Services
Most residences have HVAC systems installed that have never been properly commissioned to verify they are actually delivering the stated energy efficiencies. Significant amounts of energy can be wasted if a system is not operating properly. Our detailed commissioning services provide real time data regarding actual system performance versus what the client expected and verification of the actual energy rating of the installed equipment.

Duct Testing
Research has shown that residential HVAC duct systems leak 10% to up to 50% of their related airflow resulting in tremendous amounts of energy being wasted. Our state of the art diagnostic and testing procedures can easily identify those leaks so they can be repaired. We believe clients should be able to use all the heating and cooling they pay for.

Home Leakage Testing
Our state of the art equipment can determine the actual leakage rate of your home and determine where the most significant leak areas are so they can be sealed. This can help save a great deal of energy, make your home more comfortable and reduce the potential of unwanted contaminants from being sucked into your home.

Duct Cleaning
Duct cleaning can also be a way to save energy. A clean duct system, clean heating and cooling equipment and clean cooling coils all help reduce the energy needs of your home.

High Efficiency Heating & Cooling Equipment
One of the easiest ways to reduce your carbon foot print and save on your utility bills is to always use the highest efficiency equipment available. Also be aware that poorly installed high efficiency systems will not save any energy. Utility rates for both electricity and gas are constantly going up and the return on investment for high efficiency equipment is short.

Heat Recovery Ventilators
These are effectively used to improve indoor air quality and help reduce the negative air pressures in a home caused by bathroom exhaust fans, laundry exhaust, clothes dryers and cooking exhaust. The HRV transfers the heat content (no contaminants) of the exhaust air to the new replacement outside air. This reduces the need to heat or cool any make up air or infiltration air entering the home when there is a negative air pressure present. Air that infiltrates into your home can contain mold spores as well as other unwanted contaminants.

Hybrid Heating Systems
A hybrid heating can also be referred to as a dual fuel heating system. It is comprised of a high efficiency gas furnace and a high efficiency heat pump air conditioning unit. The heat pump is simply a reverse cycle air conditioner. In the cooling mode it removes heat from inside your home.

In the heating mode it removes heat from the outdoor air and transfers it to the inside of your home. Most people don’t realize the outdoor air has a sufficient amount of heat capacity down to approximately 17 degrees to heat your home.

The hybrid heating system has the ability to use gas for heat or electricity to power the heat pump to create heat. This would depend on which fuel source is the most cost effective.

A hybrid heating system is an excellent match for a home with a Solar PV (Photo Voltaic) system. The inexpensive energy produced can be used to operate the heat pump.

Ultraviolet Light Systems
High intensity dual bulb ultraviolet light systems are very effective at killing mold spores, bacteria and viruses. In addition, when installed properly they help keep your cooling coil clean and eliminate the normal bio-film that can grow on a cooling coil which reduces its efficiency.

Economizers (Free Cooling)
Fresh air economizers have been in use in the commercial market for decades. Their use in residential homes is gaining popularity because of high energy costs and concern about the environment. Substantial energy savings, reduced compressor run time and improved indoor air quality in the home are some of the benefits.

Radiant Floor Heating Systems
Radiant heating which uses low temperature water, approximately 105 degrees depending on how it’s installed and the thermal factor of your floor coverings is typically 30% more efficient than a high efficiency heating system. Warm water is circulated through tubes in the floor or under the subfloor to gently warm your home with no drafts or moving air. Radiant heating is the primary source of heating in most European countries because the utility costs are so high. Radiant heating can be used in new construction as well as when remodeling. An additional benefit is the self adjusting of its water temperature based on the need in the home and the outdoor temperature. Whenever obtaining bids for a radiant system be sure the contractor has a C-4 (Boiler, radiant heat/hydronic heat) California Contractors license and is a member in good standing with a radiant industry trade/education organization such as the Radiant Panel Association (RPA).

Solar Thermal
Solar thermal (hot water) systems have been used for centuries to heat water. Technologies are such that significant savings can be had by installing a solar thermal system to heat your domestic hot water. Utilizing a renewable energy source for this purpose is very cost effective.

Homes with solar hot water panels can significantly decrease the cost to operate a radiant floor heating system when both systems are integrated.

Solar PV
Photovoltaic solar systems are an excellent way to harness the renewal energy provided of the sun. Whenever the sun is shining the panels are generating electricity. The generated electricity is converted through an inverter to be compatible with the power requirements of your home. Excess generated power is fed back into the utility grid causing your meter to run backwards. When the sun is not shinning your home draws power from the utility grid. The utility grid acts as a type of power storage system.

Hydronic Heating Systems
This method of heating circulates water through hot water coils in air handlers (fan coils) in your home or business. An additional benefit is the self adjusting of its water temperature based on the need in the home and the outdoor temperature. Whenever obtaining bids for a hydronic or radiant system be sure the contractor has a C-4 (Boiler, radiant heat/hydronic heat) California Contractors license and is a member in good standing with an industry trade/education organization such as the Radiant Panel Association (RPA).

Heat Reclaim (Free Heat)
Heat reclaim can be a highly effective energy saving option. This system captures the heat rejected from the air conditioners or chiller which would normally be discharged to the outdoors and sends it to the pool, the radiant system, hydronic heating system or domestic hot water pre-heat. Any or all of these things can be combined in a heat reclaim system with the proper controls.

Thermal Energy Storage
Thermal energy storage is an effective method for shifting up to 2/3 of the HVAC load in a home to after hour’s non peak periods. This is particularly effective when the home is using a time of use electrical meter such as when a solar PV system is installed. Current research and development will soon bring these systems to the high end residential market.

Micro Co-Generation
A significant amount of research is being done in this area to provide distributed co-generation systems for large homes. Currently systems are being tested using gas driven (extremely quiet) electrical generation as well as fuel cells. These systems are very efficient at generating electricity and provide waste heat recovery for heating the home.

We are a certified geothermal heat pump installer. Geothermal systems are very energy efficient but expensive to install. The typical payback period for a geothermal system installation is 12-15 years. These are very environmentally friendly systems.

Thermal Imaging
Through the use of our sensitive thermal imaging equipment we can identify heat leakage in a home or office building, poor insulation, roof leaks, moisture hidden in walls and moisture in foundations. Thermal imaging has the ability to view the thermal characteristics of electrical breakers, motors, loose wires and other electrically related items that are beginning to fail. This allows for replacement of the item prior to its failure to eliminate downtime. We also utilize thermal imaging to verify radiant floor heating systems are operating correctly. Our camera can even see the thermal characteristics of a radiant heat circuit in concrete.

Environmentally Friendly Freon
Although all air conditioning equipment, as of January 1, 2010, is required to use the environmentally friendly refrigerant R-410A we were an early adopter of this refrigerant in 2003. We are early adopter of other technologies that benefit our clients.
