All manufactures life expectancy of central heat and air systems is around
12-15 years. You may say, mine is older than that and running fine.
That may be true, but it may be a wise investment to replace it with a new
higher efficiency unit.
You could be saving $40.00 for every $100 dollars spent on heating or cooling with a higher efficiency system.
The greatest energy usage in your home is your central heat and air system.
Even the least efficient air conditioning system available today is nearly 33%
more efficient than just 8 years ago. Furnaces were generally 78-80% efficient now
they are available at 90% plus.
After you have scheduled an appointment. An individual will come to your home and talk with you and do a survey to find out if for example you have any hot or cold rooms, allergies etc. After the survey they will take some measurements of your home window sizes, what your walls are made of, how much insulation is in your attic, etc. With this information we will be able to do a load calculation to be able to size your unit to your home. After that we will show you some of our comfort equipment. We will contact you after we design a home comfort system for you. We will give you our proposals for you to look over and decide which one you’d like to have in your home. It’s that simple. Give us a call today! (530)401-1102 or (530)823-0363
When you shop for a new furnace or air conditioning unit there's a good chance you'll get confused. You'll hear different names, numbers, abbreviations and acronyms used to describe the capacity and efficiency of the equipment.
The Federal Energy Standard Act was enacted to help clear up some of this confusion and to give a homeowner some basis of comparison between different heating and cooling units. Two terms you hear quite often are the SEER and AFUE rating.
The SEER (Seasonal Energy Efficiency Ratio) describes how much heat in BTU's a particular air conditioner will remove for each watt of electricity it consumes. Since you pay your power bill by the watts you use, the higher the SEER, the less your electric bill.
The AFUE (Annual Fuel Utilization Efficiency) is an average of how much heat a furnace delivers for each dollar you pay for fuel. So, again, the higher the AFUE, the lower the heating bill.
Duct testing is checking your air ducts for leaks. How they are tested? Your ducts will be tested with a calibrated fan that will tell the technician exactly how much air is being leaked throughout your ductwork. First, the technician will have to temporarily seal all the supply registers and the return grill. At the return grill the technician will attach the calibrated fan and pressurize the ducts. The technician performs the test and with this information the technician will learn how much air is escaping from the ducts. On a new duct system, not more than 6% is allowed; on a change out of a system not more than 15% is allowed. Anything over this is a failure. The ducts have to be sealed and tested again. The average home‘s ducts leak around 30 % of the conditioned air outside the home. These leaks are wasting your hard earned money.
Duct testing is required by the State of California if you are installing a new heater, air conditioner, or heat pump or replacing an existing heater, air conditioner, or heat pump in certain climate zones. All the areas we service do require duct testing. This new regulation is required and the building department is enforcing this regulation. There are a few exceptions to this regulation. This testing has to be done by a third party. They are called H.E.R.S. raters. For more information you can visit the energy commission’s website at www.energy.ca.gov/title24/changeout or give us a call.
We offer various maintenance options for our commercial customers. One time, monthly, quarterly, semi-annual, annual, filters included, filters extra, whatever you needs we can accommodate them.
HERS = Home Energy Rating System
A HERS rater is serving as a “special inspector” for the building department. They are certified by a HERS provider.
The job of a HERS rater is to rate homes for energy efficiency or compliance. They do ratings on new and existing homes such as add on or replacement of HVAC systems; alterations; additions; or energy audits. They also do field verification and diagnostic testing for third party inspections of Title 24 energy features.
Think of ducts as tubes that carry conditioned air from one place to where you want it supplied in your home.
The ducts are usually in your attic or in under your floor in the crawl space. They are hidden and you can’t see them.
PG&E has a PDF document that explains this: http://www.pge.com/docs/pdfs/res/rebates/duct_testing.pdf.
The reason you would want to have them tested is because a lot of them have leaks. Studies indicate that duct leakage can account for as much as 30% of total house energy loss. Just as important, duct leakage can prevent heating and cooling systems from doing there job properly, resulting in hot or cold rooms, and humidity problems. Worse yet, duct leaks can create air quality problems by pulling pollutants and irritants directly into the house, think of your ducts as your garden hose. If there is a leak in your hose it still works but you won’t have as much water as you want and you waste that leaking water. In your ductwork the conditioned air is being wasted in your attic or under your floor.
Your ducts will be tested with a calibrated fan that will tell the technician exactly how much air is being wasted throughout your ductwork. First, the technician will have to temporarily seal all the supply registers and the return grill. At the return grill the technician will attach the calibrated fan and perform the test. With this information you will learn how much air is being wasted. Then they may recommend having the ducts sealed or repaired. Then you will have a more efficient system because you will get all the conditioned air you paid for in your house and not be dumping that air into your attic or under your house.
Radiant heating systems use water to move thermal energy from where it is produced to where it is needed. Radiant heating systems are gaining in popularity because they provide a high level of comfort and they are a very efficient system. Potential savings of up to 40% in energy cost compared with forced air systems.
Radiant heating provides even comfortable warmth as there is less air movement with this type of system. There are no drafts with this type of system unless it is through the building itself. The floor is warm to the touch.
The picture below shows tubing on the slab before concrete has been poured. This will be the floor the building will be built on. The water is heated with a flash water heater or a conventional water heater and circulated with a small pump. A typical room thermostat is in the space and controls the temperature.

Benefits
Radiant floor heating provides even, comfortable, warmth as there is less air movement with this type of system. There are no drafts with this type of heating, unless it is through the building envelope. The thermal mass (concrete floor) evens out the temperature fluctuations. The floor is warm to the touch.
Quietness
The system is quiet because a properly-sized circulator pump, used to slowly move the water, is almost inaudible. The loudest sound in the system is usually the gas or oil burner.
Room Function
Hydronic radiant floor heating is virtually an invisible system. Without baseboard heaters, forced air registers etc, furniture layout is not restricted by the heating system. Bathrooms or special use areas with hard floor finishes are well suited to this type of heating.
Lifespan
While the heat source in a properly maintained system can last for as long as 30 to 40 years, PEX pipes set in the floor are expected to last more than 50 years. (Some test results indicate life expectancies of 200-300 years.)
System Components
There are three components to this heating system: a heat source, a distribution piping system and controls. The heat source in hydronic radiant floor heating is usually a boiler or a hot water heater, but other heat sources can be used too. The energy used to heat the hot water can be natural gas, oil, electricity, propane, wood or solar hot water collection.
A circulator pump near the water supply manifold
moves the water from the mixing valve to the supply manifold into the distribution
piping system (tubing) inside the floors.
To select how warm or cool a room or home will be,
controls are required to set the system to a particular temperature. A manifold
system with thermostat is typically located in an accessible wall cavity provides
a series of simple valves that are used to regulate the flow of water through each
zone.
