Not All Air Conditioning Systems Work The Same

They all remove heat from one location and transfer it to another location, but their are thousands of factors that make it run efficiently, quietly and get your home comfortable. 


  • Your furnace works by burning gas into a box or heat exchange while the fan moves air through it. The moving air absorbs the heat which then heats your home.
  • Not all the heat from your furnace is used to heat your home, the excess heat gets vented outside
  • The vent that goes outside also takes out the carbon monoxide produced by burning of natural gas.


  • Air conditioning in its purest form is moving heat from one place to another. For most homes its moving heat from inside to outside
  • It does this with an outside unit (the condenser)  and your inside unit (furnace and fan) and a coil (box above furnace).
  • As the air from your furnace blows air over the coil, the refridgerant inside the coil absorbs the heat and transfers it outside to the condenser where the heat is released outside.

What You Should Know Before Getting a New Funrace or Air Conditioning System

Investment Iceberg

Always Get A Matched System

Not getting a matched air conditioning & heating will kill the life span of the system, give performance issues, and not get the true energy efficiency rating it was designed to get. The only way to tell if it is a matched system is with the ARHI number provided by the government. A matched system is a furnace, coil, and condenser, sized currently for your home and have been tested and proven to work properly together.

You have choices when it comes to home comfort

The old way of getting a new heater or air conditioning system was, just replace what you have existing and everything will work out.  Today technology has change air conditioning and heating industry from just hot and cold air to true indoor comfort.  Some of the biggest benefits with the newer furnaces and condensers are more even air temperatures, less noisy, and more energy efficient. You will be surprised that most contractors do not even ask or inform you about all your options.  Remember your new comfort system is going to working for the next 10 to 20 years.  You want to get something that matches your needs not just hot and cold operation

Variable Speed A/C and Heat

High efficiency heating and cooling units that will automatically adjust the flow of warm or cool air for ultimate comfort.

High Torque ECM

Slow start up when first turned on, which saves energy on startup. Second most efficient design after variable speed.

Two Stage

Two levels of operation which saves energy during non-peak heating and cooling. Runs at lower stage most of the time.

Single Stage

One level of operation with no difference between peak or non-peak heating or cooling demands. Least efficient design.

Start Saving Money With New Tech

The minimum SEER for California is 14

• SEER = Seasonal Energy Effiecncy Rating

• SEER is regulated by the U.S. government

• SEER is the standard for air conditioner efficiency.

• Higher SEER ratio means more money saved on power bills.

• SEER doesn’t measure how fast your A/C will cool down your home, it will just save more energy when it runs.

• A 10 SEER system will cool at the same speed as a 14 SEER system, however the 10 SEER will use up more electricity and money.

SEER Is Like MPG The More You Have The More You Save

How It Is Installed Matters The Most

Horizontal Installation

The NCAEC, a non-profit organization, examined air conditioning manufacturer’s efficiency versus actual real-world install efficiency.

  • Only 10% of all installations met manufacturer energy standards
  • 90% of units tested exhibited some sort of energy wasting problem
  • 50% had an improper refrigerant charge level
  • 40% failed to meet minimum air flow standards
  • 20% were barely inside the range specified by manufacturers
  • A deficiency of only 20% of indoor air flow reduces SEER rating by 17%
  • A 15% return air leak from a 120℉ attic could reduce a 12 SEER to a 6 SEER

The Real Cost

Going cheap is not always the best investment. The systems we install are designed to last 10-15 years without a major repair, and can last up to 25 years if they are well maintained. When you pick out your comfort system think of the long term comfort and energy usage you really want to pay for your home and family.

There are lots of ways to bring down the price. The easiest way other contractors do that is by cutting corners, or not providing you with a complete comfort system your home and family deserve.

Top 10% Installation

We will properly match your equipment to your home’s needs to ensure that you are reaching the true SEER and AFUE rating set by the manufactures. After every installation we perform a 37-point inspection to make sure we did not miss anything. We strongly suggest you get permits with every complete installation. Not getting permits is against the law. Any HVAC contractor that tells you not to get permits, is not doing you any favors. The State of California requires a third-party duct inspection to ensure your system is preforming at 100%.

What is really involved in replacing or installing a new furnace, coil and condenser for your home?

A lot of home owners think that installation of a new air conditioning or furnace is easy. Well, we listed the larger steps needed to replace your comfort system for your home.

Cut-In Installation (Completely New System)
This would be combined with a attic installation, condenser installation and ductwork installation. A cut-in installation is where your home does not have central air conditioning or heating. Where it only has a wall furnace or floor furnace. Most homes in southern California built before 1985 only had a wall or floor furnace. The major things that your home needs to install central air conditioning is a large enough attic (to fit the furnace, coil and ductwork), a 100 amp power panel and or enough room in your main power panel, enough space for the condenser on the side of the house or backyard. Check with your HVAC contractor that now local and state codes before placing you’re A/C system. The items listed bellow is everything extra you need to do to get your new air conditioning installed if you did not have any air ducts or central heating before.

Horizontal Installation

(in attic)

Horizontal installations are common in new homes to save space, the furnace, coil and ductwork go in the attic. They are also common if your home did not have central air conditioning when the home was originally built, and air conditioning was added at some point later. Moving you existing furnace to the attic is usually straight forward and only requires enough space to place the furnace, coil and duct work up there. The advantage of moving your existing furnace and coil from the closet to the attic include saving space, less noisy, new closet.

New Duct Work

Duct work is the most overlooked part of the whole process when homeowners look for a new air conditioning and heating system for their home, however it is the most important component. Did you know that you could have the most expensive air conditioning system on the market but without the correct air flow your homes air conditioning system will never work as it was intended and will cause hot and cold spots, poor performance and waste a lot more energy than it should. What’s even worse most homeowners don’t even know that there is something wrong with their ductwork, because “it still cool the home”. If you have not change out your ductwork in over 20 years and you are replacing your air conditioning system, you should really consider having it looked at by a professional for your peace of mind.
