4 Things To Consider When Choosing an HVAC System


Efficiency ratings are like gas mileage, the higher the rating, the more efficient the product. All products are given the following ratings, so you’ll know exactly what to expect from your investment.

The Infinity 96 Furnace will use about the same amount as a 100 watt light bulb during low-capacity heat and continuous fan operation.


Home comfort shouldn’t come at your ears expense.  Many different manufacturers offer a wide range of air conditioning units with 75dB or lower.  There are some that are even as low as 68-69 dB.  You can compare this rating to common household items to get a better sense of what those numbers mean.

Lawnmower                                110dB

Washing Machine                         80dB

Hairdryer                                      75dB

High Efficient Air Conditioning  68-69 dB

Freon 22 Refrigerant. Since it’s debut in 1930, Freon refrigerant has been used in cooling systems. The Clean Air Act of 1990 prohibits the production of Freon-22- based air conditioners and heat pumps by 2010,  and Freon-22 production by 2020. As Freon-22 productions declines, it’s cost is predicted to rise.

Puron refrigerant; Carrier Corporation was the first to introduce a new, non-ozone-depleting refrigerant called Puron. Puron refrigerant is chlorine-free, so it doesn’t damage the Earth’s ozone layer. As other refrigerants become less available, Puron refrigerant will be the refrigerant of choice for years to come.

Frequently Asked Questions

What does HVAC stand for?

Heating, Ventilation and Air Conditioning

How often should I have my equipment serviced?

Heating and Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring.

We recommend that you change your filter regularly, depending on the type of filter you have. Changing your filter regularly can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a severe breakdown. A Nor Cal Mechanical Service Partner Plan is your assurance that these maintenance needs are met regularly and that any potential problems are promptly identified.

How can I increase the efficiency and life of my home’s heating and cooling systems?

A few quick tips:

  • Clean and replace your filters frequently.
  • Your system will heat and cool more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home and allows for better filtration.
  • Install shades, drapes, shutters, or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels.
How do I know if my system is working properly?

Is it making strange noises?
Is it cooling or heating all areas of your home sufficiently?
Has it been taking longer to cool down or heat up?
Have your utility bills been rising for no apparent reason?

Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to contact Nor Cal Mechanical to check out your system whenever you notice anything out of the ordinary.

Is there anything I should check prior to calling for service?

Check to be sure that the air conditioner or furnace is turned on. Check that the breakers and the disconnects are turned on and be sure the thermostat is set correctly. Also make a note of any strange noises or smells.
