Holding A High Standard

Our Work Seems To
Speak For Itself

Trane SlimLine Units

This is a project we did out in Stone Cove. The placement and the size of the condensers were very
important to the client not to impede on their beautiful landscape. The customer elected to go with the
SlimLine units for a sleek and clean look!

Carrier Furnace

This is a project including the many options you can add to your Carrier system to ensure you are
breathing the cleanest air! Attached to this 96% furnace is an infinity Air Purifier, this is a Merv 15 rated filtration system it uses Captures & Kills technology to inactivate 99% of select air born pathogens trapped by the Merv 15 filter including Corona Virus, bacteria, and other pathogens.

Daikin Condenser

This is a picture of a Daikin Ductless Condenser, in this home we installed 3 zones which fed to this 1)
outdoor condenser. Ductless systems are a great option when you do not have the sufficient clearance
for attic or basement ducting and registers. You also have the convenience of using only one zone at a
time heating & cooling only the space you are occupying.

It is recommended that you have your Heating and AC system serviced twice a year. Once before the cooling season and once before the heat kicks in. This will assure your unit is working at its highest efficiency, saving costs on your energy bill as well as lengthening the life of your system.

It is not uncommon to need a “top off” when having your routine system services, but if there is significant loss a leak diagnosis is necessary.

If your Heating and Air system is the culprit of your energy bill going up it could be a few different things: Lack of maintenance, dirty filter causing air flow restriction, or low system efficiency. If your system has been properly maintained and filter changed every few months and efficiency is the issue – it is time to consider upgrading to a new system.

Yes, we sell and install a variety of WiFi thermostats. These thermostats can be controlled by phone or computer adjusting the temperature of your home allowing you to be in control 24/7.

More About Us

Patriot Heating & Air

The spark was ignited in 1994 when Paul Johnson a Military Veteran, freshly out of the United States Marine Corps, embarked on a new chapter of his life. Paul and his wife Dianne relocated from Camp Lejeune to Arizona where Paul attended Universal Technical Institute, graduating with honors in Heating, Air Conditioning, & Refrigeration. At age 22, he was new to the heating and cooling industry, but knew he wanted to master the craft of this service business. After accumulating several years of technical school and on-the-job training, the Johnsons relocated to San Diego and launched Johnson Air Systems in 1999. Paul and his wife Dianne grew their company one service call at a time with their core values of integrity, passion, pride and gratitude for customers and employees alike. Focusing on residential and light commercial, sales, repair, installation, and maintenance, Johnson Air developed a word-of-mouth reputation for being a fair priced and honest heating and air conditioning contractor. The Johnson family business has grown over the years servicing thousands of homes and businesses, keeping their core values at the center of operations. After 25 years in San Diego, now that their 4 children are grown, Paul and Dianne started a new chapter.  They have relocated to St.George Utah and launched Patriot Heating & Air.  Bringing over 30 years of heating, air conditioning, and wine cooling experience!
