Sun State HVAC was born out of a desire to offer Phoenix Arizona a family friendly HVAC Repair, Residential Air Conditioning & Heating Repair and Service Company while also providing needed services to the Refrigeration needs of Commercial Restaurants in the areas.  Sun State HVAC was founded in 1979 by Phoenix Native Veteran Mark Gresin.  

Born of parents both who during the difficult times of the WW2 era  immigrated (legally) to the US, first his Father from Latvia Russia  and later his Mother from Rome Italy.   After some trials, and travels and travails which includes the great depression they were in search of new beginnings and after arriving in Phoenix, AZ they finally found the new beginning they were looking.  After opening a delicatessen bakery and fresh meat food business which was named Gross’ Delicatessen after my Grandfather, it became a quite successful ‘place to be seen’ establishment from the early 30’s all the way up until the early 80’s which is when my parents decided to finally retire.

The 30’s was very hard, our parents lost everything in the Great Depression.

Like many families during that period of time, our parents lost pretty much everything they built and had before that awful economic time.  Afterwards our entrepreneurial family consisting of my Father and Grand Parents left their home in Harrisburg PA cira 1930 and headed West until they came to a small town known as ‘the Valley of the Sun’ which was of course
At that time Phoenix, Arizona had a population of around 50,000 (total) but it was a fast growing city almost doubling it’s population through the 20’s.  Phoenix was a place where anyone with a dream and some drive could stake their claim to the American Dream especially if they could stand the heat!  See… How people stayed cool in the early Phoenix days. 



AC Repair

It is a well-known fact that summer temperatures in our ‘Valley of the Sun’ often soar above 115 deg F and even crossing above the 120 deg F area is not unheard of!

This kind of heat can be devastating to those who have never experienced it before and many valley residents experience forms of anxiety as a result.

Winters in the area are for the most part quite mild. Because of this newcomers to Phoenix AZ often don’t realize how important a good HVAC Repair Services is to have a properly maintained  well-operating air conditioning system until the summer hits and we get the seasons first very warm weekend.   Read More…

Heating Repair

Dear Phoenix, Scottsdale and other Valley area friends (see service areas).  It’s true that winters are mostly in the Phoenix Az area and in fact, they are for the most part simply gorgeous, full of sunshine with the smell of desert sage, orange blossoms, and gardenias in the air.

In fact normal winter temperatures rarely fall below the low 30’s but on occasion can fall into the high teens but even so, because of the area’s low humidity, 30 degrees can actually feel much, much colder, also when it’s really dry you can feel bone-shivering chills even at temperatures up into the ’40s and above! Our HVAC Repair Service is designed to keep your AC and Heating working at its optimal best!  Read More…

HVAC Maintenance

Sun State HVAC has been the forerunner in HVAC Repair Services and AC Maintenance since it’s inception in 1979.  In fact, we practically invented the whole HVAC preventative maintenance process before other companies even realized the importance and value of HVAC maintenance to the customer.

Since most of the bigger companies  have a greedy focus on unit sales, many  use high dollar advertising to pull unsuspecting customers into sales funnels and once in your home, spring sneaky sales tactics to close high dollar unit sales deals because they know you are suffering without AC and are then likely to say yes to ANYTHING!  Read More…

Properly maintained AC units can last a very long time but as the old saying goes – nothing lasts forever.

When the time comes to replace your existing AC, Sun State HVAC has the highest qualifications in HVAC Repair Services and can install most any brand available for you.  But how do you know it is time to replace an existing older unit?   There are several factors involved in making this decision but to make it as simple as possible here are a few checkpoints we look for.  Read More…

AC Repair, Heating, Air Balance, Refrigeration and HVAC Repair, is all we do at Sun State HVAC and we are experts at it.

It’s not easy to find truly great AC Repair Technicians and those who do exist require and deserve a decent income.  Because of this many of the formerly advertised HVAC Repair Services companies have suddenly become plumbing specialists! They now even advertise “Plumbing and Air Conditioning instead of the other way around, making Plumbing their primary source of business!   A wise man might say, let auto mechanics be auto mechanics; doctors be doctors; plumbers be plumbers, and HVAC technicians be HVAC technicians!

Restaurant HVAC-R

Providing Repair and Refrigeration Services to Restaurants so they can meet the strict city, state and local codes and keep refrigerated and frozen foods, beer and wine at safe refrigerated levels, has been the backbone of Sun State HVAC since its inception.

HVAC Repair Services in the Restaurant Service field was literally born as a direct relationship of the founders 30 years of restaurant operational experience and food handling background by way of being born to parents who owned and operated a family Delicatessen, Restaurant and Fresh Meat business for 52 years right here in Phoenix AZ.  Mark Gresin says –  Read More…
