SUN STATE HVAC
Enjoys 5 Star A+ BBB Ratings
Most folks don’t realize that the BBB vets and verifies the reviews posted on their Website. Other sites like Yelp including all browser sites like Google and other Social Media Review Websites do not verify reviews posted which allows unverified reviews to be posted as if they were true which allows anyone with a Website to purchase Fake Reviews from companies who provide these fake reviews for a fee!
But the BBB is NOT a Social Media Company or browser Website. They are specifically designed to promote sound business practices strictly for the welfare of the public which is their only interest.
Social media sites have spawned a whole huge underground business where for the right price, companies will provide x number of reviews for x number of $$ which has been going on for a few years now. We know because we keep banning multitudes of email solicitations from these unscrupulous organizations!
The bottom line is, if you depend on reviews to help you choose any business or service, go to the BBB and believe what you see there, but do not believe the fake reviews you find on social media sites – especially those with perfect or nearly perfect dozens or hundreds of 5 star reviews. If it’s too good to be true, it probably is.

Technicians at Sun State HVAC are Highly Rated AC Service Professionals specializing in all types of HVAC Repair Services. We believe in the saying, “Let Plumbers be plumbers, Auto Mechanics be auto mechanics and Air Conditioning Professionals be Air Conditioning Professionals”.
There’s an old saying, “A double minded man is unstable in all his ways”. The wisdom of these words can not be denied.
At Sun State Refrigeration, AKA Sun State HVAC, we are single minded focused on one thing, Air Conditioning and Refrigeration. HVAC is a highly specialized mechanical field and to incorporate other specialized fields e.g Plumbing Services, Water Filter Services, Electrical Services, other Handyman Services and other Fields of Service can only cause what might have been a great company focused on being the #1 Best AC Company to dissolve into, at best, a mediocre multi-conglomerate do-it-all company.
This is why a heart surgeon does not do dentistry and a dentist does not do internal medicine, nor does an osteopath suddenly decide to add delivering babies to his business.
Every specialized field regardless of discipline demands focus on that particular specialty if it is going to be known as being, “at the top of their field”.
Because of these truths we refuse follow the herd of other Valley AC Companies crossing the line into other business types such as those mentioned above which are not directly related to our business of Air Conditioning Repair, Air Conditioning Installation, Refrigeration Repair or other Air Conditioning and Air treatment related equipment.
There are several reasons – especially the larger companies – do this. True HVAC Service Professionals are extremely hard to find, and no offense to Plumbers, but Plumbers are a dime a dozen in comparison, so the big companies hire plumbers (at a discount) to drive their AC trucks and send them out not only to do Plumbing calls but to ALL their calls, both Plumbing and AC.
When they go to an AC call, the first thing they’re looking at is how they might be able to sell you a new AC because they have little to no expertise in repairing something as complicated as your Air Conditioning. If the call is a Plumbing call they can handle snaking a toilet and selling your a water filtering system too. The bottom line is they have to sell something to pay for the hundreds of thousands of advertising dollars they spend a year to get you to dial their number instead of a solid local company like Sun State HVAC / Refrigeration.
It takes a highly specialized HVAC Technician to diagnose your AC system, properly perform a health-check and tune-up, or professionally repair an HVAC system in such a manor that it will purr like a kitten again. We at Sun State HVAC hire only the highest level HVAC service personnel Specialists and our turnover rate proves it. We have employed the same technicians for 5 years going (so far). Check our service areas here, then try us and you’ll see.
We promise to do out best to take care of your needs respectfully – better than any other company. We strive not to be the biggest, but to be the #1 Best AC Repair Services Phoenix has to offer!
If you live or have a business in or close to one of our service areas you are truly in luck. If you’re not in one of our service areas we apologize! We are constantly looking for high level technicians to expand our area coverage, but as mentioned earlier, Sun State HVAC level technician specialists are very hard to find and we would rather be a smaller company with a close to spotless reputation rather than a big company constantly having to hire reputation and internet clean up crews and purchase 5 star reviews like our competitors!
Here at Sun State HVAC we refuse to allow complacency creep into our company by following in the footsteps of other AC Companies just to be able to advertise we do plumbing and sell water filters.
It’s a simple fact that plumbers are not HVAC Technicians or Air Conditioning Specialists. If you would like a professional AC Repair then you should demand a highly qualified HVAC Repair Services Company like Sun State HVAC. You will never see companies like ours advertising “We Do Plumbing” on the same vehicle that advertises “We Do Air Conditioning”. So beware… if the vehicle arriving at your home has the word PLUMBING anywhere on it and you called for AC Services, the chances are great that the technician driving that vehicle is not an Expert AC Service Repair Technician at all regardless of what he or his shirt says!
You may ask, “How can you know if the driver is a real AC Technician?” If the driver/tech’s vehicle has both statements “We do Plumbing” and “AC Repair Service” red flags should be raised.
Before allowing repairs to begin, ask the service tech if they can check your slow draining plumbing while they’re there. If the tech says yes, and he checks and clears the drains – then he is a plumber. Do not let him work on your precious Air Conditioning System!
If the technician says no “I don’t work on sewer plumbing, I’m an AC Tech, then the chances are very good this person is a real AC Repair Service technician.
This is because the only drain systems a HVAC technician will work on is the condensate drain of your Air Conditioning system which has nothing to do with your homes sewer drain system.
Given the training, money and multiple internship years and on the job training required to become a highly qualified HVAC Repair Services Specialist there is no way someone with these qualifications will work on sewer systems…. they just won’t.
It takes a minumim of 5 to 15 years (depending upon aptitude and who the instructor is) to become a seasoned qualified AC Repair Services technician along with intensive training and dedication, much like becoming a Doctor, obviously the only real difference is one works on humans, the other with machinery. There are many so called AC technicians in the world but becoming a highly qualified HVAC seasoned specialist is actually quite rare.
This is not to say that Plumbers aren’t great, smart wonderful people who do an incredibly important job but Plumbing is not at the same technical level as AC Repair Services and any honest AC Repair Services company worth their salt would never mix these two types together in the same business.
Only companies who look for ways to basically fleece the public will do this kind of thing while talking about what their daddy did with a flashlight after buying failing companies that had been previously sold at least a dozen times before.
The temptation to use unqualified personnel e.g. Plumbers and Electricians is because company operators know plumbers won’t be able to repair 90% of the jobs they go on and will opt for selling customers new units even though a cost effective repair might have been performed instead by a qualified HVAC Repair Specialist.

WHAT ABOUT FREE SERVICE CALLS!
News Flash! There’s No Such Thing
Guess what! The amount of customer calls we get telling us that they observed company advertisements stating – FREE SERVICE CALLS – only to find out that that FREE service was not free at all is astonishing. Just ask yourself, why would any #1 Best AC Repair Services in Phoenix Company offer FREE Service’s?
This would be like passing a wagon on the road offering a bottle of ointment that claims it cures baldness, whitens teeth, sterilizes your clothes and shine your shoes for $1 a bottle. In other words, it makes no sense at all!
In fact not only are those service calls not free, they are dang expensive especially considering these companies charge up to 10X or more for the same needed repairs as a Local company like Sun State HVAC, and that’s IF they attempt repairs at all!
You are much more likely to get a full court sales mumbo-jumbo pitch about how your unit is just too old and outdated to repair at a reasonable cost. Then they pull out the old “have we got a special deal for you” sales spiel.
Dear friends, don’t be a statistic! Never use companies that pay multi-thousands of dollars for full page advertisements, TV, Radio spots. Basically everywhere your eye looks or your ear hears you see and hear about them. Also, never call an AC Repair Services company that advertises WE DO PLUMBING SERVICES or MOST ANY OTHER SERVICE other than AC Repair Services, Heating Repair Services or other closely related Cooling and Air Treatment Services.
Stay away from those that offer “deals” so cheap it’s simply too good to be true (FREE this and FREE that) unless of course you want be overcharged and taken advantage of for those services to pay for their exorbitant advertising expenses.
Our HVAC Repair Services
Some of the many services Sun State HVAC has to offer YOU our Phoenix AZ family and friends.
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…
HVAC Replacement
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…

Only Professional HVAC Services
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! Read More…
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.
