Importance of Home Owner Filter Maintenance

Checking your filters is not only important in the summertime but it is also important to check their status in the winter.  Leaving your filters unchecked can cause all kinds of problems including poor equipment efficiency and higher electrical bills, insufficient cooling or heating into the home, icing up of the system evaporator coil during cooling operation and severely dirty filters can even cause outright system failure on several levels

While performing a system check on a unit that according to the customer was producing ice on the pipes going into the unit outside (known as a split system AC) saying, “the unit is not blowing any cold air.”

While in the home in one of the hallways, I noticed a filter grill high up on a wall at about the 8 foot level.  From below you couldn’t see the filter inside it because the angle of the register grill fins was blocking any view to the filter inside so I grabbed an 8 foot ladder and took a look.

Dirty Air Filter LG

As you can see what I found was not only a dirty filter but one that was noticeably plugged.

Once removed and replaced with a clean new one, the unit immediately began efficiently blowing cool air into the home again.  There’s no telling how much money this one little oversight might have cost a customer in electrical usage alone since when asked, they could not seem to remember the last time they did a filter check on this unit.

Just remember, the first line of defense for any home equipment is YOU the home owner.  Take a little time to learn about your equipment and what it’s basic maintenance needs are and you’ll be far head of the crowd when it comes to smooth trouble-free equipment operation for your home.


New Unit Problem Resolved

Hi everyone,

I felt like writing a post regarding an unusual problem we ran across in the last couple weeks.  A couple months ago we replaced an old worn out unit in New River, AZ and everything went well with the install.  Then we received a call about a month later stating it appeared the unit was hesitating every time it started up.

While there we checked everything out and found on this brand new unit and found a weak  Run Capacitor!  Now this is a brand new unit so who would expect a new unit would have a bad part?  Well I hate to break the news  but AC units are very similar to cars and yes, sometimes we can buy a car or AC unit and find there is a faulty part on it.  That being said, the good thing about a new AC unit is, THE WARRANTY!  We replaced the failed part with a new one, the unit is running ‘like new’ and there was no charge for the call or the part so all in all everything is right again in New River Arizona.

This goes to show you that nothing can be overlooked when hunting for a problem especially on a new unit.  Well, we replaced the capacitor and added a Compressor Start Kit to up the integrity of this unit.  Normally only the more expensive units come with Compressor Start Assist Kits but we felt it would be nice to add this feature to our customers unit, and we did it all at no charge to the customer!  We say, why not?… we installed the unit and our customers deserve to have the very best possible without spending an arm and a leg.

That’s it for now… will be posting again very soon.

Have a comfortable week!

Changing of the Seasons

Hi folks, the summer is finally about to leave us which means a beautiful fall is about to take place with the breaking of beautiful dessert autumn colors and holidays ahead.

With fall though comes the due diligence of evaporative cooler maintenance which is very important for the longevity of your expensive evaporative cooler system.  Without maintaining it before the colder weather hits, when temperatures drop below due point most every day and especially evenings, the inside of your evaporative cooler will become and remain wet causing an extreme shortening of the lifetime of every part of that evaporative cooler including an expensive motor.  It is also important that all the bearings are properly lubricated to keep them from corroding through the winter months which tears them apart on the first start up in the new year.

We at Sun State Refrigeration are born and raised right here in Phoenix Arizona where evap cooling has always been a way of life so we know how to maintain your evaporative cooling system as well or better than anyone in the business.

Call Sun State Refrigeration today and have your evap cooler professionally winter maintained by one of our evaporative cooler specialists so you can keep your valuable investment running like knew throughout its lifetime, 602-867-9480.
