House not Cooling?

We had a question come up today about a home that never seemed to cool off during the day, but would get comfortable in the evening. Couple of things come to mind here.

One possible reason is that the AC is undersized.  This can be figured out by having an HVAC company perform a Load Calculation (measurement of how much heat is gained in the summer & how much heat you loose in the winter from your home). There is special software that is used to help make this determination.  Another possibility is an under charged unit (not enough, or low, refrigerant).  HVAC companies have tools to measure if this is the case.  A Third potential cause of your home not cooling properly is infiltration air (accidential air that does not come from the conditioned space, like an hot attic or the outside).  An HVAC tech can measure the temperature of the air coming thru the AC Coil & determine if this is the case.

There are also other reasons that could cause your home not to cool properly, if you have any questions, give us a call 815-254-5127!

Sizing Air Conditioners Properly

Be mindful that when properly sizing your air conditioning system for your home there are more factors involved than just the square footage of your home.

Your A/C is sized for an outdoor temperature of 88 degrees in the summer. So when it is above 88 degrees your air conditioner is now too small, undersized. You may find that it will run longer to cool your home. If it is older, dirty, and 100 degrees outside than it could be a recipe for disaster.

Cool off your A/C today with a watering from your hose. They get hot too, & it will help the system work better.

Air Conditioner Copper lines (New vs. Used)

Remember having clean copper lines that connect your air conditioner to the evaporator coil (located inside your house connected to your furnace) is one of the most critical pieces of the installation process.

BEWARE OF COMPANIES THAT USE SCRAP COPPER LINES, OLD COPPER LINES THAT HAVE BEEN CUT OUT FROM OTHER JOBS, AND EXISTING LINES THAT ARE CONTAMINATED WITH DIFFERENT OIL, CARBON OR ACID.

Using your existing copper lines on a new installation is okay to do, but it will cost more money to clean them, and if you don’t clean them, you need to replace them. There is only one way to clean them and it is not with nitrogen alone.

With any company you choose, make certain it is listed on the proposal in detail as to if you are getting the line set cleaned or replaced. Should you ever have a problem, this information will serve as proof to the manufacturer of the installation process that was used. Improper install can void the manufacturer warranty.

Problems with Air Conditioner

There are times when AirMaxx is called out to perform a routine cleaning and diagnostic for an Air Conditioner in Plainfield, Channahon, or Minooka Illinois.

The homeowner may suspect that the system just hasn’t been cooling like it used to, or they are habitual in their maintenance process & this is something they do every year.

When we are called to perform such a service, we are performing an evaluation of the air conditioner and cleaning it to perform as well as it can, based on its age and issues.  Older air conditioning systems do often times leak refrigerant and this leaking process can be slow or fast.

We seem to be the ones that gives both good and bad news, and at times, it may be perceived as trying to sell a new air conditioner. I can assure you that we would only recommend this as an option if we feel it is the BEST, cost saving option, for our customers given the age & complexity of their Air Conditioner issue.  Our reputation as a fair & honest company demands this.

We want our customer to be educated on the why our world is effected by the change of the type of refrigerant that is used to power the cooling process of your older home air conditioner.  We have attached an article we believe illustrates it very well HERE.

An educated customer is a our best friend.

Leaking Air Conditioner?

I hate to be the one with the bad news, but a leak is one of the worst things to have go wrong with your Air Conditioner.  I hope it is not that.  I am linking to an EPA article explaining the phase out of R22.  Click Here for EPA article.

Due to this phase out of R22, the price has been sky rocketing.  Every year we get closer to the end (2020).  I do not purchase it anymore, but I due have inventory for warranty situations only.

They do make a substitute refrigerant but it CANNOT be mixed with R22.

I would be glad to diagnose the problem, but it is no longer the days of just recharge it and see if it last until next year, the cost is a waste of your money.

BEWARE OF COMPANIES PUTTING DIRTY OLD R22 FROM OLD AIR CONDITIONS THAT THEY REMOVED FROM SOMEONE ELSE’S HOME INTO YOURS AS A FIX.

The new air conditioners use R410A, it is less expensive but it can not work in R22 air conditioners.

It has been about 8 years since we have installed an R22 system, we only install R410A units.

We obviously service all but a leak on an R22 required more explaining.
Let me know if you need me to check it out.
