Have you even seen your roof cavity?

We have. Every time we move into the attic to fix a heater or an air conditioner, we see the dust all over, covering everything to the extent that sometimes it makes it difficult to even breath properly.


But have you ever wondered what effect the dust has over the heater and air conditioner?


Unfortunately, you are paying the cost without knowing the original reasons.

All you see is the direct problem or the failure: the electronic board is down, the fan motor must be replaced...etc.


But what's actually causing all these failures and forcing you to pay considerable amount of money is one main untold source: the dust.


But where is all this dust coming from? You may wonder.

Two sources: from outside and from insulation.

Roof tiles are far from being air tight and the wind blown onto the house will pass through the tiles holding with it dust particles. Furthermore, the fiberglass insulation spread loosely over the plaster will break into fine particles that will join the dust coming from outside.


When the heater is running, it sucks enough air to burn the gas; this dust-loaded-air will eventually dump its payload over the unit's electric and electronic parts.


And the result?

Briefly: slow death.

Overheating many of the electronic elements, dust will eventually shorten their life expectancy.


Short circuiting is an another main reason happening to the wiring connections which will sooner or later cause a sudden failure.


Suffocation is a third reason, where dust coats the motor windings preventing it from proper ventilation leading again to overheating and failure.


Enough of failure reasons, right?... let's jump into the remedy.

It is simple, every year manage to have a preventive maintenance for your unit. Dust blown out of the machine, electrical connections checked and re-tightened and fan motor cleared from dust.

This must be done twice a year or at least once before winter season starts.


Bottom line, allowing a yearly check-up will save you a lot of money and cold annoying days. Many air condition contractors aren't into preventive maintenance but as experts in maintenance management and engineering, we say that this is how things should be done properly.


Preventive maintenance saves time and money and is always the right way to extend the life of your heater.

Paying a relatively reasonable amount of 150$ for a yearly maintenance intervention is surely more adequate than waiting the unit to fail.
