Frequently Asked Questions:

House Is Not Cooling When I Run Air Conditioning Unit?
Hello - I Have Been Running My Air Conditioning For Several Hours And My House Temp Has Only Dropped Between 1 And 2 Degrees. It Is Not Particularly Warm Outside And The House It About 1900 Sq Feet. Cool Air Is Blowing Out Of The Vents And It Appears To Be Working Normally From The Outside Unit. I Had Recently Put In A New Thermostat And Everything Appeared To Be Fine When We Ran The Heat But I Am Wondering What The Issue Is With The Air And If Anything Could Be Tied To The Wiring Of The Thermostat Or If It Is Probably A Different Issue.

Rather than guessing, I would just make an appointment for a clean and check from an hvac company especially if it hasn't been done this year.
The most common problems are dirt in the system from lack of cleaning or a low or high refrigerant charge.

What Is The Best Type Of Air Conditioning Filter For Home Ac?
Does The Filtering Process Restricts Air Flow For The More Expensive Air Filters. Is It Worth The Extra Money Or Is The $3 Air Filters Just As Good? I Don'T Buy The Blue Ones But Didn'T Know If There Is That Much Value Out Of The Cheaper Wavy Looking Filters.

I use Filtret 300, they get the dust out and flow great but only last three weeks.

How Can A Heating And Air Conditioning Service Technician Find Side Work?
My Employer Doesn'T Allow Side Jobs, But I Need The Extra Money For My Family. What Can I Do?

Join clubs around your area and let the members know what you do. Maybe let them know that if the job isn't too big you give them a hand -- can't take work away from the company, you know. wink, wink...
Make sure the boss or other company members aren't members and it wouldn't hurt if the clubs are across town or in the next town where your company doesn't operate.
By letting them know about the size of the job you leave yourself an out if you actually have to bring the company into play.

What Causes Heat Pumps To Freeze Up?
It Normaly Happens When The Temp Is Around Freezing

That means the unit is not going into defrost mode. Meaning the defrost board is more than likely bad.
The unit may however, lightly frost over, then when needed the unit will go into a defrost state (which is actually the air conditioning kicking in) and it shut the OD fan off. Once it completed that cycle it return to heat pump mode. Thats the crash course version of it.

You will damage the compressor with continued use in this manner if it freezing.

Also make sure your filter is not plugged up. If it was doing this during the summer you have a charge issue. IE leak

What Is &Quot;Fan Coil&Quot; Air Conditioning System And How Does It Work?
Can Anyone Explane How Does The Fan Coil System Work, Just The Simple Explaneation, The Concept, And What Is The Primary Difference From Other Air Conditioning Systems. Thnx

Fan coils are what they sound like. A fan blowing air over a coil. There can be one or two coils - one for heating & one for cooling. Often, an office building can have just cooling on the inside, while areas on the permimeter & top floor need the heating.

So, somewhere in the building, there will be a chilled (cold) water plant that pumps cold water to all the coils, and a hot water system - could be a hot water heater or a heat exchanger connected to a central steam plant - that pumps hot water to all the heating coils.

The fan blows air all the time. When it gets warm, the thermostat opens the chilled water valve, and cold water goes throught the coil, and cools the air being blown by the fan. If it gets too cold, the heating coil works the same way.

The primary difference between 'other' systems is a little more vague. It depends what you mean by 'other.'

A variable air volume system (VAV) will have one or two big air handling units - think giant fan coil - and VAV boxes will control the air to the space, instead of controling hot or cold water.

A central DX system won't have any circulating water.

A heat pump system basically has the coil, but has individual compressors in each fan coil.

A wall unit has it's compressor in the unit, maybe electric heat.

Lots of variations. The big advantage of the fancoil system is that you only need to make room in the ceiling for the water pipes, instead of a lot of ductwork. Fresh air can come in by a more central system with smaller ducts. Usually chilled water is more efficient than using a direct expansion (DX) system. On the other hand, there's a lot more filters to change.
