A/C Installation:

Many people opt for professional a/c services when they wish to set up a brand-new Air Conditioner in their office or homes.

Frequently Asked Questions:

My Air Condition/ Furnace Is Not Blowing Any Air When I Turn The Heat On. It Is Not Even Getting Hot.?
I Turn The Thermostat On And My Furnace Starts Making A Low Humming Noise. Even After An Hour, There Is No Heat Coming From The Unit And It Is Not Blowing Any Air. If I Turn The Ac On It Works But Not The Heat. I Live In Massuchesetts And It Is Getting In The 50S Now. If It Helps, I Have An Armstrong Air Conditioner, Model # 48Hwc24a-23.

If you have a pilot light, it is not lite or if you have electronic ignition it is not working or :

Do you have the thermostat set to "HEAT"?

With heat the fan will not blow until the heat chamber is to a certain temp, so no fan without heat.
The hum you hear is probably the small fan that exhaust any fumes in chamber before main comes on.
I'd say a faulty ignition syatem.

Hv Ac Question: Dirt Crawl-Humidity Levels?
I Have A Dirt Crawl Space. I Have Just Covered The Dirt With Some 5Mil Plus Thick Professional Landscape Fabric To Keep The Furnace Intake From Taking In So Much Dirt. Should I Be Re-Routing The Intake To An External Air Source? Also, Should I Be Putting A Dehumidifier In The Crawl To Keep The Humidity Down?

I think you need to check your filters or have someone check to see if the furnace is installed properly. It is hard to do more that describe general conditions without seeing your system and what level of humidity you are dealing with.

Landscape fabric is ment to keep weeds from growing. It is also ment to let moisture through. You would have been far better off doing the same job with 4 or 6 mil plastic. The appropriate treatment for a cawlspace in modern construction is to place plastic and then cover it with concrete. Additionally the space should be ventilated in the summer months at least to keep humidity from building up and rotting the beams.

That said your question was about a furnace or a furnace / ac (evaporator in the crawlspace. The furnace has two separate air systems. (If it is not electric) One system should have the air return within the living space. Ductwork should go from that return vent, through filters and then to the furnace. After it passes through the heat exchanger in the furnace (there is no heat exchanger in an electric furnace) the warm air should go through ducts into registers in the rooms. This system is closed to the crawlspace unless there is a break in the ductwork. The filters in the return air duct, probably near the furnace, should be changed as often as once a month.

If you have air conditioning. The air flow is the same as the heating system. Attached to the furnace but in the supply air flow will be a coil that is attached by refridgerant tubing to an condenser outside. Some AC systems have an optional "economizer" unit on them. This is intended to bring 10 to 30% outside air into the airflow. It should not bring crawlspace air into the airflow. It should have a separate small duct to the outside.

The furnace has to be powered. If its "fuel" is electricity there is no need for a chimney. If the furnace is burning gas or oil for heat it is necessary for the furnace to have sufficient air for combustion or it will produce carbon monoxide, a deadly gas. If the space where the furnace is located is enclosed "make up" air will be provided by a vent or a duct to the outside. This air is burned and does not mix with the air that is going to the living space. It goes up the flue.

How Does One Service The Air Conditioning Unit On Cars?
Do I Have To Take My Car To An Air Conditioning Shop To Have It Serviced? One Is Able To Receive Instructions In The Owner'S Manual For Servicing And Maintaining The Coolant System, But They Do Not Include Details On Maintaining Your Air Conditioning Unit. Has Anyone Performed This On Their Own? Tom

You have to be licensed to handle the chemicals used in the system. They can be dangerous not nearly as dangerous as they were years ago. But Still you also have to have special equipment to recharge the system if you were to break the seal. So in short take it to someone who knows what their doing and is licensed to do so.

Water Leaking From Air Conditioning....?
Anyone Can Help Me With This Water Leaking Issue? I Looked At The Problem And Where All Hoses Connect To A Metal Box (I Think It'S Called Duct) Where The Water Leaks From. What Should I Do To Fix This Problem? Thank You.

The water coming from your air conditioner is called condesate- it is the water pulled from the humidity in the air from your home. Check the ductwork again, and look to see if there is a pipe or a hose coming out of it- this shold drain the water either outside or to a floor drain. This line can get blocked up and cause the collector pan inside the air conditioner to overflow.
Usually a good blast of air through this pipe or hose will clear the drain- be careful because once you clear the line all the water will drain out very rapidly.

My Central Air Conditioning System Isn'T Working Properly!?
I Have Central Air Conditioning & Heat. For Some Reason, My Ac Box On The Roof Isn'T Dripping Water Down The Roof Like It Usually Does, And Even Though I Have It Set To 65Degrees, It Is Still 86 Degrees Inside My 2 Bedroom Home. It Was Working Just Fine Last Night! I Don'T Understand! Please Help!! Its A Robert Shaw Ac Wall Remote. That'S What It Says On The Front. It Is Battery Operated Remote Thingy And We Changed The Batteries. As Well As Re Cleaned The Air Filter For The 2Nd Time Since The 1St Of July... Any And All Help Will Be Greatly Appreciated! ~ Many Thanks!

check both of your breakers is about all that you can really do on your own. There should be one for the indoor a/c and one for the outside a/c. Even if you knew that the a/c on the roof isnt running, without a little experience with electrical- stay away. If you can see the iside a/c coil fins next to the filter to make sure it's not frozen. If it is and you call a tech then there isnt much they can do until it thaws. If you own your home then you will pay for two service calls.
