In a hydronic system for heating you must insure that the pressure on the boiler is maintained during the process of bleeding off the air from the system. There is a regulator for the water make-up to the system which normally maintains 12 PSI with the boiler cold. If this is stuck or fails to open you will loose the pressure on the system when bleeding the air off. Most are adjustable. Loosen lock nut on the adjustment stem and turn the screw (clockwise) to increase the pressure. Count the turns as you adjust it and return it to the original setting when you finsh bleeding off the air.

I have Whirlpool window unit ACM082PR2. Water is draining into the house. The unit is level. I don't what to do to get to stop draining in the house. Bruce Hansen


Hello, you want the unit tilted back in the window somewhat, the unit should not be level because this will cause the wateR to settle in the front of the unit and drip. Also, if the unit has a drain plug remove it so the water can drain out of the unit.

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

The boiler wont fire up and the blue light flashes once per second


Let's see what we can do to trouble-shoot this boiler--

First of all-- Are we talking about a Hot Water 'Boiler'-- In other words does this boiler heat water that circulates thru the house, to keep you warm?

Next-- What is your fuel?

Have you Shut the system down, to reset it?-- What happens when it comes back on again?-- Clicking sounds-- pumps trying to start-- solenoids trying to open, etc.-- Tell us what you observe-- so we can help you trouble shoot this problem.

I have a split system SAP-K181AHA, SAP-K241AHA that is leaking water from unit inside house.


Air conditioners wring moisture from the surrounding air that collects in a pan under the cooling coil in the inside unit.

Chances are that the condensate drain is plugged or the drain pan is plugged. Look for a hose that exits the inside unit and runs to a drain. You can follow it back to the drain pan of the A/C unit. If there is water sitting in the pan, then either the hose or pan or both are plugged.

Turn the unit off, get a small bucket and remove the drain tube. Catch the water in the bucket. Blow through the drain line until it's clear. If the thought of doing this is too repulsive, then use an air compressor or even a manual tire pump. Now check the drain pan in the unit for debris and remove as much as possible from the pan and the drain fitting.

Both the pan and drain line should be checked at the beginning of each cooling season.

Reinstall the drain tube and see how it works!

Where is the drain pan on my central a/c/? It drains inside my air vents.


most central a/c units have a drain that either goes into the house drain system or they have a pump with a float activated switch to pump water out once full. to identify you must find your air handler ( the unit that blows air into the house) remove the lower panel and look for one of the foremantioned drain systems. could be a simple mold problem, mold tends to build in the drain tubes because the flow of water is relatively low.

Thermo Compact Vaillant Boiler


the thermocompact is a non-condensing model, and should be o.k to fix, you do not need a cylinder as is a combi model and would provide hot water on demand!

I have a Baxi Combi boiler and want to add new TRVs to the radiators. Do I need to drain the system or can just turn off all the radiators and hope not much water escapes. How do I add new inhibitor...


You will need to isolate the boiler from the radiators because there is an auto feed valve that will continue to allow water into the system if the pressure in the boiler drops. There should be some valves off of the boiler that will allow you to do this.

I have a 48 year old Bryant Boiler in my home for our heating system. I need to bleed the boiler as there are not any places to bleed the radiators. How do I bleed the boiler


why do you need to bleed the boiler. this just means drain it. if it is air locked at the rads you need to get rid of the air

Air conditioner leaking


Hi, There are no pipes, just passage ways on a window unit. It probably needs cleaned. Window units naturally create water in the evaporator area. The water is suppose to drain to the back of the unit through passage ways to the condensing area where the slinger ring on the condenser fan blade slings it into the condenser coil making it more efficient. There is usually a drain hole to drain excess water from the back of the unit. Any dirt or algae in the pathway of this water or the wrong tilt will cause water to build up and drip or blow out the front. Anything touching the evaporator coil allowing water to run down the obstacle into the wrong area will cause the same thing. reduced air flow will cause the evap to freeze which could also cause a water problem. Since the tilt is right and it doesn't seem to be freezing, Maybe a temporary increase in tilt and a dropper of bleach at the base of the evaporator would do it. This will kill the algae and may unblock the water flow. NOTE: It may also cause stains on a carpet or floor if the bleach water drips onto it. If you want to pull it out and clean it, most units can be pulled out of the housing and sprayed with a water hose but you need to be careful not to get water in the electrical parts of the unit. They can be covered with plastic or foil. Make sure you unplug the unit before trying to remove it. You may have to remove some screws to remove it from the housing. Hope this has helped. kstfas
