The air flow you feel coming out of the vents is good on heat but not when the ac is running?

Turned to the air cool setting for the season. worked at first then got intermittent flashing '61' and 'CH'. unit will not respond by remote or on the case


Condenser coil over 65°C. Check coil and filters are clean and free from debris, and airflow is OK. Check system pressures for non-condensables

KNOWING ABOUT CONDENSER


What is a condenser?
Is a device or unit used to condense vapor into liquid. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser.
Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low.
A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat.
In a heat pump unit the condenser has a few more features. It will have a reverse valve that allows the unit to switch back and forth between air conditioning and heating. Even when the unit is heating, it uses the condenser for defrosting the coils. If the coils become layered with frost it will effect the units effectiveness this is defrosted when the reverse valve switches to air conditioning mode to move the hot gases through the coils melting the built up ice. It will automatically switch back to heating mode once the ice is cleared to once again heat the home.
To keep your unit in good operating condition it is vital to keep the area around the condenser clear of all debris as well as keeping the filter clear of dust and dirt. A clean machine makes a happy machine. A happy machine will keep you cool during the summer months and warm during the cold months. It is suggested to change the units filters when they become dirty, depending on your area and conditions near your home this may be as often as once a month or as seldom as every 3 to 6 months. You will have to pay close attention to your units needs to decide the right time to change or clean your unit’s filters.
It is very important no matter what type of unit you have to prevent the blockage of the condenser. If the condenser becomes block it can effect the units efficiency or even cause the until to completely fail. For this reason it is one of the most important components of a cooling or heating system. A condenser allows the maximum airflow to the unit.
Keeping you condenser in good running condition will not only prolong the life of your heat or cooling system but also provide you with the most efficient heat and cooling system saving you money on heat and cooling.www.victorwod1234.blogspot.com

The furnace is leaking water when the air conditioning is on... rheem 90plus edition


Hi,
It sounds like the condensate drain or the 3/4" pipe that comes out of the bottom of the coil is plugged...then the water runs all over...

2 Rheem Protech 500 thermostats, 1 upstair & 1 downstairs with a Rudd Achiever 90Plus gas furnace. Thermostat downstairs works fine but upstairs one cycles fan on and off 2-3 times during heating...


Have you checked to make sure that all of the supply registers are open, the air filter is clean and nothing is blocking the return air grill?
It almost sounds like you could be cycling on a limit switch.
Usually on gas furnaces, the blower is controled by the onboard controls, in the cooling mode the thermostat will control the blower.
I would be looking past the thermostat, at the furnace it self.
I hope you find this helpful. If you continue to experience problems, please let us know and we will dig deeper. :)

Heat pump and gas furnace running at the same time.


An explanation....

When in the heating mode, all heat pumps are dependent upon the outdoor conditions to remove heat energy from the environment and turn it into useful heat for your dwelling.

Heat pumps operate more effectively in temperate climates (as in southern states) and if it's as cold as you say, then the furnace is coming on to add auxiliary heat to the space to make up for the lack of heat being supplied by the heat pump. This is normal.

Some heat pump systems are or can be equipped with a control known as a "low ambient cut out" and/or "motor master" that prevents the heat pump compressor from operating and slows or stops the condensing unit fan when it's too cold and risking potential compressor damage. When it's in the single digits outside, a heat pump is only marginally effective. and usually requires auxiliary heat (your furnace).

If the furnace keeps operating when it's in the 30s or 40s, you may want to have the system examined by a competent service technician. As always, the outdoor condensing unit should be kept clean and the furnace filter should be changed no less than monthly, unless you have an electronic air filter.

Extremely long time to get cool air with 5 ton 13 seer goodman heat pump which is 3 years old.


Check your filter. Make sure it is clean. Make sure the outdoor unit is operational. (power on). Clean your condenser coil with a garden hose. If possible check your evaporator coil. If it is dirty clean it. Your furnace (or air handler) blower speed should be set on high. All of your registers (supply & return) should be open and unobstructed. Check for proper thermostat settings. If none of this information solves your problem , then your units charge needs to be checked. You could be over or undercharged with freon.
Good luck......

Ruud heater will not light consistently


Your furnace is going into a lockout condition, cycling the power resets the circuit board and it starts over. I will need to know approximate age and model of your furnace, it sounds like you have need to clean the flame sensor rod. However i need to know what i am working with.

Furnace is leaking water


This is not a lot to go on.

I assume since you called it a furnace, you have hot air heat and central air conditioning. If so, the only way a furnace/AC unit can generate water is by condensing moisture from the air. This is common to all air conditioning and removes humidity from your home. If so, this water, called condensate, must drain. The condensate is collected at the AC cooling coil that is typically located on top of a vertical upflow furnace or downstream of a horizontal furnace. If the drain is clogged, it will overflow and create a mess in and around the furnace. If this is your problem, cleaning and clearing debris may solve the issue. I suggest starting with the easiest accessable part of the drain path. You may need to open the panels enclosing the AC coil and clean the small pans at the bottom of the coil and clear openings from above that look similar to a laundry tub drain. If you get that far and find rust holes in the pan, repairs are needed. If you have an electric condensate pump that may also be the cuprit and require cleaning. Check and clear all drain lines from the coil connection to the final dicharge - sump pit or outside.
