Having problems with your Air Conditioners ?

Answers :

In some models the air conditioning system and the heating system are separate and you need to switch off the aircon if you use the heater. Or if it is a heatpump system, the fan will switch off while it is in reverse cycle allowing pressure to build up and heat to be generated in the evaporator side. This is particularly true if you change directly from cooling to heating.

I have a heil -- model NUGK100DH12-- problem is when power is supplied to it the blower fan comes on right away along with the induction blower and it does have the electronic pilot which all works to thermostat setting. when setting is reached the flame shuts down normally and I think the induction motor cycles correctly, but the blower motor never cycles off. It's on constantly. I tried replacing the fan relay to no avail and am considering replacing the timed fan controller as the next move

I've had to replace the blower motor on an old GE electric furnace three times in the past year. The first time the motor just stopped working. So I replaced it with an A.O. Smith motor for the summer. It worked just fine during the summer. Winter comes along, switch the thermostat to heat and the house fills up with light smoke with a smell of burning plastic. I replace it again with the same brand and model # along with a new capacitor. It ran fine for about an hour or two, then it began to bl

Can I switch my blower speed on my carrier 9300ts to high? The airflow out of my registers is extremely low. I didn't know if gas heat - high had anything to do with the blower motor speed or not. I got a wood burner that has cooper coils in the plenum and I was thinking that increasing my blower speed will help dissiminate the heat faster. It takes about an hour of time to change my temp by 1 degree. Any assistance would be helpful

We had our furnace replace this winter, our air was only about 8 years old and working fine so we didnt change it, well now , the air coming out of the vents are cold, but the condenser NEVER shuts off and the thermostat never reads what it is set on, it stays 2 or more degrees higher, the company that installed the furnace checked the air and said everything is working fine, and leaves me high and dry and HOT... the freon level is good, the pressure reading is good, but the house is hot and the


Hi, if the new furnace they put in did not have the right size coil to match the outdoor unit, it would run all of the time and not cycle off. Lets say if it is a 3 ton condenser, the indoor coil must be a 3 ton coil as well. If they put a 2 !/2 coil ... Air Conditioners

Have just fitted a replacement Honeywell powerhead for Honeywell V4073A 3 -way valve at my daughter's house.

After fitting all seems to work correctly except the motor casing inside the powerhead is very hot to the touch, even when the system has been shut down for some time.

I have two duo therm Ac units on my houseboat.

I have an old RUUD central AC unit that started blowing hot air. I set the thermostat to off and set the temp gage higher than air temp to turn the unit off and save money, but inside blower unit runs constantly. I'm trying to save money to have it serviced, but noticed my electric bill was higher that last month when the ac was working. The bill was about 4 times higher than the winter when ac is off and the gas heat kicks in. Can the blower running constantly cause this power usage and what is

The outside compressor and fan will not shut off. I have turned the thermostat system to Off and even to heat, but it will not stop.
