Have You Been Switching Back and Forth From Heat to AC?

Many homeowners find it difficult to regulate the temperature in their homes during the Fall. You switching back & forth probably woke up this morning with a nip in the air, but temperatures are supposed to warm up  this afternoon.

During the day air conditioner may need to run, but find it may be too cool for sleeping. Many people switch back and forth between the heating and air conditioning system when spring brings warm days and cool nights.

But will this damage your HVAC system? Generally, switching back and forth between heating and air conditioning modes won't cause any problems.

However, sometimes switching back and forth can cause your system to shut off. If you "short-cycle" the air conditioner, it can cause the fuse or circuit breaker to trip for the outdoor condensing unit.

This is a mistake many people make. When the unit is in the cooling mode and the thermostat is calling for cooling, the outdoor unit is on. If you adjust your set point temperature higher to shut it off and then immediately dial the setpoint temperature lower it would call for cooling again and cause the compressor to lock-up.

The reverse is also true. Should the cooling unit finish a cycle and shut down and you immediately go to the thermostat and set it lower, the equipment will attempt to come back on but the compressor will probably lock-up because  the pressure has not equalized in the system.

When a compressor locks up during high pressure start-up conditions, it will draw a very high amp rate.This can cause a breaker or fuse to blow. Some units have built-in "Anti Short-Cycle" timers. Some digital thermostats have built-in time delays to prevent this from happening.

If your system shuts off, first try checking the fuses or breakers. You should also check the outdoor disconnect for your unit. Some have a separate breaker.

You should get in the habit of letting your thermostat set in the OFF position for at least 5 minutes after it shuts down, before starting another cycle. This allows the refrigerant pressure in the system to equalize.

Should your system shut down and you have checked the breakers or your fuses and that isn't the issue, you should then call a repairman. The problem may be more complex. 

We recommend regular HVAC maintenance to help prolong the life of your equipment. Our Fall Furnace tune up can prevent minor issues from becoming major ones. Should you need a new air conditioner or furnace, Ohio Heating & Air Conditioning is here to help you decide which system will work best for you and your budget.

Choosing the Best Size for Your New AC is Essential

Posted by Ohio Heating

May 11, 2021 3:05:00 PM

Is it time to upgrade your old AC? When considering new equipment to cool your home, you need to choose a unit that is the right size. Is bigger better? How important is size? 

Correctly sizing your new air conditioner is critical in improving the comfort of your home.   woman confused_s

Many people assume that the bigger the unit the cooler their home will be. This isn't true. If an air conditioner that is too large is installed, you could have a problem. Oversized equipment is actually less effective and also wastes energy and money.

Air conditioners remove heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

When the air passes over the evaporator coil which is very cold, the temperature drops about 20 degrees. In Columbus and Central Ohio, where we have high relative humidity levels, the evaporator coil doesn't just cool the air but also acts as a dehumidifier. This happens when the air hits the coil and the temperature of the coil is below the dew point of the air.

This causes water vapor to condense on the coil. With a cooling unit that is too large, water vapor condenses on the coil but you don't get enough condensation on it for the water to start dripping down into the pan below the coil. If this happens the water isn't drained to the outside. Then your home has a damp clammy feeling.

An AC that is too big can also be more expensive to buy and to operate. It will start and stop more often, thus shortening the lifespan of the equipment.

When a cooling system is over sized, it starts up and shuts down a lot more because it runs for only a short time to meet the thermostat set point. All those starts and stops mean you'll probably be repairing it more often and replacing it sooner.

Buying the correct size equipment for your home will not only save you money on the initial purchase, but also on save you money on energy costs and equipment repairs. Deciding what size is right for your home can be difficult, but the experienced team at Ohio Heating & Air Conditioning can help you find the system that is perfect for your home.
