What is the best thermostat setting for my air conditioning?

Setting your thermostat at the perfect temperature is an integral part of efficient air conditioning systems. The best thermostat setting for your specific air conditioning system is the temperature that you need to remain cool and comfortable throughout the summer. The thing you need to remember, however, is consistency. No matter how strong and efficient your system may be, adjusting the temperature of your home is not automatic! The more you keep trying to adjust your thermostat, however, the more your system will work, and the more money you will spend in the long run. Set your thermostat at the temperature you deem appropriate and then leave it either on “Hold” or “Automatic”. Consistency is a key component in efficient air conditioning systems.

How often should I have my air conditioning system checked or maintained?

Routine maintenance is the key to the longevity of your system, however we understand that you may not be able to have constant maintenance on your system. At the very least you should have your system checked at the beginning of every cooling and heating season. Your system is always at its most vulnerable every spring and fall. The moment you decide to switch your system from “Heat” to “Cool” is the moment you should call ACA Mechanical to make sure that your system is running at optimum efficiency.

How often should I change out the filter?

Experts all try to give you a magic number as to when to change out filters, the truth is, though, that there is no magic number. If circumstances allow, routinely check your filter, and the truth is that you will be able to tell if the filter needs replacing. We believe that you should change out your filter every 6-8 weeks during the milder seasons and change out your filter at least every 4 weeks during the heavy summer seasons.

How often should I add Freon to my system?

If your sir conditioning system is installed correctly, adding Freon should not be necessary. If you find yourself needing to have technicians constantly add Freon to your system, even if it is only once a year, that is a sign of leakage within the system. Refrigerants are not supposed to enter our atmosphere and if you have a leak within your system you should call ACA Mechanical immediately so that we can properly seal off your system.

Should there be ice on the air conditioning unit refrigerant line?

No. You should never have ice forming anywhere on your unit or refrigerant line. If you do experience ice anywhere on your unit this is an indication of an improperly charged system. The most common causes of this can be that you may have a low refrigerant charge or there may be a possible clog somewhere on the refrigerant line itself. If you experience ice anywhere on your system you should call ACA Mechanical immediately. If you have the situation remedied immediately usually only a minor fix is needed, if you wait to long, though, this simple problem could eventually lead to major damage to your system.

What does HSPF stand for?

The efficiency rating for heat pump equipment is rated by the Heating Seasonal Performance Factor, or HSPF. The higher the HSPF rating, the more efficient the unit.

What does AFUE stand for?

The efficiency rating for gas furnaces is rated according to their Annual Fuel Utilization Efficiency, or AFUE. The higher the AFUE rating, the more efficient the unit.

What is the difference between a split system and a package unit?

A split system uses indoor and outdoor components to provide a complete home comfort system. A package unit, however, is different because it does not require external coils, heating units, or air handlers.

My utility bills are high. Will a new system lower my bills?

How long does a typical furnace last?

On average, a furnace can last between 10 and 20 years. The longevity of your system depends on a multitude of factors including routine maintenance, local temperature and atmospheric variations, and personal settings. Sometimes it pays to replace the old system sooner, however, because of two specific reasons. The first reason for replacing your unit, especially if it is over 10 years old, is that modern equipment has much higher efficiency ratings which equals lower utility bills (saving you money in the long run). The second reason is that, especially if your system is over 10 years old, you have no idea when it will finally give out, leaving you with an unexpected major repair to pay for. Most of us are not able to pay for an entire new heating system at any moment. By replacing your old system before it finally gives out, you are able to circumvent dealing with an unexpected repair and you are able to actually plan on and invest in a new,
