Gary and Sons Inc opened for business in 1978 as Gary's Dehydrator and Stoves. Soon their reputation as wood and coal stove specialists led them into the wood and coal central heating business. As their experience continued to increase, Gary and Sons Inc. quickly became a leading heating and cooling installation specialist, encompassing all fuel types. Today the heating and cooling business is still the keystone of Gary and Sons Inc. but Gary and Sons continued dedication to their customers needs has given birth to a wide range of new products and services such as, annual maintenance agreements and 24 hour emergency service, zero clearance gas and wood fireplaces, Keystoker automatic fed Anthracite coal stoves, furnaces and boilers, as well as vented and vent free gas logs.

ADDTL ADDRESS: PO BOX 39, CHAMBERSBURG, PA 17201.

"THE WORST COMPANY I have ever delt with. The repair lasted for 17 days and then they refused to come out and fix the problem on a system they had installed that would have still been under warranty if I was the original owner. I told them I wasn't going to pay so the charged an old credit card on file. STAY AWAY FROM THIS COMPANY !!!"

"We had Abma come out to fix our AC unit this summer. They charged us over $400 to get it running. A week later the unit stopped working again. They came back out to look at it and said the unit needed to be replaced. Now, four months later, we get a $90 bill for the second visit. After talking to them, there was no compromise on the second charge. Horrible customer service."

Heating and Air Conditioning questions, answered by experts

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).
