Annual Maintenance Checks

Properly serviced equipment will last longer and run more efficiently. In addition to your main appliance, many accessories require annual maintenance. We can perform these checks while the main appliance is being serviced to save you time and money.

Chimney Repair and Modifications

Ensuring proper venting of dangerous combustion byproducts is a primary concern for all HVAC professionals. AABAL Heating & Cooling can ensure combustion byproducts vent properly and do not become a safety hazard.
This may require modifying an existing chimney or utilizing equipment with direct vent capabilities. Not only do we offer chimney repair, we also install new liners.

Have you seen windows open in your building in the middle of winter to regulate the temperature? If you have a multi-unit apartment building with only one heating plant, it can be hard to hold each of your tenant’s accountable for his or her individual energy use. With fuel prices so high, just paying the mortgage, taxes, and gas bill can deplete your monthly budget. The simple solution is individual heat.
Give your tenants the responsibility of paying their own gas bill. Then, if they want to keep their apartment 85° in the dead of winter, it won’t bother their neighbors and your finances won’t suffer. A conversion investment pays for itself within a few years. Simply use the money you save on the gas bill to pay for the conversion.

Repairs and Replacements

Our experienced contractors handle repairs for all makes and models of HVAC equipment.
Eventually, your current equipment will need to be replaced. Ensuring the right size unit is installed is a significant part of the replacement process. The old theory that bigger equipment is better no longer has merit. Modern equipment is designed to run for a set amount of time and then not be used for a period of time.
We perform a load calculation to find the right size equipment, instead of replacing your equipment with a model of the same size. When it comes time to replace, it is wise to purchase energy-efficient equipment. Because energy prices continue to increase, energy-efficient options are the best way to keep your investment cost-effective in the long run.


Even with regular maintenance, equipment can still fail or fall short. Our basic service charge covers any minor problems. If new parts or major repairs are required, the service charge goes toward the repair work directly.
