HVAC Services: Heating, Ventilation, and Cooling

Heating, ventilation, and cooling systems are an all in one solution to any of your climate control needs. HVAC systems are controlled by a thermostat which regulates the temperature of the air in your home to keep it cool in the summer months and warm in the winter months. At Air Conditioning Services, we will work with you to design the best HVAC system for your needs.



Having an efficient air conditioning system is a must with the hot summers and the warm days all year in Killeen and Bell County Texas. If you are using a window-mounted AC unit, you can end up spending an exorbitant amount to cool your home. We offer air conditioning replacement and installation solutions that will keep your indoor temperature low, while also keeping your monthly cooling bills low.

Central Air

Central air conditioning units use a single fan and coil system to cool an entire building. There are a wide variety of central air conditioning units available that will fit the needs of any sized building from large warehouses to small cottages and medium sized homes. Fan and coil air conditioning units use pressurized refrigerant to absorb heat from the air inside a building. The system then recirculates the cold air through a duct system that is calibrated to disperse the air evenly through your home.

Ductless Mini Splits

Ductless mini splits are a solution for homes and buildings that do not have the room to install ducting for a central air system. Air ducts will take up space either above your home in the attic or below your home in the crawl space. Mini splits are a great solution for hotels, hospitals, and homes that want individual climate control on a room to room basis.



We strongly urge homes that are using plug-in wall outlet heaters to make the switch to a conventional gas furnace or an electric heat pump. The extra safety that comes with an integrated heating unit is well worth the investment. Wall outlet heaters can cause fires, third degree burns, and are inefficient for heating rooms.

Heat Pumps

Heat pumps are a multi-faceted solution to heating and cooling smaller to medium sized buildings. A heat pump uses pressurized coolant to cool air in the summer and warm air in the winter. Heat pumps run solely off of electricity and are ideal for homes in warmer climates like we get here in Texas.

Gas Furnace

Gas furnaces are a more efficient solution to heating air than a heat pump but use gasses like natural gas and propane. A gas furnace is better for larger buildings that need to heat air at a higher rate, and also extremely efficient for smaller homes. A furnace will integrate into existing AC ducting and can be set to be on the same thermostat.

If your HVAC unit is making a strange noise, has a strange smell, is constantly cycling on, or doesn’t seem to be heating or cooling each room equally, we offer expert HVAC inspection services that will pinpoint the issue.

Air Balancing

If your HVAC system is not cycling air evenly throughout your building there may be an issue with the calibration. During an air balance test, we will determine what areas in your home or building are not seeing the performance necessary and will adjust the fan settings to evenly distribute air. Over time, and seasons of heavy use, your HVAC unit will wear down and may develop issues blowing air through your home, but our air balancing services will get you back to optimum efficiency.

Performance Test

A system performance test is conducted in cases where your HVAC system is cycling on frequently or seems to not be heating or cooling correctly. During a system performance test, we will check refrigerant levels, wear on the belt, fan and motor, and other factors which can degrade the performance of your HVAC system.

Air Duct Leak Test

Older HVAC systems can develop air duct leaks over time that can cause a loss in heating and cooling efficiency. An air duct leak test will determine if there is any air blowing outside of the output vents and if there is any interruption in the flow of air. Ducts can break or crack over time or can be harmed by other improvement projects.


HVAC units are a large investment and that is why it is important to use a reputable company for your services.
