The Importance of Proper Design

In order to reduce HVAC repair, maintenance, and utility costs, professional contractors engineer every new heating and air conditioning system according to the guidelines published in ACCA Manual J. This ensures that the capacity of the equipment will precisely match your home’s load requirements even in the most severe weather. Manual J accounts for the structural characteristics that affect energy consumption, including windows, doors, perimeter tightness, glass exposure, insulation values, and climate conditions. Contractors that offer equipment recommendations before running a full set of load calculations should be avoided.

HVAC System Options

Homeowners have a variety of choices when selecting heating and cooling equipment. There are a number of systems in different configurations designed to address different structural challenges, performance expectations, and fuel options.

• Split Air Conditioners: In new construction applications, homeowners looking for low noise and high efficiency usually choose to install a split system air conditioner. The air handler or furnace is placed inside the garage, basement or a dedicated mechanical closet. Refrigerant lines and electrical connections are run to the outdoor condensing unit, which is set in a remote location to reduce noise levels.
• Package Units: Package units include a condenser and air handler in a single enclosure. They are designed primarily for rooftop applications when ground space is limited, or the unit might be subject to possible damage. Package units are used extensively in the light commercial market, and they are available in straight cool, gas-electric, and heat pump configurations.
• Heat Pumps: A heat pump operates in the same way as an air conditioner except it includes a reversing valve so the refrigerant can flow in either direction. This allows a heat pump to provide both heating and air conditioning from a single unit. Since heat pumps work by transferring thermal energy, they are most appropriate for areas where the temperature rarely falls into freezing temperatures.
• Furnaces: Furnace models are offered in natural gas, fuel oil, and propane varieties. A natural gas furnace is the most common residential heating appliance. The fuel is usually inexpensive, and the delivery infrastructure is available in most metropolitan areas. Propane furnaces are often used in rural locations where natural gas is unavailable.

The Installation Process

After the new equipment has been selected, the installation phase of the project can begin. At Watkins Mechanical, we always conduct a job site visit to ensure the actual construction conditions are reflected in the mechanical plan. We understand how a construction project can be disruptive to your family’s lifestyle, so our technicians work efficiently and accurately to maintain the installation schedule. When units are set and the final connections are made, the system is always air balanced to ensure the proper amount of conditioned air is delivered to each room in your home.
