Correct installation techniques can bring an air conditioner’s power consumption to a new minimum.
In order to achieve the best results out of a highly efficient cooling system, constructors and HVAC specialists need to first make sure they are using effective building blueprints and installation methods. Here are the top practices that all builders and their respective contractors must follow to offer the best energy savings to their householders:
Begin with a hermetic building envelope.
A house functions like a system, so the first stage in bettering the performance of a cooling appliance would be to air seal and isolate as best as you can. Some very effective methods to reduce air leakage and make sure that cool air remains where it’s supposed to is to use high quality windows, cutting-edge framing techniques, as well as perpetual air barriers.
Size equipment and ductwork accurately, in concordance with the ACCA (Air Conditioning Contractors of America) standards.
A precise calculus of the home’s cooling output is vital in determining system’s effectiveness and the level of thermal control inside the room. An ac installation that is too big will not properly eliminate humidity, while on the other hand an ac installation too small would not be able to achieve a desirable temperature during the warmest days. Most HVAC specialists use ACCA’s Manual J mathematical formula to appreciate the optimal system size based on a variety of factors such as the isolation degree, window placing, regional climate, and so on. We’re long past the days when sizing an air conditioning unit was based on the number of square feet or other guidelines.
Put emphasis on ductwork layout.
When it comes down to the air conditioner’s efficiency, there are not few those who believe that ductwork layout is probably just as significant as equipment picking. Keep the length of the duct runs at a minimum and set ductwork in conditioned places as much as you can (but avoid lofts). Also, make sure to insulate ductwork in unconditioned places such as the basement.
Don’t forget to seal the ducts.
Studies show that roughly 20% of the air traveling through the duct structure is wasted because of gaps, leaks, and loose jointing. Verify if contractors seal the ducts accordingly, particularly around connections to air intakes and registers through which air could infiltrate into walls and cause moisture issues.
Design suitable supply and return vents.
Cooperate with contractors to ensure there is a sufficient amount of air supply registers to bring in the cold air and enough return vents to transport heated house air back to the ac installation.
Choose condenser’s and air handler’s location carefully.
Install the condensing unit somewhere outside where no close objects could block the flow of air. Place the air-handler in a centralized position indoors to reduce duct runs and to allow for more effective access for precautious ac maintenance. As soon as they are installed, check if the equipment has the right refrigerating charge and airflow rhythm as attested by the manufacturer. A poor refrigerant charge may lead to several issues ranging from low efficiency to more severe system malfunctioning that affects the air conditioners as well as the heat pumps. Analyze the airflow in every single room to ensure that everything is working correctly and that the ambient in each room is comfortable.
