Because of this miscalculation, it may be possible to determine a lower cooling load thus causing you to need less tonnage for your situation. If you keep the old system, it will eventually suffer from inefficiency and excessive use which will lead to a decreased lifespan. Switching to a reduced cooling or heating load unit will cost less money and require less maintenance visits in the future.
When considering an upgrade, keep in mind that recent developments in HVAC have included the use of “smart” technologies that function using wifi, cell phones, laptops, and tablets. Because of this, your entire home can be managed from a distance. Many of these “smart” technologies will also be able to lower your energy expenditure as they precisely monitor all areas of the home and adjust demand to match necessity. Older HVAC units do not have this feature and will use more energy, over time.
The most popular device currently being installed with a new or old system is a programmable, smart thermostat. This device can combine local weather forecasts within its algorithm and adjust your homes atmosphere accordingly. It can also record and respond to various settings to accommodate all those who live in the home. The ease of control and remote commands make this upgrade feature a must have for energy efficiency.
