Modernize an old system · 2.Invest in a completely new system · 3.Increase the insulation of your space · 4.Doing something as simple as properly sealing heating and cooling ducts can improve air conditioning efficiency by 20% or more. Finding an HVAC technician with experience sealing ducts is the best way to maximize additional efficiency. The Department of Energy recommends keeping the temperature at 68 degrees Fahrenheit in winter and 78 degrees Fahrenheit in summer. When you're not at home, you can lower or increase the temperature to keep your HVAC system running at a minimum.
Adjusting your thermostat between 10 and 15 degrees for eight straight hours during the heating season can save you 5% to 15% on your heating bills each year. Programmable thermostats automatically lower or raise the thermometer according to a set schedule. Initially, you'll enter your preferences at pre-set times. Some programmable thermostats have a 7-day programming option that allows you to customize the settings for each day, while others have a program for 52 days, 5 to 11 days, or 1 week.
While you're checking for gaps between the studs and the drywall in the walls and attic, it's also a good time to inspect the insulation for spots where hot or cold air can escape. The EPA estimates that you could save about 15% on your heating and cooling costs by simply sealing air currents and adding insulation to your home. Add insulation in the attic, on the floors above a mezzanine and around the joists on the edges of the basement. Window covers can significantly affect your home's heating or cooling load.
Energy Saver claims that it can reduce heat gains by up to 33% and reduce heat loss by 10% simply by installing curtains. To get the most out of any HVAC repair, upgrade, or replacement, work with a qualified HVAC contractor. When in doubt, contact a nearby HVAC professional for recommendations and an explanation of HVAC energy efficiency ratings. Taking a proactive approach to a building's HVAC systems through regular quality maintenance can reduce commercial HVAC maintenance costs by up to 40%.
If your HVAC unit is less than 10 years old, but works as if it needed an upgrade, you may be able to perform some simple repairs instead of a complete system overhaul. Another way to significantly improve the efficiency of your heating, ventilation and air conditioning system with minimal labor is to replace doors with energy-efficient doors and repair or replace any old weather strip. Dirty filters overload HVAC systems by restricting airflow, cost much more to use, cause poor indoor air quality, and cause many more problems and maintenance costs than commercial HVAC systems. For more information on how to find and work with an HVAC contractor, see the PG%26E e-book The Complete Guide to Working with a Lighting or HVAC Contractor.
Sometimes, the best way to improve the efficiency of heating, air conditioning and air conditioning is to upgrade or replace existing HVAC equipment and systems.
