Lots of homeowners prefer central HVAC system installation for interior temperature regulation. The problem is that HVAC systems are large and contain numerous fragile components that are easily damaged. Central air conditioning and heating networks also need regular expert maintenance to operate at peak efficiency. To glean some great helpful hints about maximizing central HVAC system life and performance, read on.

Many people panic if their find their central AC unit icing up. Frozen drainage lines are often mistaken for leaking pipes. While turning on the fan by itself may thaw the system out, seek professional assistance in the meantime.

In the springtime, wipe down the coil and condenser fan blades. Again, be sure to switch the power off before you begin working. Then, detach the grill and gently clean interior blades. Next, wipe down the unit itself.

Many HVAC condenser fans have oiled components. If this is the case, you should apply lubrication applied no less often than annually. Such parts are typically covered with metal or rubber, so use an SAE-20 oil that is lightweight and non-detergent. Spread about 10 drops of oil into each port but do not overfill the openings.

Place exterior central AC compressors in a shady area. That way, it doesn’t have to work as hard to cool because incoming air will already be slightly cooler. In the long run, it will use less energy as well.

Enhance HVAC system energy efficiency by installing a radiant attic barrier to obstruct hot airflow from the outside. This will further reduce the amount of energy required to cool your home and might even free up extra storage space in your attic.

Keep protective covering over your HVAC condensing unit throughout the cold winter season. The extra layer of material extends the life expectancy by reducing exposure to extreme temperatures. Another wise precaution is never using the compressor whenever the weather drops below 60 degrees. Instead, use the fan only to prevent excessive HVAC system stress.

Be sure to actually check any references that a professional HVAC contractor provides. Prospective customers often assume that all references will be positive, but that doesn’t always prove correct, however. Taking just a little time to verify references is very worthwhile.

Ensure that heat loss is included in any HVAC contractor’s calculations. That value is essential to determine HVAC system BTU rating accurately. A standard part of calculating heat loss correctly is counting windows and doors, as well as interior living area and an insulation check.

Quite obviously, there are several basic things you can do to help prevent your AC unit icing up and choose a reliable HVAC contractor. Proper installation and routine maintenance both play essential roles in prolonged central air conditioning and heating system useful life span and operating efficiency.
