Can R-410A be added to top off an R-22 System?

No. Technicians use gauges to determine the pressure/temperature correlation according to the manufacturer; this correlation provides the basis for making refrigerant adjustments.   R-410A is nearly twice the pressure per temperature than R-22.  Combining these two refrigerants, with different pressures, would create a new blend without a known pressure/temp. Correlation and would impair the ability to determine future system condition.  Furthermore, the mineral oil in R-22 will not mix with R-410A.   

New Energy Standards

On January 1, 2015, new efficiency standards went into place.  The new standards require all split AC systems in the southeast and southwest regions to increase from the current 13 Seasonal Energy Efficiency Ratio (“SEER”) to the new 14 SEER minimum. Also, all split system heat pumps must increase to 14 SEER and 8.2 HSPF. 



DO-ALL HEATING & AIR

Proper 

Maintenance


Ninety Percent of all indoor air issues can be traced back to poor system maintenance or neglect. 
Annual maintenance is essential to effect energy efficiency and preserve the lifespan of your HVAC system.


According to Energy Star, HVAC alone accounts for as much as half of the energy used in your home.  HVAC systems can have a big effect on your utility bills — and your comfort.  Energy Star recommends annual tune-ups and proper system maintenance to ensure homeowners are obtaining optimal comfort and managing energy costs.





Modulating HVAC System

Fixed speed HVAC systems operate at a single speed whereas modulating systems have multiple
speeds that allow home-owners the capability to control the temperature throughout the entirety of their home.   Modulating systems permit homeowners to manage
hot and cold spots by managing airflow intensity and duration.  

Because modulating systems cycle more than traditional systems, they remove moisture from the air and reduce humidity. The reduction in humidity permits homeowner to achieve comfortable living temperatures at increased thermostat levels and thereby reduce HVAC energy consumption and cost.  Decreased levels of humidity also reduce the likelihood of mold growth which may be damaging to both human health and the home.
