The HVAC industry changes for 2018 will have the most impact on homeowners who have older heat pumps and air conditioners, and the amount of fresh air ventilation new homes require. The phasing out of R-22 is nearly complete as the 2020 deadline approaches and the building codes for ventilation have been relaxed.
Refrigerant Phase-Out
If your central HVAC system uses R-22 and needs refrigerant, you’ll have to pay higher prices to fill it. Since 2010, no new systems can use R-22 because it’s an environmental hazard and the amount produced each year has been diminishing. By 2020, production will cease altogether.The new rules governing R-22 apply to HVAC technicians who need to handle it. They must pass a certification exam, and keep the certificate for three years after it expires. The technicians must also record how much they remove from a system that uses R-22, and how they disposed of it. They must also record where they disposed of the HVAC equipment.
Ventilation Codes
The International Residential Code (IRC) makes periodic changes to their building codes. They’ve rolled back their fresh air ventilation requirements to the levels established in 2010. Ventilation helps keep air healthier indoors either by exhausting stale air and replenishing it with fresh.Newer homes have been built to higher energy efficiency standards and require more mechanical ventilation since they have few air leaks caused by cracks or gaps in the exterior envelope.Some builders include balanced ventilation systems, like heat recovery ventilators (HRVs) that pull out as much interior air as they pull in from the outdoors. If not included as a standard feature, your HVAC contractor can add an HRV, which is the most energy efficient way to supply fresh air year-round.
