2 Types Of HVAC Ventilators And How They Can Help Improve Your Home's Comfort

The ventilator in your HVAC unit is the part that ensures your circulating stale indoor air is replaced with fresh, filtered and temperature changed outdoor air. There are different types of ventilators and each has its own pros and cons that can help determine how well-suited the ventilator is for your heating and cooling needs.

What are the types of HVAC ventilators and how can they help improve your home's comfort? Here are some factors to discuss with your air conditioning and heating services company.

Energy Recovery Ventilator

An Energy Recovery Ventilator (ERV) utilizes the heat and humidity in the ambient air to help power the cooling process. The ERV therefore dehumidifies the air so your home will have fresh, relatively dry air to cool you during the warmer months. You will save money due to the increased cooling efficiency and not having to install a separate dehumidification unit.

The downside is that an ERV unit only works to its best abilities if you live in an area that has hot summers but temperate winters. Freezing winters don't provide the ERV with enough ambient moisture or warmth to properly power the furnace and heating process. The unit could still work and provide heat, but you will lose a great deal of efficiency and drive up heating costs by going this route.

Not sure whether the temperature in your area matches up with the ERV needs? Ask your heating and air conditioning installation service for a customized consultation.

Heat Recovery Ventilator

Heat recovery ventilators (HRV) operate in the reverse direction as an ERV. Instead of taking heat and moisture from the outdoor air coming inside, the HRV takes the heat out of the circulating air inside your home in order to heat the incoming fresh air. This makes the HRV a much better choice during a long, cold winter.

But an HRV unit isn't as good at managing a long, hot summer as the ERV. The right choice will again come down to the climate in your region. While both types of ventilators work best in certain seasons and temperature regions, neither will leave you completely without cooling or heating but will simply become less efficient.

If you are on the market for a new central HVAC unit, it is best to meet up with a heating and air conditioning services company to find out the best bet for your region and particular needs. The company can provide you with some specific details regarding the average efficiency of each type of unit when installed in your area.
