We are taking the following precautions due to the COVID-19 virus. All of our technicians have masks, glasses, latex gloves and shoe booties if they have to enter your home. Our technicians also have hand sanitizer and disinfectants that they use after every call.
If we are there to do maintenance and we don’t have to come inside your home to get to the equipment, we are asking homeowners to adjust the thermostat for us so we can do the system maintenance without entering the home. We will not be shaking hands and will keep our distance from customers.
There are several types of air filters available to install in your HVAC system. The industry standard for measuring the effectiveness of various air filters is called the Minimum Efficiency Reporting Value or MERV rating. MERV ratings run from 1-16 with the higher number filters able to trap smaller air particles.
Here are the types of air filters available to homeowners:
Fiberglass air filters – The fiberglass filter employs a simple box-like construction and flat panel design. The low MERV rating of 1-4 indicates this filter will only capture large particles. The HVAC system in your home will be protected, but smaller particles will be able to enter your home’s indoor air circulation reducing air quality.
Pleated or polyester air filters – A high MERV rating of 6-12 is assigned to the pleated filter because of superior particle-trapping ability. The pleated design allows for a large surface that captures small and large particles. Carbon-infused pleated filters remove odors and anti-microbial infused filters remove allergens.
Washable filters – Regular maintenance is needed for washable filters to maintain efficiency. Installing the filter when it’s still wet can cause fungus to collect on the filter material. Keeping a second filter ready to switch will allow time for the cleaned filter to dry. The MERV rating is a low 1-4.
High-efficiency air filters – Dense filter material arranged in a pleated design enables this filter to trap very small airborne particles. The MERV rating is a very high 13-16. The dense construction can impede airflow reducing efficiency. High-Efficiency air filters are used by homeowners with special air quality concerns.
