How often should I change my furnace filter?
Regular filter replacement ensures that your system operates at peak efficiency, allowing occupants to
enjoy clean,circulating air that is free of dust, dirt and allergens. If your filter is not disposable, it should
be carefully cleaned every one to two months. Cheap disposable filters should be changed every one to
two months, and premium filters should be changed every two to four months. As a helpful reminder,
mark all required filter changes on your calendar.
How do I know what size HVAC system to purchase?
There is no cut-and-dried answer to this question. It depends upon your home’s age, square footage,
construction type, and insulation type, as well as the performance rating of the system you choose.
Delta T’s indoor comfort experts will evaluate your cooling and heating needs and conduct a whole-
house energy analysis to determine which system will improve your comfort for years to come.
What is an ENERGY STAR® rating?
You may have noticed the ENERGY STAR symbol on many of your appliances, including your furnace
and AC unit. HVAC systems that have the ENERGY STAR symbol meet stringent energy efficiency
guidelines set forth by the Environmental Protection Agency and the Department of Energy, and are
designed to be more eco-friendly than comparable products. Many ENERGY STAR-rated products may
also qualify for tax rebates and incentives.
Why should I care about indoor air quality?
According to the Environmental Protection Agency (EPA), indoor air may be two to five times – and
up to 100 times – more polluted than outdoor air. Newer homes may suffer from high levels of indoor air
pollution because they are tightly sealed and insulated. While this helps with heating and cooling costs,
it does not allow your home to “breathe,” so it traps contaminants inside. Children, elderly residents and
people suffering from allergies and asthma may be at a higher risk for respiratory symptoms when indoor
air quality is poor.
