Mechanical air filters trap pollutants by filtering them out of the air as it passes through. Electronic air cleaners pull air in, give the pollutants in that air a static charge, and trap those pollutants on an oppositely charged surface. By working with a qualified professional you can rest assured that you have the right air filtration system in Seattle, WA.

I had these guys out yesterday to do my routine furnace maintenance. They were right on time and very helpful explaining how my furnace worked and how the internal filter can be cleaned. They were extremely knowledgeable and helpful discussing different options for filters with families who have bad allergies. I will definitely hire them for all of my furnace needs in the future!
Put simply, any home that uses air pushed through ductwork for heating purposes takes advantage of forced air heating. In other words, this term refers not to your furnace, but to the delivery method of the heat throughout your home. Forced air heating is possible with electric or gas furnaces, or a heat pump. Any issues with this delivery system that aren't directly related to the furnace likely have to do with the duct work, which costs between $35 and $55 per linear square foot to repair, or the air handling unit.

Fitting a furnace with an electrostatic filter, which uses an electrical charge to help trap particles, or a high-efficiency particulate-arresting (HEPA) filter can reduce the amount of dust blown through the heating system. That might help people with asthma or other chronic lung diseases, but there's little evidence that other people need such filtration.

Furnace replacement in Denver is necessary if your furnace is broken beyond repair or if it is more than 15 years old. Old furnaces are very inefficient (they use more power and gas than newer ones) and they can even be very hazardous to your health and home. Furnaces are controlled fires, and when the control systems for said fires are out of date or malfunctioning, the safety and wellbeing of your home are in jeopardy. So if you have an old or malfunctioning heater, then give our furnace replacement company a call today.
