The last time our Heating plus Air Conditioning professional came by the condo to take care of some easy repair, he said that it would be a fine method to perform air duct cleaning. I truthfully hadn’t thought about the air duct plus it had been a long time since the two of us had a air duct cleaning done. It must’ve been 4 years to be honest. I knew too that you are supposed to get your air duct cleaned every other year, but some people say you can get away with 5 years depending on your air quality plus what style of air filters you use. Naturally if you use something love HEPA filters which pulls a fine 99.9% of contaminants from the air, you can go much longer without having common air duct cleanings. And also, a substantial factor is if you have pets because pet hair plus dander will be quick to clog up your air filters plus your air duct. So I told the Heating plus Air Conditioning worker he could proceed with the air duct cleaning. I kept telling him that I should have had it done much sooner. He said it was a fine thing I was staying on top of it regardless because it helps a lot with the air quality in your home. This is especially fantastic for people with dust sensitivities. I have legitimately mild dust sensitivities myself, but I can really notice the improvement in air quality after the air duct is cleaned, but just after the guy was finished with the job, I was feeling so much better in the condo because the air quality was so much better. I suppose 4 years is absolutely stretching it when it comes to getting your air duct cleaned.
