Why Indoor Air Quality Matters During Flu Season

When flu season hits here in Monroe County and the Toledo area, keeping the air in your home clean can make a real difference in how you feel. Since most of us spend nearly all our time indoors, it’s important to make sure the air we breathe is as healthy as possible.

Where Indoor Pollutants Come From

Your home can collect all kinds of particles you may not even notice—things like viruses, bacteria, pollen, dust mites, pet dander, and mold. Everyday activities such as cooking, cleaning, or even using certain paints and products can also release chemicals into the air. Over time, all of this adds up.

How Poor Air Quality Affects Your Health

Breathing in polluted air can lead to headaches, fatigue, coughing, or irritated eyes. And during flu season, poor air quality can make symptoms worse or make it easier for viruses to spread. That’s why taking small steps to improve the air in your home can have a big impact on your comfort and health.

Why Air Quality Testing Helps

Air quality testing gives you a clear picture of what’s floating around in your home—whether it’s mold spores, dust, carbon monoxide, or chemical vapors. Once you know what’s there, it’s easier to fix the problem and create a healthier space.

Don’t Forget Your HVAC Filter

Your HVAC filter plays a huge role in keeping your air clean. When it’s dirty or clogged, your system has to work harder and pollutants slip right through. Checking and replacing your filter every 1–3 months is one of the simplest ways to improve indoor air quality.

When to Consider Duct Cleaning

Over time, your air ducts can collect dust, allergens, and even mold. Having them inspected and cleaned periodically helps prevent those particles from circulating through your home again and again.

Keeping Humidity in Check

Dry winter air can make it easier for viruses to spread, while overly humid homes can encourage mold and dust mites. A balanced level—usually between 30% and 50%—helps keep your air healthier and more comfortable. Humidifiers or dehumidifiers can help you maintain that sweet spot.

How Air Purifiers Can Help

Air purifiers with HEPA filters add an extra layer of protection by catching tiny particles like allergens and some bacteria. They’re not a replacement for good ventilation or regular HVAC maintenance, but they do make a noticeable difference.

The Power of Fresh Air

Whenever possible, letting in fresh air helps dilute pollutants and clears out stale indoor air. Good ventilation also helps reduce the spread of viruses during flu season.

Simple Habits for Cleaner Indoor Air

Here are a few easy steps that go a long way:

  • Avoid smoking indoors - Use exhaust fans while cooking - Choose gentle, low-chemical cleaning products - Vacuum regularly with a HEPA-filter vacuum

With flu season in full swing, taking a few small steps—like changing your filter, improving ventilation, or checking your home's humidity—can make your space healthier and more comfortable. If you ever want help improving your indoor air quality, we’re always here to help.

We had Micheal come out and look at our furnace and were impressed! We recently had a new furnace put in by a different company and did not have a good experience… The other company basically left us dead in the water with a bill and a furnace that was over heating! Within minutes Michael had it diagnosed and fixed! Don’t go anywhere us trust me!

Jeremy did an outstanding job!!! He also gave me additional information about my installation from the company that installed my boiler. It has been leaking since they put it in, 3 years. They have been out several times without fixing the problem. Jeremy told me what they need to do to make it stop leaking!!!! I'm never calling anyone else for boiler maintenance and repair again.

System failed because of a power outage. Jeremy knew exactly what was wrong. He couldn't have been nicer, or more helpful. Great experience.

I want to give a shout out to Complete Home Comfort. This company has gone above and beyond in servicing our heat and AC needs for many years. We just had our fall furnace service check and again, they did not disappoint. Bonus if you or spouse is a veteran. The annual service calls might as well be free. They are veteran owned. No price gouging or pressure sales of any kind. They are always very respectful of our home while working. Excellent service by people who are great at what they do and polite while they are doing it. A+ Rob and Shannon Bruley

Excellent customer service. Called them at 4 pm on a Friday. They said they could have a service tech out that night or first thing in the morning. Then I got a call about 10 mins later from the tech, saying they would be out in about 20 mins. Michael was informative and quick. Found the issue and fixed it in no time. Just great service all around!!

I had a great experience having this company out for the first time. We have lived in our house around Monroe for 4 years after we had it built and have yet to have the furnace looked at until now. Michael was very pleasant to talk to and he brought up a safety issue to me and then quickly corrected it at no cost. Even though it took him 30 seconds to fix it, he showed me what it was and just took care of it. He was very informative and because my wife is a veteran he explained to me their program for veterans and first responders. It is a wonderful program for these folks and he also told me to thank my wife for her service. Their furnace tune up special had ended but they did give me that price and that is much appreciated. I will definitely continue using this company and they are Veteran owned. If you are a veteran or first responder, I would definitely call and inquire about their maintenance program for veterans. I would like to say thank you for your service to their owner as well and to all U.S. veterans.

James from Complete Home Comfort was sent to my home in Newport, MI for a "Second Opinion," on a furnace repair. A week ago I contacted a local Monroe MI HVAC business who installed my brand new furnace in the latter part of October 2023. I was told by the technician doing the estimate repair order who is employed with the original installing company of my furnace that my furnace was no longer under warranty, that my warranty expired last year! The 2 parts were going to cost me with over $2200.00!! My original "Brand New" furnace with installation cost around $5,000.00. I was very concerned about the price and that a brand new furnace would need that costly of a repair and only 3 years old. I had done the biannual maintenance recommended with no noted issues so my gut told me call another local business for a second opinion. I am so glad I followed my gut because Complete Home Comfort had a technician at my Newport, MI within a couple of hours. James called on his way to my home, introduced himself when he came to the door. After my explanation of what my furnace was doing he got into looking at the problem. He found the other companies quoted estimate was misdiagnosed and the repair was way less. Extremely less! James also took the time to call the manufacturer of my furnace and it was never registered by the installing company which would have been a covered part if it had been registered. James was awesome, he had the replacement part on his truck and was able to have it replaced and running within minutes. I am so very happy with Comfort Home Care from my initial call earlier this morning to the repair today! I will highly recommend this business to family and friends. Hopefully I won't need it but if in the future I have problems with my furnace or central air unit, "Complete Home Care," will be the business I call . Thank you Complete Home Comfort for a job well done!

Kalim came out and was polite and helpful. He made sure he understood the concern and fixed the issue and was quick. He also out on booties without being asked which is always a plus. I had a simple drier vent issue and he was able to fix it quickly and easily.

Dude showed up early, serviced my appliances, gave me some advice on how to prevent issues with my furnace and what to look for, he was friendly and professional and they sent the same guy who had been there a year ago, I like that. I only had to take an hr off of work and honestly, if I would have left as soon as he was done I would've been 15 mins behind, thats how straight to business he was about it. For service calls and stuff, being on the ball like that is so appreciated, I've lost full days waiting for cable guys and stuff like that. 10/10 would recommend.

They came out and not only replaced our furnace, hot water tank and air conditioner condenser, they replaced all lines, and repaired the unprofessional job from the previous owner. They worked all day and were great at what they do. I will recommend them to anyone.
