When winter temperatures drop and heaters fire up, many people notice an unexpected side effect: a stuffy nose. If you’ve ever wondered why your nasal passages feel clogged the moment your furnace kicks on, you’re not alone. At Thomas Hoffmann Air Conditioning & Heating, we frequently hear this question from St. Louis homeowners. Let’s break down the reasons behind this all-too-common experience — and what you can do to fix it.
These guys were great. Quick to return my call. Up front pricing. Great work on the installation. And the installers were nice and friendly. Highly recommend Thomas Hoffmann.
Hoffmann came out the same day I called them because our AC was out. The technician, Ryan, was able to get the system running again, was polite and responded to my questions. We’re off to a good start!
Thomas came over promptly I spoke with him about my concerns with my unit. Immediately got to work trouble shooting and resolved my issues. A+
Response from the owner:Thank you, James, for your kind words and for recognizing Thomas's promptness and dedication in resolving your concerns; we appreciate your feedback!
We have called Thomas Hoffmann many times and they are very prompt and very professional.
Response from the owner:Thank you, Vicki, for your kind words about Thomas Hoffmann's promptness and professionalism; we truly appreciate your feedback!
Not a customer, but witnessed one of their technicians have an episode of road rage in Clayton. I would be concerned about letting them into my house/business.
We really trust Thomas Hoffman AC and Heating. Nick Hoffman has serviced our units several times now and he is professional, knowledgeable and very easy to work with. He comes on time, so we don’t have to schedule a long waiting period. We would highly recommend this company.
Response from the owner:Thank you, Greg, for your kind words and for trusting us with your AC and heating needs; we’re glad to hear that Nick has provided you with such great service.
We’ve been looking for a locally owned small HVAC dealer for a few years. And we found it with Thomas Hoffmann Air Conditioning & Heating. We love their service technicians.

Response from the owner:Thank you, Mary, for sharing your wonderful experience with us; we're glad to hear you appreciate our technicians and their commitment to great service!

They were timely, polite, professional and they saved us from too much sweating. In a field full of pompous and arrogant technicians, these guys take the time to explain what is wrong and how they are correcting it. Other folks just assume you are incompetent but these folks take the time to educate. Cannot recommend highly enough.

Fast efficient service. Both of the gentlemen that came to my home were very help and informative not to mention polite. It’s difficult to get service advisers to appear at your home when scheduled most times they’re late or don’t show up at all. Not an issue with this team on time, clear diagnosis, quick repair. I would definitely use Thomas Hoffmann Air Conditioning again. I recommend them highly.
Response from the owner:Thank you, Anna, for your wonderful feedback! We're glad to hear that our team provided you with timely and helpful service, and we appreciate your high recommendation.

I’ve been using “THOMAS Hoffmann Airconditioning and Heating” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!
Response from the owner:Thank you so much for your continued support and kind words, Mari! We truly appreciate your loyalty and are glad to hear about your positive experiences with our services. We look forward to continuing to provide you with top-notch service in the future.

Dry Air is the Biggest Culprit
Heated indoor air is notoriously dry. As your heating system warms your home, it often reduces the humidity to levels far below what’s comfortable for your body. The dry air strips moisture from your nasal passages, causing them to dry out, become irritated, and swell slightly, leading to that classic “stuffy” sensation.
Ideal indoor humidity levelsrange from 30% to 50%. Anything lower can make breathing uncomfortable and even contribute to nosebleeds.
Dust, Dander, and Allergens in the Air
When your HVAC system turns on, it circulates air throughout your home, and with it, any dust, pet dander, or other allergens that may be lurking in your ducts or filters. If your system hasn’t been cleaned or maintained recently, you’re essentially breathing in irritants every time the heat runs, which can inflame your nasal passages.
Solution: Regularly replace your HVAC filters (every 1-3 months, depending on your home’s usage) and consider investing in high-quality HEPA filters or air purification systems to reduce airborne particles.
Mold and Mildew Exposure
Although less common, if your HVAC system harbors moisture or has poor ventilation, mold or mildew can develop inside ductwork or around coils. Mold spores are potent allergens and can trigger nasal congestion, sneezing, and other respiratory symptoms.
Red Flag: If your stuffy nose is accompanied by a musty smell when the heater is running, it’s time for a professional HVAC inspection.
Sensitivity to Temperature Changes
Some people’s sinuses are sensitive to rapid changes in temperature. Breathing in warm air after exposure to cold air outside can cause the blood vessels in the nose to expand, leading to congestion. This is a natural reaction, but it can feel uncomfortable when it happens repeatedly.
Tip: Gradually warm up your living spaces when possible. Consider wearing a scarf over your nose when transitioning from outdoors to indoors in winter.
How to Breathe Easier This Winter
At Thomas Hoffmann Air Conditioning & Heating, we believe a comfortable home is a healthy home. Here are our top recommendations for reducing winter stuffiness:
Add moisture: Install a whole-home humidifier or use portable humidifiers.
Keep it clean: Replace air filters regularly and schedule annual HVAC maintenance.
Purify the air: Consider air scrubbers, UV lights, or HEPA filtration systems.
Ventilate properly: Ensure your home has adequate ventilation to avoid stale air buildup.
