Indoor Air Quality Services in Simcoe County & Muskoka

Helping local families breathe easier for over 10 years, SMHC is your partner for cleaner, healthier homes.

We know that in Simcoe County and Muskoka, we spend a large portion of our year indoors—especially during our long winters. When the windows are shut tight to keep the heat in, it’s easy for dust, allergens, and stale air to build up. Whether you are struggling with seasonal allergies, dry winter air, or concerns about mould, our team is here to help you find a solution that fits your home and your budget.

We don’t believe in scaring you into buying expensive equipment. We believe in education. We take the time to assess your home, explain your options clearly, and install systems that make a genuine difference in how your family feels.

Why Locals Trust SMHC for Air Quality

Improving your air quality isn’t just about buying a filter; it’s about understanding how your home breathes. Families from Orillia to the cottage country of Muskoka choose SMHC because we understand the specific environmental challenges of our region.

What you can expect every time:

Local Climate Knowledge

We understand the unique challenges here—from the high humidity of lakeside summers that encourages mould, to the bone-dry air of a January freeze that causes static and dry skin. We recommend solutions that work specifically for our local climate.

Certified & Safety-Focused

Our technicians are fully licensed (including Residential Air Conditioning Systems Mechanic - 313D) and hold Joint Health and Safety Training Certifications. We take the health of your home seriously.

Honest, Educational Service

We aren't here to sell you a gadget you don't need. We explain why your air feels stale or why the dust won't go away, and offer transparent, no-pressure recommendations.

A Reputation Built on Trust

With 1,200+ five-star reviews and an A+ BBB rating, you are choosing a team that your neighbours already rely on to keep their homes healthy and safe.

What Causes Poor Air Quality?

Every home is different. Whether you are retrofitting a century home in downtown Orillia or updating a modern cottage in Muskoka, we have the right tools to clean your air.

Heat & Energy Recovery Ventilators (HRV/ERV)

Modern homes are built airtight for efficiency, but that traps stale air inside. HRVs and ERVs swap that stale indoor air for fresh outdoor air without losing your heat. It’s like opening a window in the middle of winter, without the draft or energy loss.

Whole-Home Humidifiers

Winter in Simcoe County is dry. Low humidity causes dry skin, sore throats, and can even crack hardwood floors and furniture. We install systems that maintain optimal moisture levels automatically, protecting your health and your home.

HEPA Air Filtration

Standard furnace filters catch dust, but HEPA systems capture 99.97% of airborne particles. If anyone in your home suffers from asthma or severe allergies to pet dander and pollen, this is a game-changer.

UV Light Purification

Installed directly into your ductwork, UV lights work silently to neutralize bacteria, viruses, and mould spores before they circulate through your home. It’s an effective way to reduce the spread of germs during cold and flu season.

Mould & Moisture Control

Excess moisture is a common issue in our region. We help you manage humidity levels to prevent mould growth before it starts, keeping your basement and living areas safe and smelling fresh.

Understanding What’s in Your Air

Many homeowners don't realize what affects their indoor air quality until symptoms appear. Here is what we help you tackle:

Dust & Allergens: Pollen from local ragweed, pet dander, and road dust can circulate endlessly in your ducts without proper filtration.
Poor Ventilation: If your home feels "stuffy" or smells lingering, it’s likely a lack of fresh air exchange.
Humidity Issues: Too much moisture leads to mould; too little leads to respiratory irritation. Balance is key.

VOCs & Odours: Cleaning products, paints, and new furniture release chemicals (VOCs) that can irritate the eyes and throat.

Mike was very knowledgeable and professional. He made sure to take the time to explain what he was doing and devised a plan to address through 4 days of testing. Thank you Mike!

I have been very happy with everyone at SMHC thus far - from the quoting process to the repair of my furnace, everyone has done an outstanding job and have all been very helpful in answering all my questions! AC install is coming up next and I’m sure that will be just as great of a process! Very excited to work with them for all my future needs!

I woke up Sunday morning to a cold house Called SMHC and they sent a tech. He arrived when they said he would and got right to checking for the problem. He identified the fault and part causing the furnace to not fire and actually had the part in his vehicle. Got right to replacing it and had me up and running within an hour. Great knowledge and workmanship. Thanks SMHC.

Had a fantastic experience with SMHC - I've already recommended their services to anyone I come across looking for HVAC work of any kind, especially hydronics. Their work ethic, organization, professionalism, and quality of work are beyond expectations. These days, tours of my house start in the boiler room.
