Good ventilation is important all year round. But after months of having your windows closed, heating systems running, and fresh air in limited supply, spring is the perfect time to reset your indoor air quality.
Acting now and preparing properly for the months ahead can help to eliminate the stale air, trapped moisture, and airborne pollutants that build up over winter. At the same time, it can give you a major health boost ahead of the warmer weather and protect you from the pollen and dust that can be especially aggravating in these early months. Here’s everything you need to know.
The challenges of preparing your building for spring
Most properties, especially residential homes, rely on relatively simple extract fans. These are most commonly found in bathrooms and kitchens. But while they’re low-cost and low maintenance, they’re only marginally more effective than opening a window.
They only extract air from specific areas, and they don’t distribute fresh air evenly throughout a building, so the rest of your house can still suffer from poor indoor air quality. Any replacement fresh air comes via background ventilators and normal air leakage.
That’s why our advice for property owners is simple: when it comes to your indoor ventilation, whether it’s a house or office, you should see basic extract fans as a starting point, not a complete solution.
Why heat recovery units offer the best value and performance
For a more effective approach, it’s worth looking towards a whole-‘house’ solution. The best of these are undoubtedly mechanical ventilation with heat recovery (MVHR) systems. These offer several benefits, including:
As the weather improves, spring’s rising humidity creates ideal conditions for mould and bacteria to multiply. If existing ventilation systems are underperforming or under-powered, that risk is compounded.
But investing in a Heat recovery unit (HRU) like ClassFlo, HRPVX, or HRPSL can help to reduce allergens, remove gases from modern chemical products like hairspray and cleaning fluids, improve sleep and concentration, reduce musty odours, and support better overall wellbeing.
Don’t overlook regular maintenance
If you’ve already got a ventilation system in place, now’s the perfect time of the year to make sure everything is in good working order. As we leave the winter months, replacing or even just cleaning your existing air filters can have a huge impact.
Being proactive is key. Whether you want to consider a new MVHR installation or simply need servicing specialists to keep your existing unit in peak condition, don’t just sit back and wait.
