HVAC maintenance: why your system needs a regular ‘MOT’ check – and how to do it Posted on 29/04/202529/04/2025 by Ella Walker Do you make this common HVAC maintenance mistake?Most car owners use their vehicles every day. The physical act of getting into their car gives them a constant reminder to ensure it’s well maintained, so each year they book their MOT and do their best to keep it in serviceable condition. But when it comes to HVAC systems, there’s often very little physical interaction with the machinery involved. So even though buildings rely on their HVAC systems every say of the year, it’s easy to forget that regular upkeep and servicing is necessary. It’s time to move HVAC maintenance up your priority listPlanning and investing in a regular HVAC maintenance schedule offers four main benefits. It can:Avoid costly downtime, by preventing potential problems from developing rather than simply reacting to them when it’s too late. Maintain high performance levels and consequently guarantee better indoor air quality for longer. Decrease your company’s environmental footprint, by ensuring your system is running as efficiently as possible. This also has the benefit of reducing your overall energy costs. Extend the expected lifespan of your HVAC system and help you to avoid costly replacement programmes. Each year, you should aim to clean the outdoor units, check the electrical connections, and add the correct lubrication to mechanical components. By doing this, you’ll avoid early wear-and-tear, making the equipment last longer and instantly increasing the ROI of your investment.Air Vent Technology’s recommended HVAC maintenance scheduleThe engineers in Air Vent Technology’s SES department see the same issues arise over and over again. As a bare minimum, we recommend all site managers commit to the following maintenance schedule for their air handling units:Quarterly:Inspect all filters. If they’re heavily soiled, replace them immediately.Half-Yearly:Use a brush to carefully clean the fan impeller. This prevents undue dirt build-up and stops the impeller becoming unbalanced. Inspect the coils to ensure no foreign material has accumulated on the fans. If necessary, use a soft brush to clean the fins with a mild detergent solution. Remember: go gentle. Make sure you don’t damage the fins. If you’re regularly finding debris on the fins, check the filtration system. Clean and lubricate damper cogs, blades, and frames with a PTFE or silicone oil aerosol lubricant.Yearly:Check the security and integrity of all fasteners. Pay particular attention to the impeller fixing on the fan shaft. Inspect the unit’s paint finish. If necessary, repaint with a suitable touch-up paint. Check anti-vibration mountings and flexible connections for signs of perishing or damage.Alternatively, get the experts to help outFor a bespoke service plan designed specifically for your air handling units, email our SES department.

How to Ventilate Your Residential Property During Winter Posted on 28/11/202428/11/2024 by Ella Walker As the winter months roll in, ensuring proper ventilation in your home or residential property is just as important as keeping it warm. The dark chill outside might mean you focus more on indoor warmth. But it’s also essential to maintain proper airflow to combat issues like mould, condensation, and indoor air pollution.Here at Air Vent Technology, we know a thing or two about creating a comfortable, healthy indoor environment – even when it’s so cold outside that slippers, blanket, and a hot drink seem the only sensible choices. This article will explain why ventilation matters in the coldest months and how to keep your home free from ventilation problems during the depths of winter.Why Winter Ventilation MattersIndoor air can be up to 10 times more polluted than outdoor air. So fresh indoor air isn’t just something to dismiss. It’s actually a critical factor for your family, tenants and residents’ long-term health.One of the leading causes of wintertime condensation and mould is excess humidity. Everyday activities such as cooking, showering, and even drying clothes release moisture into the air. If you’ve ever been in a poorly ventilated kitchen – with hobs blazing, pans simmering, and windows fogging up – you’ll know exactly how quickly condensation can form.Without proper ventilation, this humidity has nowhere to escape, leading to damp walls, musty odours, and even health problems like respiratory issues.But that’s not all. Stale indoor air can also spread germs and exacerbate illnesses – which is far from ideal with flu season fast approaching.Top Tips to Keep Residential Properties Ventilated in WinterWhen there’s frost on the ground, very few of us would consider opening windows to circulate fresh air. But here’s the good news: ventilation doesn’t have to mean sacrificing comfort.Here are some simple and effective ways to keep the air flowing in your property while still preserving warmth:• Heat and ventilate unused roomsSpaces like conservatories and guest rooms often get overlooked in winter. But keeping these areas heated and ventilated will help to prevent stagnant air and moisture build-up.• Let in fresh air (briefly)It only takes five minutes for fresh air to circulate in a room. Open a window, go make a cup of coffee, and by the time you’re done you’ll have let in enough clean air without the indoor temperature drastically dropping.• Clean your extractor fansIn kitchens and bathrooms, these are your best friend. Keep them clean – and don’t forget to change the filters. A well-maintained fan is one of the easiest ways to control humidity.• Ventilate while showeringRunning hot water indoors while outdoor temperatures are plunging is a perfect recipe for window condensation. Before you get in the shower, open the bathroom window or turn on an extractor fan. This will help to release steam immediately and prevent any build-up.• Rethink drying clothesUse a tumble dryer instead of radiators for drying clothes. Radiators add unnecessary moisture to the air, increasing the likelihood of condensation.AVT Products for Hassle-Free Winter VentilationLooking for a reliable ventilation system in your property?
