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.

Debunking Ventilation Myths: AVT’s Answers to The Biggest HVAC Falsehoods Posted on 01/08/202401/08/2024 by Ella Walker Ventilation systems are the unsung heroes of modern buildings. Every day, they work to ensure that we breathe clean air and enjoy a comfortable, year-round climate. But despite decades of improving the buildings in which we live and work, they’re still the subject of so many myths and misconceptions.In a typical month, our engineers and in-house experts hear different versions of the same ventilation myths over and over again. But this post gives you the truth about your HVAC system and how to keep it operating at its best.Here are five of the most common myths we hear:1. Internal Ducts Don’t Need Regular ServicingWrong! Over time, dust, debris, and other contaminants can accumulate in ducts, which leads to impeded airflow and reduced system efficiency. Regular servicing ensures your ducts remain clean and your system operates as it should. It also extends your system’s lifespan and improves indoor air quality. The alternative – avoiding regular servicing – risks increased energy consumption and potential health issues from the recirculation of polluted air. Get your next service booked today.2. Ventilation Systems Aren’t Very EffectiveWrong! Modern ventilation systems, like those offered by AVT, are designed to efficiently manage air exchange, remove pollutants, and maintain optimal humidity levels. And they deliver in the real world, not just in lab testing. Heat, humidity, and precipitation will all effect a ventilation system. But we know our systems deliver consistently fresh and healthy indoor environments – wherever they’re installed. Browse our ventilation systems.3. Mould Only Develops in Hot and Humid ClimatesWrong! If you’ve ever been in a poorly ventilated UK property in the depths of winter, you’ll instantly know mould isn’t restricted to warmer locations. All you need is moisture and organic material. From there, mould will run riot in any conditions. Cooking, showering, and even breathing can increase indoor humidity levels. A good ventilation system is the antidote, working to control indoor humidity and therefore prevent mould formation. Browse our extract fans.4. Indoor Air Quality Doesn’t Affect HealthWrong! So many people underestimate the impact of indoor air quality on health. Research from the World Health Organisation shows that more than four million people die early every year due in part to poor indoor air quality. In those environments, respiratory problems, allergies, and even cardiovascular disease become an even greater risk. Good ventilation is key. Browse our air handling units.5. Open Windows = Optimal Indoor Air QualityWrong! Yes, getting some fresh air into the building can sometimes help with ventilation. But it’s definitely not the best way to improve indoor air quality. Outdoor air carries all sorts of nasties, including pollen, dust, and vehicle emissions. If they come into your building unchecked, you might even be making the indoor environment worse. Instead, it’s wise to invest in a HVAC system that filters and conditions the air. Get specialist advice today.Don’t Fall Victim to These Ventilation Myths!Our friendly team of experts is always ready to help you achieve the best possible indoor environment. So, if you’ve got any concerns at all about your ventilation system or indoor air quality, don’t hesitate to get in touch.
