MANAGE HOME TEMPERATURES

Are summer temperatures making you lose your cool?

Everyone loves summer. Longer days, beach and pool fun, warm nights. But what about when temperatures edge just that bit (or a lot!) too high and your home feels like a sauna? And let’s not even talk about trying to sleep when that heatwave strikes. Absolute torture. Thankfully, we can cool your home (at a fraction of the cost of running your air con systems) with our roof heat extraction ventilation systems. Our systems can drop the temperature in your house by up to 10 degrees allowing you to sleep comfortably at night without running your air conditioing systems all night long.

What our customers say

Xchange Air transformed our damp basement into a dry, usable space. Highly recommend!

I found the staff at Ultrafan very helpful and responsive from the first contact through to the final part of the installation process. On the day of the installation, the team were on-time, cleaned up after themselves and were very professional. They were also very patient at trying to work through the initial issues with the Wi-Fi/app set-up. Despite the expense, I am very happy to no longer towel down my windows daily during winter and have dry clothes in my wardrobe/drawers. I would highly recommend them to anyone experiencing the same damp issues in their home.

Great service. Came for an initial consult and told us what we needed to do with a couple of different options, corrected some common misunderstandings about under floor ventilations and rectification works, and booked us in for the next week. The day after the install our in-home humidity had dropped from an average 68-81% each day, to 51%, and has continued to stay around 41-55% since. Plus our rooms have lost that chill they used to have. Xchange Air were life savers.

The two gentleman that turned up were very professional, approachable and happy to discuss anything and everything regarding the under floor ventilation SYSTEM installation at my premises. When Martin attended my premises to inspect and advise on what he recommended for our premises, he had the exact same approach to the task at hand. A big thank you to Martin and the entire xchange air team.

Ventilation system just installed in our cellar and adjoining rooms. Job was organised, quoted, and completed quickly and beautifully- great attention to detail and a very tidy finish. They even vacuumed the house afterwards. Recommended!

Did a great job with the sub-floor underfloor fan. Had it for about 6 months now and it's completely removed the damp smells and dried out the sub floor space now. We had NO CONDENSATION AT ALL this winter on our windows which was amazing, and due to the lower amounts of humidity in our house now. Well done and highly recommend, very professional team.

I have used Xchange air's service for many years. Martin is honest and reliable. I had mould issues and bad ventilation, when I got the filtration system installed, all my worries had been resolved. The system has worked so well that I am reinstalling it my new place. Its the best! I couldn't be happier!

Called about a month ago because we have a constantly musty smell in one room even though it’s been treated for damp and has a damp course. Martin came and quoted quickly and Dave did the installation within a few days. 10 days after installation and there is no musty smell, I really think they’ve fixed it. And we’ve just had the worst rain EVER! Time will tell if this is the solution but so far so good. Xchange air have been east to deal with from start to finish, reasonably priced and very professional at installation. 100 percent recommend.

Too Much Condensation

Struggling with excessive condensation? The wrong heating and cooling choices can cause condensation – leading to mould problems.

Reduce condensation

Home too hot

Stay cool during the summer with our roof ventilation systems. We can’t fix how much sun your home gets, but we can help with home cooling products to prevent your home from becoming a sauna.

Cool your home

House Too Cold

Ensure your home stays warm in winter. Cold drinks are great, cold homes not so much. The right home ventilation products can stop your home becoming a refrigerator.

Heat your home

House Too Damp & Mouldy

Our subfloor ventilation systems effectively reduce dampness, protecting your home and health. Forget about cleaning mould – stop it from developing in the first place.
