Improve Air Quality with Home Ventilation

Like lungs, homes need to breathe and its air supply should be regularly circulated. Home ventilation systems work to replace the stale air within your home with a supply of fresh air from outside, creating a healthier indoor environment. Without this kind of ventilation, the air in your home is likely to become damp and unpleasant, leading to increased condensation and mould.

 

Home Ventilation Systems also prevent the build-up of airborne pollutants and can even reduce the spread of airborne viruses. Installing these systems within your home can help to increase indoor air quality and eliminate the cause of condensation.

Positive Input Ventilation by Nuaire

Positive Input Ventilation (PIV) is a method created by market leaders, Nuaire, used to ventilate homes with a single system installed in the loft. It uses proven technology to draw in fresh air from outside which is then filtered to remove harmful pathogens before being fed into the home via a ceiling mounted diffuser. As the fresh air circulates, it pressurises the home which in turn, expels excess moisture along with allergens and other pollutants.

Energy efficient
Requires minimal effort to maintain
Improves air quality inside your home

Positive Input Ventilation systems are quick, easy to install, and cost effective, making them an ideal solution for your home.

Trusted Nuaire Installers in Swindon

A comfortable temperature is only half the story. The air in your home also needs to be fresh and free from excess moisture, which is where Nuaire comes in. Founded in 1966, Nuaire is a British ventilation specialist that makes its products in South Wales, and we’re proud to install its systems for homeowners across Swindon.

Heat Recovery Ventilation (MVHR)

MVHR, short for Mechanical Ventilation with Heat Recovery, is a balanced system that removes stale air and supplies fresh air in equal measure. Moist air from steamy spaces such as bathrooms, en-suites and the kitchen is drawn into a central Nuaire MRXBOX unit and sent outside. On its way out, it warms the clean, filtered air being brought in, which is then piped to the rest of your home. Fresh air reaches every room, but the heat stays inside where it belongs.

Holds on to heat you’ve already paid for
Balanced airflow throughout the house
Filtered air for a healthier home

MVHR is the perfect partner for new builds, extensions and whole-house renovations across Swindon and Wiltshire, giving you a healthier home that costs less to run.

Benefits of Indoor Ventilation

Reduces Condensation

By keeping indoor humidity at a healthy level, PIV and MVHR both stop water droplets forming on cold windows and walls. With less moisture around, mould has nothing to feed on.

Better for Your Health

Pollen, dust and outdoor pollution are filtered out before air enters your living space. Breathing cleaner air at home can ease symptoms for people with hay fever, asthma or allergies.

Keeps Energy Costs Down

Your heating works more efficiently in a dry home, as damp air is slower and more expensive to warm. Choose MVHR and you’ll also benefit from heat that’s recovered and put back to use.

Prevents Damp Damage

Persistent moisture can ruin decorating, weaken plasterwork and leave clothes and furniture smelling musty. Ventilation stops the problem at the source, saving you from expensive repairs.

No Need to Open Windows

Your home is ventilated around the clock, so the windows can stay closed. It’s warmer, quieter and more secure, and pollen stays outside.

Quiet & Easy to Live With

Nuaire units are designed to run quietly and reliably for years. An occasional filter change is about the only maintenance they need.

Choosing Between PIV and MVHR

Both systems will leave your home fresher and free from damp, so the right choice usually comes down to your property and your plans. Here are the key differences at a glance.

Had a ducted air conditioning system installed at my property and I am so pleased with it. The team were really helpful and professional, and I definitely feel I've made the right choice upgrading to air conditioning. Thanks so much. I would happily recommend Bristol Air Conditioning to anyone looking to do the same.

5 star from start to finish! Do not hesitate to get Bristol AC in! They were friendly, professional and experts from the start. Tried a couple of national AC companies before I found these guys and so glad I waited, they have nothing on Bristol AC. Great job on the install by Robbie and Russ as well as super support from the rest of the team in the site survey all the way through to payment.

Just had an AC system installed at home by Bristol Air Conditioning and very happy and impressed by the whole process. When I initially looked into getting a home AC system, there was a lot of conflicting information and advice. As soon as Jason visited our house I was impressed by his knowledge, ideas, and honesty. He came up with ideas that minimised external trunking runs(which I was concerned about) and the best system to suit our needs. We have ended up with two wall mounted units, and two floor mounted units which work extremely well. The fitting crew were brilliant and friendly, and did an excellent job of the installation leaving all rooms clean and tidy. Overall very impressed, and would highly recommend.

Finally found the right firm for AirCon install. After years of looking, researching and receiving quotes from a number of companies, we eventually found Jason and the team. And I’m so glad we did. From the moment I met Jason to the hand over, his team have been excellent to work with. Professional, friendly and knowledgeable throughout, the team respected our home and fitted a brilliant Airzone Ducted system which is keeping us cool. Thank you, highly recommended.

Had a really good experience with Bristol Air Conditioning, from initial emails with Jason, to the install by Rich and Jack. Both guys were friendly and communicated well about the minor modifications to the initial proposal due to the nature of my property. Install was completed by the time estimate given on the day. Really pleased with the neat install of the indoor unit (no trunking visible internally) and hugely impressed by the power and quiet operation of the indoor unit, that is managing to have a cooling affect throughout the house, despite being on the top floor. Would recommend them to others.

In my job I deal with so many various contractors every single day, but I have to say Bristol Air Conditioning are the most professional company I have ever dealt with. The owner who quoted me for the job was friendly and approachable, and then Richard who fitted my unit was also so helpful and patient with instructions how to use and maintain my aircon. I highly recommend them to anyone!

Excellent experience with Bristol Air Conditioning. Initial system design and layout by Jason was very good, minimising trunking on internal walls (unlike our other quote). Price was competitive for good quality units. Luke and Jack were brilliant on the two installation days - turned up when they said they would, worked very efficiently and tidily, explained the system controls to me after it was up and running. The end result is excellent and looks extremely professional. As of early May we’ve already used it to cool a little but this week with some unseasonably low temperatures we’ve also used the lounge unit to provide some warmth first thing in the morning. The system is incredibly responsive. Looking forward to using it when we have our first summer heatwave of 2026!

Had my house fitted with air conditioning by Rich and his team, couldn't be happier with the result. Even with supplier issues they still managed to complete the work in under two days. Highly recommend them to anyone looking for a professional installation.

Bristol Air Conditioning came to me as recommended by a work colleague. There service was 5 star, from first contact to shaking Rich’s hand as he left after installation. Jason came to conduct the survey and not a WhatsApp/ FaceTime video call as others. There was zero hard sell and was totally accommodating, his BAC quote was very competitive. I had two units fitted in two bedrooms, this took two days and Rich was very efficient and helpful as was the rest of the team that supported the instal. As summers get warmer, and you start to think about AC in the house, there is only one place to go to Bristol Air Conditioning. Thank you.

Excellent service from these guys, overcame obstacles with professionalism and provided options, with no pressure. Wish all companies were like this to deal with, special call out to Jason for managing to source the unit where other companies couldn't and the install engineers (think his name was Luke), very tidy work and genuine nice guy. If you are on the fence looking for a professional, competitive, reliable company, Bristol Air Con/ Gas Safe are fantastic and I highly recommend them
