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.
Positive Input Ventilation systems are quick, easy to install, and cost effective, making them an ideal solution for your home.
Benefits of Indoor Ventilation
Low Humidity Levels
Home ventilation systems remove the humidity from the air making it difficult for things such as condensation and mould to occur.

A good ventilation system in your home can greatly reduce the risk of many health issues such as headaches, respiratory disorders and allergies.
Lowers the Cost of Energy Bills
A well-ventilated home is much easier to heat than a damp one. By investing in home ventilation, you could save money on your heating bills in the long run.

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.Posted on Google![]()

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.Posted on Google![]()

Faultless service. Great guys. Made the install a clean and efficient process followed by a thorough briefing on operation of the unit. Would recommend.Posted on Google![]()
Richard Burden23 June 2026
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.Posted on Google![]()

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!Posted on Google![]()

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!Posted on Google![]()

They were fab. Very professional and installed our air con over just a few days. All the engineers were very friendly and happy to explain what they were doing/how to use the system etc. Overall I highly recommend BAC if you are looking to have air con installed in your property! Our house is so cool now!Posted on Google![]()

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.Posted on Google![]()

From start to finish Jason, Luke, Jake and Jack were professional and fantastic. Very happy, 5 stars and thank you.Posted on Google![]()

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.Posted on Google![]()
Dan Garty7 April 2026
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 themPosted on Google![]()

What a pleasure doing business with this company; from the initial quotation and visit by Jason to the admin by Leannne and the fitting by Tom and Jack. Extremely clean and professional workers and a company who I would thoroughly recommend to anyone. The kit ((Mitsubishi) is amazing and has already made as difference in the hour since it has been commissioned. Thank you for a job well done.Posted on Google![]()

Brilliant job by Rich and Jack installing a single wall unit in my bedroom. Everything went to plan, from the initial consultation to the final installation, which took less than six hours. Both of the guys were friendly, professional, and a pleasure to deal with. I'll be recommending Bristol Air Conditioning to all of my friends and neighbours.Posted on Google![]()

Very good service. Had a service undertaken on a old system. Richard was very efficient and informative. The system came up really clean
