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!

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!

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

FAQs

Whether a repair is worthwhile depends on the age of the system, the nature of the fault and the overall condition of the unit.

If the system is relatively modern and the issue is minor, repairing it is often the most cost-effective option. However, if the unit is older, inefficient or experiencing repeated breakdowns, replacing it with a newer, more energy-efficient model may prove better value in the long term.

During our assessment, we’ll explain the condition of your system and provide honest advice on whether repair or replacement is the most practical solution.

Air conditioning systems contain refrigerants that are regulated under F-Gas legislation, meaning only certified engineers are legally permitted to handle and repair them.

Attempting repairs without the correct qualifications, tools and experience can lead to further damage, safety risks or voided warranties. Even seemingly minor faults can involve electrical components or pressurised systems that require professional attention.

For safety, compliance and reliable performance, air conditioning repairs should always be carried out by a qualified engineer.

The cost of repairing an air conditioning system depends on the type of fault, the parts required and the overall condition of the unit.

Minor issues such as electrical faults or blocked filters are typically less expensive to resolve, while more complex repairs involving compressors, circuit boards or refrigerant leaks will cost more.

Following an on-site assessment, we’ll provide a clear, no-obligation quotation outlining the recommended repair and associated costs, so you can decide how you’d like to proceed.

Yes. If your system has lost refrigerant due to a leak, it may require a regas or recharge.

However, refrigerant does not get “used up” under normal operation. If levels are low, this usually indicates a leak. In these cases, we first carry out a full inspection to locate and repair the fault before safely recharging the system.

All refrigerant work is carried out by REFCOM certified engineers in line with current F-Gas regulations.
