    "Paul was brilliant from start to finish I asked for a quote which he gave within a day of visiting my house he agreed a date and turned up on time and completed 5 jobs in my house to an extremely high standard and asked for no cash up front or payment until I was completely delighted with the finished job which I totally was, and I was further pleasantly surprised when the final invoice was substantially below the original quote as Paul completed the work quicker and with fewer parts than estimated. Who expects a tradesman to that these days except Paul from Alliance Heating and Air Conditioning. I’d totally recommend this company and will definitely use them in the future."

    "Cannot say a negative thing about the work Paul and his team did installing 2 new Mitsubishi air con units in our home after our 2 previous over decade old units died. He and his partner did an amazing job getting new air con units installed, including one fully running on day one as we had just had a baby and were in the middle of the hottest days in June on record. Both units have now been installed professionally and our house is lovely and cool. The units are quiet and efficient. Paul worked with our schedule and some difficulties surrounding a party wall. We will not hesitate to call Alliance again for both our yearly service of the air con units but also for our boiler."

    "Paul fitted our Baxi boiler, and as part of the guarantee, it needed to be serviced annually. Paul has done this for years now and we are very pleased every time."
