Frequently Asked Questions

Do you provide certification and reports?

Yes. Where required, we provide the relevant certificates and written documentation so you have a clear record of what has been tested, completed and signed off.

Why do you focus on diagnostics first?

We focus on diagnostics first so we can identify the real cause of the problem before recommending any work. This helps avoid guesswork, unnecessary parts replacement, and wasted cost, while giving you a clearer and more effective solution.

How do I book a visit or survey?

You can book a visit or survey using the online booking link on our website. Simply click the link and fill in your details. You can also contact us by phone, WhatsApp or email, and we will be happy to arrange a suitable time.

Should I repair or replace my boiler?

It depends on the age of the boiler, the fault, the cost of repair, and the overall condition of the system. In many cases a repair is the right option, but if the boiler is older, unreliable, inefficient, or repair costs are high, replacement may be the better long-term investment. We can assess your system and give honest advice based on the most sensible option.

Do you work on higher-end or complex domestic systems?

Yes. We regularly work on higher-end and more complex domestic systems. With many years of hands-on experience and a high level of training across plumbing, heating, electrical, air conditioning and renewable technologies, we are well placed to diagnose faults, improve performance and carry out specialist upgrade work where a more knowledgeable approach is needed.

 Trustindex verifies that the original source of the review is Google. Lee and the Berkshire HVAC team pulled out all the stops to get our air conditioning installed before my husband came home from hospital. Lee even came out at the weekend to fit it, showing genuine empathy for our situation. His workmanship was outstanding—he was clean, tidy, and clearly a perfectionist who takes great pride in his work. The end result is a wonderfully cool and impressively quiet bedroom, which has made such a difference. Thank you, Lee and the Berkshire HVAC team, for your exceptional service. I wouldn't hesitate to recommend you.

We couldn’t be happier with the service Lee provided installing our two air conditioning units. From the very beginning, he was honest, professional, and incredibly knowledgeable. He kept us informed throughout the whole process, communicated brilliantly, and always made sure we knew what was happening and when. The installation itself was completed to a really high standard, and everything was left clean and tidy afterwards. It’s clear that Lee takes great pride in his work and genuinely cares about doing a quality job. We wouldn’t hesitate to recommend Lee to anyone looking for air conditioning installation or any other work. Excellent service from start to finish, thank you!

 Trustindex verifies that the original source of the review is Google. I recently had a problem with my boiler. The issue turned out to be more complicated. Lee kept me informed throughout the whole process, took the time to explain things and completed the work with a great result. I felt I was dealing with a professional and honest business and would definitely recommend Berkshire HVAC. I am delighted to see that they are undertaking installation and maintenance of Air Conditioning systems. With the way the climate is going I may well be considering this in the future!

We had a Fujitsu air conditioning unit installed in our bedroom last week and we’re very happy with it. From the initial contact to book an appointment to look at the job, to the final completion Lee was professional and communication was excellent. Options for different price points were offered and explained. Not once did I feel like a more expensive option was being pushed. The work was completed efficiently and Lee made sure to tidy everything up for a sleek finish. It wasn’t an easy installation thanks to some layout logistics of our house, but where others shied away from this, Lee took it all in his stride. Highly recommend Berkshire HVAC.

 Trustindex verifies that the original source of the review is Google. Lee quickly and efficiently fixed the underground water leak, with  very little disturbance to kitchen.  He had to cut out the bottom of a cupboard and dig down to locate the leak.  1st class job.  Thank you

 Trustindex verifies that the original source of the review is Google. Lee did an outstanding job fitting a New Gledhill hot water cylinder including pipework . He also went out of his way to look into fitting a new bath tap because the shower attachment had broken off due to wear. He managed to take off the attachment that was broken thereby saving us money buying a completely new tap. His work is to done to the highest standard with the ability to solve problems efficiently and quickly. I really can't recommend him highly enough. A BIG thank you Lee!

 Trustindex verifies that the original source of the review is Google. Lee has done a great deal of work for us when we had a large extension done on our house. He installed our underfloor heating in our downstairs area and fitted a whole new heating system as well as two new bathrooms and the plumbing for our new kitchen. Our experience is that his work is to the highest quality. He's meticulous with his attention to detail, talks you through each job, and nothing is too much trouble in order to get the best results. We can't recommend him highly enough.

 Trustindex verifies that the original source of the review is Google. I had an excellent experience with Lee from Phase 1 Plumbing and Heating. He was professional, punctual, and extremely knowledgeable. Lee quickly diagnosed the issue with my leaking pipe and explained everything clearly before starting the repair. The work was done efficiently and to a very high standard. He even cleaned up the area afterward, leaving everything spotless. The pricing was fair, and there were no hidden fees. I would highly recommend Phase 1 to anyone in need of plumbing services and will definitely call them again in the future!
