What our clients are saying:

Thank you so much for your prompt response to my urgent call today for heating repairs at Fairfield. I often feel like customer service is non existent anymore but you have restored my faith that it's still out there! I know most of the calls that you receive are considered urgent by your customers however I particularly appreciate the extra effort today since I have a little 18 month old boy at home sick with a chest infection and a freezing weekend at home would not have made him any better. So you have certainly put a smile on his face. I look forward to recommending your business in the future. Thanks again for your considerate and effecient service.

Roslyn Johnson

Thanks for the great service and quote. I am impressed with the level of advice and customer service displayed by the company. The service tech arrived on-time and was able to get the heating working with a repair to the circuit board. I'm very happy that I do not need to replace the heating unit. I will be using Grech for all heating/cooling that I will ever need in the future and will tell everyone to use them as well. Thanks again

Brendan Tilson

Hi Christina,
Thank you very much for your excellent service/job provided in regards to my property. I was recommended to use you by my partner Michael from Love Real Estate Preston. I have passed your details onto all the staff in my office as I recommend they use Grech.

CarolinePortfolio Manager

Extremely good and reliable, turned up on time, delivery on time, clean professional service men. It was a pleasure doing business with them. Got on with the job I had two big units installed they worked well and had the job done in no time at all. I would recommend this business to everyone.

Hilda Aurish

I just wanted to put a note to say how pleased I am with the service and installation of our new external heating unit. The lads arrived bright and early and had the unit up and running in no time. They cleaned up, took the old unit away, and were overall very efficient. We live just around the corner from Grech in Thornbury and always try and use local businesses where possible. Thanks again...very happy and very warm.


Thanks to Frank, Phil and sidekick (sorry I don't remember his name) and John for professionalism, customer service, promptness and a job well done.

Sue Jacobs

Thank you to all those involved in installing our new heater last Monday, your company provided excellent service.

Jan Gilbertson

Phil and Sacha have done a great job. Feedback to them and to you: job prompt, men courteous and efficient - I'd be happy to recommend Grech! Hope Grech gets more work here at 422.
