Warm air heating of any make, most often Johnson & Starley: servicing, repairs and upgrades.

Warm air heating benefits
Modern condensing warm air units are efficient, and some can provide hot water and cool air as well. We service and repair existing units, and fit up-flow and down-flow replacements.
- Johnson & Starley have been making warm air heating systems since 1922
- Rapid heat-up, so the house warms quickly
- No bulky radiators means more flexible room layouts and easier furniture placement
- Low maintenance once installed properly — many older J&S units are still going strong after 50+ years
- Up to 98% thermal efficiency, which cuts gas bills
- The Aquair Heat Interface Unit (HIU) keeps existing warm air ducting but connects to modern heat sources like combi boilers, ASHPs and electric boilers
- Aquair lets you move to a greener heat source without ripping out the ducting
- Save over 28% on fuel compared to older non-condensing models
We work on every make of warm air unit, not just Johnson & Starley. Ring 01622 474008 or request a call back.

Our Testimonials
Reviews from homeowners, landlords and businesses we’ve worked for.
I have used Plumbusters for years for servicing my boiler and some great small jobs. This time it was a new boiler moved up two flights of stairs. All work was neat and tidy, with some fantastic pipe work, like a work of art. Considering the effort to take up carpet and floorboards, there are no corners cut and the best job done, not the quickest job just to move on to the next customer. Even the outside plastering of the old outlet pipe was made to look like bricks! At the end there was a full walk through to make sure everything was working and 2 follow up checks. Great job.

Having only just moved into a new home, we were reliant upon recommendation by the previous owners. Plumbusters have been remarkably responsive and did an amazing job that turned out to be far more than first anticipated. We now have a swanky streamline vertical radiator in our family room along with two extra radiators on two upstairs bedrooms. Faultlessly clean, Grant gets our vote today. Thanks to you all. Now have you down as our preferred company for all things plumbing related. Best wishes. Mike & Joanne

We found the engineer sent from Plumbusters to be very helpful and knowledgeable and clean and tidy in his work. They were quick to respond and reliable and professional while in our house. We would be happy to recommend them to anyone who is looking for a plumber.
