THS Refrigeration, Northampton's trusted AC installation specialists. Domestic and commercial supply and fit, with a 5-year Bosch guarantee and free on-site survey.
Founded in 1990, Technical Heating Services Northampton started by servicing and repairing HVAC and gas boiler systems, then from 2018 expanded into air conditioning installations across Northampton and Northamptonshire.
Our company is built on quality and attention to detail. Our primary source of new business is customer recommendations, and with a 5-star Google rating across all our reviews, that's something we work hard to maintain every day. We're not about volume; we're about doing the job properly, leaving no mess, and being the kind of company you actually call back.
Every Bosch air conditioning installation we carry out comes with a 5-year guarantee covering parts and labour. That's not a parts-only guarantee with hidden labour charges, it's full cover, with no small print.
If something fails within 5 years, we come back and fix it at no cost to you. That's the confidence we have in Bosch systems and in the quality of our installations.
We've been installing AC across Northamptonshire for over 35 years. Here's what makes our installations different.
We never quote blindly. Our surveyor visits your premises, assesses the space, plans the installation route, and gives you a fixed price on the day — no hidden costs, no surprises on the invoice.
Full parts and labour cover for 5 years on every Bosch installation. No excuses, no exclusions on normal use. If something fails, we fix it — simple as that.
Getting the unit size right is the most important part of any installation. An oversized unit short-cycles; an undersized one never gets the room to temperature. We calculate it properly every time.
We protect your surfaces throughout every installation and tidy up completely before leaving. Customers consistently mention this in their reviews, it's a standard we take seriously.
The majority of our new enquiries come via customer recommendation. That's only possible by doing the job properly, being honest, and being the kind of company people trust enough to send their family to.
Available Monday to Sunday, 7:30am to 6:00pm. Commercial installations can be scheduled out of hours on request, so we work around your business rather than the other way around.
We supply and install Worcester Bosch air conditioning systems across Northampton and Northamptonshire. Bosch is one of the most trusted names in home heating and cooling — and their air conditioning range delivers the same engineering quality, reliability and energy efficiency that the brand has been known for since 1886.
Bosch units are A+++ energy rated — among the most efficient air conditioning systems available. They run quietly, last well over a decade with servicing, and carry our full 5-year parts and labour guarantee. When customers ask us what we'd install in our own home, the answer is always Bosch.
The right system depends on your space. Our surveyor will confirm which is best for you on the free visit — but here's an overview.
Our most installed system — 90%+ of all jobs. Quiet, efficient, and suitable for almost any room. Heats and cools. Available as single or multi-split. Ideal for bedrooms, living rooms, offices and gyms.

Installed at low level rather than high on the wall — ideal for rooms with limited wall space above head height, conservatories, and settings where ceiling height restricts a standard wall mount.

One outdoor unit, multiple indoor heads — each independently controlled. Perfect for homes or businesses wanting different rooms cooled or heated to different temperatures simultaneously, without multiple outdoor units.
Call or fill in the quote form. We take basic details and book an engineer survey at a time that suits you — 7 days a week, mornings to evenings.
Our surveyor visits, assesses your space, listens to what you need, and gives you a fixed-price quote on the day. No obligation — and no guessing.
Most installs complete in a single day. We protect your walls and floors, run the pipe neatly, and test the system fully before leaving. You barely notice we were there — except for the working AC.
We walk you through the controls, confirm your 5-year Bosch guarantee, and set up a service reminder so your system stays efficient and your warranty stays valid.
We cover Northampton and all surrounding towns across Northamptonshire. Our engineers are local — so there's no call-out premium for being outside Northampton itself.
Not sure if we cover your area? Call us and ask — we cover most of the county and are happy to confirm before you commit to booking a survey.
"We had Kirk out from THS to fit our new Bosch air conditioner. They did a fantastic job and so pleased with the installation. I highly recommended using THS and have recommended them to all my family and friends."
"Kirk fitted 3 AC units and done a fantastic job with his team. They protected my walls and floors, cleaned up afterwards and left perfectly. I would highly recommend THS and their crew. Thanks for the brilliant job!"
"Top-tier service from start to finish. The engineer from THS is hands-down the best in the business. Reliable, fair pricing, and expert workmanship. I wouldn't trust my heating and cooling with anyone else."
