What do heating and cooling services include?
HVAC systems play a crucial role in our interior comfort. With just a touch of a button, they are fully capable of keeping us warm during winter and cool in the summer. Heating and cooling services include professional installation, maintenance, and repairs so you can maximise these benefits for a much longer time.Â
Heating and cooling experts are often familiar with almost any make and model of equipment from different HVAC companies. If you prefer hiring a trained technician to handle a specific brand, we can also find a qualified person for you. Here are some of the services that you can book from us:
Heating and cooling installation
Heating and cooling installation specialists can help mount single or multi-split systems, ducted systems, hydronic heaters, evaporative air conditioners, or almost any heating and cooling system you need. They typically get the job started by calculating how much space your heater or cooler will cover. If required, they can also help you find the best spots for them to ensure optimum efficiency.Â
Some HVAC systems require electrical, plumb, and ductwork, so hiring an expert for the job is vital. They can also do a final inspection before you fully utilise your new heaters or coolers to avoid any potential risks in the future.
Heating and cooling maintenance
When it comes to heaters and coolers, a routine overhaul should always be a top priority. You can get someone to clean your vents and coils, as well as change your air filters regularly. Plus, they can also apply appropriate coating technology and protect your condenser coils from the threats of moisture buildup and corrosion.
In case you want to avoid the sweltering heat of summer and the freezing air of winter, you can schedule pre-season maintenance with us to ensure that your air conditioning is running as smoothly and efficiently before the ultimate increase or drop of the outdoor temperature.Â
Heating and cooling repair
Just like any other equipment, HVAC systems from any heating and cooling companies will age, deteriorate, and break down over time. Some parts to look out for include non-responding sensors, clogged ducts, and corroded coils. Some end-users also suffer from leaking, overheating, and corrosion building, which can all lead to even more catastrophic damage if left unattended.
Whether it's because of old age, excessive usage, or inadequate maintenance, repair experts can help you find the source of the problem and repair your heating or cooling system as necessary. They can head over to your place, readily equipped for urgent requests. In no time, they can help get your system back to normal and efficiently operating again.

Help with my boiler

Elmstead, Greater London

I have an Ideal Logic Combi 30 boiler. When I want hot water out of my kitchen tap it’s always cold and also the same with my bath/shower. I’m having to pre-heat my hot water for 2 hours just to get a little hot water. The boiler was last serviced on the 24th of January this year. I’m on a budget so please nothing overpriced if this is a simple fix. Edit from last post: I have called out some plumbers and I’ve been quoted over £2k … for a new boiler and over £1k for a fix. The problems are outlined below: Supply and replace: Plate heat exchanger Leaking cold inlet valve And sump I’m on a really tight budget. I have attached the quotes I’ve been given for a new boiler and the price for the fixes. My heating works fine but I just need hot water. I know it is better off replacing but I haven’t got the funds. Thank you.

Heatmiser Central and Underfloor Heating Repair
£200
Selhurst, Greater London, CR0
4th Aug 2025
We currently have two Heatmiser Neostat v2 thermostats installed in our home, along with an RF Switch v2 and a UH8-RF v2. One of the thermostats is used to control our radiators, while the other manages the underfloor heating system. We’ve been having ongoing difficulties getting either thermostat to consistently switch the heating systems on or off. We’ve tried resetting and re-pairing both systems several times. While they may initially appear to function correctly for a short period, the thermostats inevitably stop communicating with the RF Switch and UH8-RF devices. At first, we suspected that the issue might be linked to our old boiler (which was over 20 years old), but having replaced the boiler, the issue remains unresolved. We also attempted to relocate the thermostats closer to the RF units to improve signal strength, but this has made no difference. To date, two separate boiler engineers have tried to diagnose the issue, but neither has been able to identify the root cause or offer a solution.
