- Smells coming from the indoor unit
What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Photos of the existing unit and its label help with repairs and servicing near Chells.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- We clean the filters, coils and fans and clear the condensate drain.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- We run the system again and leave you a service record.
How to prepare
- Name a contact who can meet us at the agreed time
- Plan for pets to be kept clear during the visit
- Make sure we can reach the outdoor unit, or where it will go

Advice
Air conditioning servicing for homes and businesses in Chells
For homes with one or two units and businesses with many, we can set up a maintenance contract. We agree the visits, what each one covers and the price with your quote, and the servicing happens on schedule. Typical jobs include ice forming on the pipework or outdoor unit and noisy fans or rattling from the outdoor unit, across wall-mounted split systems, ducted systems and air-to-air heat pumps.
For most homes near Chells, a service once a year keeps the system efficient and the filters clean, and regular servicing can be a condition of some manufacturers’ warranties.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

FAQs for Chells
How often should air conditioning in Chells be serviced?
For most homes, once a year. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Is Chells in your area for air conditioning servicing?
We do: Chells falls inside our working area. To start, phone us on 07833 053749, or email if that’s easier with a few pictures.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Chells and across Hertfordshire. Tell us who should receive the paperwork.
Leave it or put it right?
When air cannot get through the unit easily, the system has to run longer to get there. Cleaning them is a small job and lets the system run as it was designed to. Waiting rarely makes an air conditioning problem smaller.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so there are no surprises.

Aftercare tips
Looking after it is simple, and it makes the next visit easier:
- Check the condensate pipe outside isn’t blocked or crushed
- Call about new noises or smells rather than waiting
- Clear leaves and debris from around the outdoor unit
After the service, you get a record of what was done, listing the work, the checks and any recommendations. File it with the system’s manual and warranty documents so the service history is in one place.
Check that the condensate pipe outside can still drain. If the outlet is blocked, the water has to go somewhere, and that’s usually back towards the indoor unit.

What else we do in Chells
What owners can safely do
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
