Letchworth Garden City: your questions answered
How do I get a quote for air conditioning servicing in Letchworth Garden City?
The easiest way is to call 07833 053749 or drop us a line with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Can you do air conditioning servicing in Letchworth Garden City?
We do: Letchworth Garden City falls inside our working area. Tell us a little about the job and we’ll take it from there.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes anything from an hour for a simple split system to most of a day for a larger installation. We book visits in Letchworth Garden City at a time that suits you, and business work around your hours.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Next come the terminals, the controller and the refrigerant side, with a leak check if the system’s size makes one a legal duty.
- A service record follows, with any faults and the options for fixing them.
Getting ready for the visit
- Tell us about any building rules, permits or sign-in
- Arrange for someone to be there to let us in
- Tell us about parking and loading

What else we do in Letchworth Garden City
What you can do yourself, and what needs us
Leave the units and pipework where they are. 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.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Aftercare tips
To keep the system working properly:
- Keep plants, bins and stored items away from the outdoor unit
- Read the warranty conditions for your brand
- Close windows when the air conditioning is running
Put the next service in the diary straight away. Many people book in spring, before the cooling season, or in autumn if they use the system for heating, though any time of year works.
Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than after a breakdown.
A customer’s words
