FAQs for Tisman's Common

Is Tisman's Common within the area you cover?

We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.

Is planning permission needed for air conditioning in Tisman's Common?

There’s no single answer: the building and the outdoor unit position decide it. Around 11 listed entries sit within 0.5 miles of central Tisman's Common. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Tisman's Common, usually Horsham council).

Will I get records for the system?

Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.

Can you look at a system you didn’t fit?

Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.

Do you install in the evenings or at weekends?

Yes, the programme is built around the site. Shops, offices, restaurants and schools all have different needs and the plan reflects it.

Which accreditations do you hold?

We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.

Can I do any of the installation myself?

No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.

Commercial air conditioning for homes and businesses in Tisman's Common

Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we’re not assessors, but we prepare systems for inspection and act on what the report finds. The work covers server and comms room cooling, ducted systems and ceiling cassettes, and people most often call us about systems that need out-of-hours or phased installation and older systems on refrigerants that are getting scarcer.

If you run a village hall or similar building near Tisman's Common, heating and cooling that warms up fast suits a space used on and off.

The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Signs you need commercial air conditioning in Tisman's Common

Older systems running on R410A face rising costs for top-ups as the GB HFC phase-down tightens supply. Servicing and repairing R410A systems is still allowed, but it’s a factor when planning a replacement.

It’s time to call us if you are dealing with:

  • Offices that get too hot in summer
  • Older systems that cannot keep up
  • New tenancies needing cooling and heating

For a church or hall like St John the Baptist, any outdoor unit needs the right consents first.

Questions to ask before booking

  • Whether the manufacturer’s warranty depends on regular servicing
  • Whether testing, commissioning and paperwork are included
  • If the figure could change on the day

What affects the cost of commercial air conditioning

Our prices page gives typical ranges, but every job is priced on its own. The quote depends on:

  • Access, including height, roofs and ladders
  • Whether it’s a one-off job or part of a maintenance contract
  • The number of rooms, units or zones

No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.

What we need to know

Simple jobs can often be priced from photos and some basics. Send what you can of the following:

  • The address and the type of property
  • Your consumer unit or fuse board
  • The rating plate or label on any existing unit

Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or send an email.

What commercial air conditioning can’t fix

In fairness, there are a few things this work will not fix:

  • Fire risk assessments
  • Carrying out the TM44 inspection itself, which needs an accredited energy assessor
  • Building work beyond the installation itself

Not sure which it is? You can call us on 07833 053749 or send an email and we will tell you honestly before you book.

What we work on in Tisman's Common

  • Wall-mounted split systems
  • Ducted systems
  • Multi-split systems
  • VRF systems
  • Server and comms room cooling
  • Ceiling cassettes

How it works

If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. For businesses, we can typically work room by room or zone by zone. The work takes a few days for a small shop or office, longer for VRF across several floors. A few pictures help us make the most of a visit to Tisman's Common.

  1. You tell us about the building and what’s needed.
  2. A site survey confirms the heat load, the layout and the access.
  3. The options, cost and timing are set out in a fixed-price quote.
  4. Installation goes ahead around the business.
  5. The system is commissioned and maintenance can be arranged.

Preparing for the visit

  • Move furniture away from the wall where we’ll be working
  • Arrange for someone to be there to let us in
  • Have the make and model of any existing unit to hand
