Air conditioning FAQs

Questions about air conditioning for your home?

How do I choose the right air conditioning system?

Tell us which rooms you want to heat or cool and provide their sizes. We check the capacity, unit positions and installation requirements using your photos and a home survey if needed.

How long will the installation take?

Air conditioning installation normally takes 1 to 3 days, depending on the number of units. This is the time spent installing your system once work starts.

What warranty do I get?

The manufacturer warranty is shown with your selected package or proposal. The length and conditions depend on the equipment. Keep your handover and warranty documents.

Can I spread the cost?

The payment options for your package or proposal show any available finance plans, including the deposit, term, APR and monthly payment. Finance is subject to status and lender approval.

Can one outdoor unit serve more than one room?

Yes. A multi-split system connects several indoor units to one outdoor unit. The package shows how many indoor units are included.

What should I prepare before installation?

Clear the agreed work areas and access routes. Tell us about parking restrictions, locked gates, shared access or other work taking place at the property.

What should I send if I need aftercare help?

Contact iHeat with your order reference, a description of the issue and any error message. Photos or a short video can help our aftercare team understand the problem and arrange the next steps.

Can I repay finance early?

Contact your lender for an early settlement figure. They will confirm the amount needed to repay your finance and any charges under your agreement.

Can I choose where the indoor and outdoor units go?

Yes. Show your preferred indoor and outdoor positions in your photos. The engineer checks the pipe routes, drainage, clearances and access before confirming the positions.

Will my electricity need to be switched off?

Yes, a temporary power interruption may be needed while the system is connected and tested. Tell us before the visit about any essential electrical equipment so we can plan the work.

About our installation prices

Example prices include the system, fitting and VAT. Your quote confirms the right system for your home and the price for your installation.

Installation assumptions and additional costs

Example setup: A semi-detached home in Bolton (BL1 1AA), with the number of rooms shown on the card. Small ground-floor rooms with little direct sunlight, indoor units on external walls and 5m pipework per indoor unit. A floor-mounted outdoor unit at the rear, straightforward access, suitable electrics within 5m and no condensate pumps.

If your setup differs: Room size, location, pipe routes and access can change the price. For these examples, an extra 5m of indoor pipework adds £120–£150 and an extra 5m to the fuse box adds £50–£100, depending on the system.

Other example changes: an internal-wall indoor unit £250; an upstairs room £100; high outdoor wall mounting £50; a condensate pump £150. These include VAT and describe individual changes, not a universal tariff. Specialist access and other electrical alterations are quoted individually before you order.
