A modern air-source heat pump can deliver up to 4 kW of heating or cooling for every 1 kW of electricity it uses, that’s up to 300 % efficiency. Add the current £7,500 Boiler Upgrade Scheme grant and pay-back time shortens even further

An air-conditioning (air-to-air) heat pump is a reversible “fridge in disguise.” In winter it extracts latent heat from outside air, even at –10 °C and pushes it indoors. In summer, the cycle flips to pull warm air out, acting like an AC unit.

Great service and customer servicePosted onDonna ElseyTrustindex verifies that the original source of the review is Google. Do not use this company. I feel like I have been scammed and cheated- my fault for not doing more due diligence. They quoted me £700+ including VAT to have 3 AC units 'serviced', which was asked to be paid in full in advance to secure the appointment. The tech arrived and spent less than 90 minutes and only rinsed the filters under running water and advised that a 'deep clean' would be required, which would have cost a further £350. I'm sure the tech's hourly rate, but I'm sure it isn't £500/hour and the work done was completely basic. There's zero justification for the price for the work involved and when I emailed the company to raise this feedback, I have had zero response or acknowledgement. I cannot give zero stars but would if I could and STRONGLY advise not to use this company for your AC unit servicing. As a side, the tech who came to do the work, was perfectly polite, professional and efficient. If I could hire him directly again, I'd consider it but not via this company.Posted onColddegreesolutionTrustindex verifies that the original source of the review is Google. Highly recommended! We use Be Cool regularly for our breakdowns and never fail to impress! Fair pricing as well.Posted onMert AralTrustindex verifies that the original source of the review is Google. Do not use this company. They serviced my 3 Daikin AC units in July. In August, one of them started leaking. Beginning of September, one completely stopped cooling and working. These units are 3 yrs old and all of them have been perfectly fine until these guys serviced it. When I ask them to come and have a look at these issues, they keep asking for additional call out charges. Avoid at all costs!!Posted onDavid LamTrustindex verifies that the original source of the review is Google. Be Cool serviced Montagu Coachworks air-conditioning units this morning and I must imply done a fabulous job in ensuring out units was serviced to the correct standard. Manhoe was professional and wasted no time servicing our units and going the extra mile to make sure it's running as it should and efficiently, such fantastic employees should not go unnoticed in the trade. They completed the job without disrupting our site business. We will use them again in the months ahead. Thanks guys.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
