Our Core Values

Our Customers Say…

“I have been working with AspenAir since 2006 and have found them to be very professional, efficient and they always aim to provide a first class service. In an event of emergency, they always responded quickly.

I would recommend AspenAir to any company looking for a total air conditioning installation, maintenance and service solution and have no hesitation in recommending AspenAir for inclusion on your tender list. ”

Neil Timpson, OI Manufacturing

“Aspen worked for the Berkeley Hotel part of the Maybourne group for 3 years following their successful bid to win the contract to install 2 Daikin systems covering 13 luxury guest bedrooms and to also take over the complete service and maintenance of a further 214 units.

We have found them extremely professional and their staff are courteous and sympathetic to the difficulties in working within a live hotel environment.”
