Planned Maintenance

Air conditioning units require regular servicing to ensure they’re still operating efficiently and providing you with the heat or cool you require in your home or workplace. Whether your system was installed by us or someone else we have a maintenance package for you.

Repairs and Replacements

Air conditioning systems have an average life expectancy of 15 years but during this time some will need repairs. Our fully trained and qualified service engineers are well placed to provide accurate diagnosis and cost effective repairs.

Due to the phase out of refrigerant R22 we are currently replacing these old systems with the latest minimal ozone depleting systems using either R32 and R410a refrigerants.

What our clients have to say

“Thank you for all your help and advice with our amazing domestic air conditioning unit. From our first meeting you explained everything clearly, showing where the installation would sit, and how it would work. You were the only company who told us that only 5% VAT was applicable to certain types of heating and cooling  units.  The engineers who did the installation were lovely and they took great pride in their workmanship.  We are delighted we chose AAC. We have, and will continue to recommend you.  We also strongly believe we have received good value for money. Many thanks again.”

Jackie Finer, Bricket Wood
