Fewer breakdowns
Dirty coils, blocked drains, worn fans and slow leaks are caught and fixed on a scheduled visit, not on the hottest day of the year or during a Saturday service.
Commercial planned preventative maintenance
Stop paying for breakdowns. Scheduled servicing by our own REFCOM F-Gas registered engineers keeps your plant efficient, compliant and running, with 24/7 breakdown cover behind it.

Why PPM
Air conditioning and refrigeration plant that is never looked at fails at the worst moment. A planned programme finds problems while they are still small.
Dirty coils, blocked drains, worn fans and slow leaks are caught and fixed on a scheduled visit, not on the hottest day of the year or during a Saturday service.
Clean heat exchangers and correct refrigerant charge mean the plant does not work harder than it needs to. Efficient plant costs less to run every day.
Refrigerant leak checks are a legal duty for most commercial systems. We carry them out, record them and keep your paperwork in order.
Regular servicing protects compressors and keeps manufacturer warranties valid, so you get the full life from your investment.
Maintenance plans
Every site is different, so every programme is built around your equipment and how you use it. Here is how most of our commercial customers start.

What we maintain
We maintain Mitsubishi Heavy Industries, Daikin, Mitsubishi Electric, Samsung and other leading brands, including plant we did not install.
F-Gas compliance
Under the F-Gas Regulations, owners and operators of most commercial air conditioning and refrigeration systems must have refrigerant leak checks carried out by a certified engineer, every 12, 6 or 3 months depending on the refrigerant charge. Records must be kept and leaks repaired without delay.
We work out the CO2 equivalent of every system on your site, set the right inspection frequency and keep the logbook up to date, so you are always audit-ready.

Planned preventative maintenance (PPM) is a scheduled programme of servicing that keeps commercial air conditioning, chillers and refrigeration efficient, compliant and reliable. Optimal Heating & Cooling designs PPM contracts around your equipment, delivered by our own REFCOM registered engineers.
PPM means servicing your plant on a fixed schedule rather than waiting for it to fail. Each visit follows a checklist for the equipment type, any faults are reported with recommended work, and every visit is recorded. For most businesses it is cheaper than repeated emergency call-outs, and it avoids the lost trading time that comes with a breakdown.
Most commercial systems must be leak checked by a certified engineer at set intervals, depending on the refrigerant charge. We calculate the CO2 equivalent of your systems, set the correct inspection frequency and keep the records up to date, so you stay compliant and audit-ready.
Most customers choose one planned visit a year (Essential), two seasonal visits (Standard) or quarterly visits with priority cover (Comprehensive). We confirm the right schedule after a free site survey and send a fixed written quotation. See our servicing page for domestic prices, or book a free site survey.
