Services

Preventive maintenance may be the least exciting service we offer, but it is the one that saves our customers the most money.

You book a visit whenever you want one. Most customers book a cooling tune-up in spring and a heating tune-up in fall, and plenty book just the one.

Each visit is a measured inspection of charge, amp draws, capacitor values, temperature rise, static pressure and combustion, and you get a written record of where your equipment stands.

Components rarely fail without first drifting out of specification. Catching a capacitor at 70% of its rating costs very little; letting it take the compressor with it costs thousands.

Most manufacturers also require documented annual maintenance to keep the parts warranty in force, so regular visits help protect your coverage.

How it works

What happens at a tune-up

  1. Book a visit

    Spring for cooling, fall for heating. Book one or both, with nothing to sign up for.

  2. We measure

    We check charge, amp draws, capacitor values, temperature rise, static pressure and combustion.

  3. Clean and adjust

    We clean the coils, drains and burners, and make sure every safety control trips when it should.

  4. Written readings

    You get a written record of every reading, which is the paperwork a warranty claim is assessed against.

Common questions

Before you book

Do I have to sign up for anything?

No. You call when you want a visit, we quote it, and that is the whole arrangement. Repairs and parts are quoted separately, because a maintenance visit is about inspection and prevention.

I have several buildings. Can you cover those?

Yes. Multi-system and multi-site maintenance is common for our commercial customers, including refrigeration equipment alongside the HVAC. Call us and we will quote them all together.

Does maintenance keep my warranty valid?

For most manufacturers, documented annual maintenance is a condition of the parts warranty. Keep the paperwork — we provide it after every visit — because that is what a warranty claim is assessed against.
