Maintenance & repair
HVAC maintenance plans that pay for themselves
Think of it like changing the oil in your car. A maintenance agreement keeps your heating and cooling reliable and efficient, and we handle the scheduling.
Preventative maintenance
The cheapest repair is the one you never need
Preventative maintenance is the best way to prevent problems with your heating and air conditioning. Think of it like changing the oil in your car: regular service by a skilled technician makes your system run more reliably and efficiently.
On every visit we assess your system’s energy efficiency and fix small issues before they cause big problems. If you need a new system, we can install it, but we’d rather save you money by maintaining the one you have.
We offer affordable maintenance agreements for residential and commercial customers.

Maintenance FAQ
Maintenance questions, answered
Want to keep things running between visits? See our HVAC maintenance tips.
What does a maintenance agreement include?
Scheduled heating and cooling inspections and tune-ups covering the checklists on this page. We schedule and bill the visits automatically, and we keep an equipment history log for your system: its age, purchases and service records.
How often should my HVAC system be maintained?
Heating before the heating season and cooling before the cooling season: generally twice a year for homes with both. Spring is a good time for air conditioner maintenance.
Do you handle warranty repairs?
Yes. We do inspections, warranty work and post-warranty work on heating and cooling systems of all kinds.
Is maintenance worth it if my system is working fine?
That's exactly when it's worth it. Regular maintenance makes a system run more reliably and efficiently, catches small problems before they become breakdowns, and is the most effective way to protect your equipment.
