HVAC maintenance services: the ten checks that prevent most breakdowns
Most systems benefit from professional maintenance at least once or twice a year, and doing it before June and before winter is where it pays. Here is exactly what our tune-up covers.
HVAC maintenance services are the scheduled inspection, cleaning and testing that keep a heating and cooling system running efficiently through a year. Our seasonal tune-up covers ten things: air filters, the exterior condenser unit, the evaporator and condenser coils, refrigerant levels, electrical connections, ductwork and vents, the thermostat, condensate drain lines, fan and blower performance, and a full professional inspection. Doing it before summer and again before winter keeps the system efficient when it is working hardest, and it keeps manufacturer warranties valid.
Everything this service includes
Air filters
Examine and swap out the filters. A restricted filter is the most common cause of a system that will not cool.
Condenser unit
Clean the exterior condenser unit so it can reject heat properly in the summer.
Coils
Service the evaporator and condenser coils.
Refrigerant
Verify refrigerant quantities and check for leaks.
Electrical
Inspect electrical connections, contactors and the disconnect.
Ductwork and vents
Check the ductwork and air vents for leaks, damage and blockage.
Thermostat
Test thermostat functionality and calibration.
Condensate drains
Clear the condensate drain pipes so the unit does not overflow onto the floor.
Fan and blower
Examine fan and blower performance.
Full inspection
Arrange for expert servicing of anything we find that needs attention.
How the job runs
The same four steps whether it is a repair, a replacement or a seasonal tune-up.
Spring before the heat, autumn before the cold. We will also take an emergency call any time a system fails.
Filters, condenser, coils, refrigerant, electrical, ductwork, thermostat, drains, blower, and a full inspection of anything we find.
What we did, what we found, and anything that needs attention now rather than next season.
If the system is running well, we tell you it is fine. If a component is heading toward failure, we explain why and quote the repair in writing.
When to schedule, and how often
Figures are our own and are current as of this year. Final pricing depends on your system, your home and the work involved.
| Season | When | Why |
|---|---|---|
| Spring | Before June | The system is about to run hard for the summer, and every refrigerant and airflow fault shows up then |
| Autumn | Before the first cold night | Heat is about to be tested, and a failed heat pump or furnace part is an emergency call |
| Twice a year | Spring and autumn | Keeps the equipment running efficiently, keeps warranties valid, and catches faults before they become failures |
| Commercial systems | Twice a year | Commercial HVAC systems should be serviced twice a year |
| After any repair or renovation | As part of the visit | A disturbed system should be checked before it is left running |

Common questions
Most systems benefit from professional maintenance at least once or twice a year. For residential systems we recommend a spring service before June and an autumn service before the first cold night. Commercial HVAC systems should be serviced twice a year as well.
Ten things: examining and swapping air filters, cleaning the exterior condenser unit, servicing the evaporator and condenser coils, verifying refrigerant quantities, inspecting electrical connections, checking ductwork and air vents, testing thermostat functionality, clearing condensate drain pipes, examining fan and blower performance, and arranging expert servicing of anything we find that needs it.
It is worth it because a system that has lost airflow or refrigerant is already working harder than it should, and the equipment takes the wear. It is also the cheapest way to keep the manufacturer warranty valid, which often requires documented service.
We provide yearly maintenance plans that keep your system reliable and certified, and commercial preventative maintenance contracts for business customers.
Not for the routine parts. If you are not going to be there, tell us and we will send you the written report along with anything that needs your decision.
Yes. A heat pump still has filters, coils, refrigerant, electrical connections, condensate drains and a blower, so the same ten checks apply, and the additional heating mode is tested too.
