A malfunctioning HVAC system can affect your comfort, but still its maintenance is very much ignored. Even the best HVAC systems can cause energy loss, if its tuning is ignored. How much energy gets wasted will depend on your usage, climate, clogged filters, sooty flues, dirty thermostats, un-lubricated fan motors and leaky ductwork. It can hinder your HVAC performance by approximately 25%.
Generally, some maintenance tasks are DIY kind, while others need trained professionals.
Tips to handle an HVAC system
Regular HVAC maintenance
Heat pump needs annual service
- Check belts, filters and wiring, if necessary replace them
- Lubricate the moving parts
Gas fired furnace
Furnace filter need to be replaced in a couple of months, during heating season. Circulating fans needs to be oiled, yearly. Engage a technician for annual check up of –
- Heat exchanger
- Burner adjustment
Oil fired boiler
Annual maintenance of an oil-fired boiler from a trained technician is needed.
- Clean flue
- Clean & tweak fuel jets
- Replace fuel filter
AC units need less intensive maintenance. When summer starts and ends, you need to –
- Vacuum the unit
- Clean or change air filters
- Oil the motor

Engaging an HVAC maintenance company
Look for an HVAC technician, who is well-educated and has experience in the kind of system you own. A reliable company carries liability insurance & compensation policy. Ask your friends or family for recommendations.
You can even call their existing or past clients and ask them about how their system is performing under the potential company’s care. Find out how the technicians respond to emergencies and do they clean the area after completing the task.
A quality HVAC Company will respond 24/7 and have adequate technicians to respond in awful weather, when calls pile up.
For new HVAC installation
For suggesting a new HVAC system the technician will size a unit to match your house and existing ductworks. The contractor will also consider heat-loss calculation to decide the unit size.
Oversize unit can pile up your energy sizes, so energy upgrades will be suggested. For example, an extra insulation layer in the attic can allow investing in a small HVAC unit.
Other variables the technician will apply in his calculations are your regional cooling and heating load, capacity of unit you are taking into consideration and cost of different kinds of energy (gas, oil and electric).
