Why Should You MAINTAIN?

Here at D&H we believe maintaining your heating and cooling systems is key to staying comfortable — in your home & with your budget.

Lower Your Energy Bills

Maintenance can help you lower your bills! When your heater is in good shape, it wont have to work as hard to keep your home warm and comfortable.

Extend the Life of Your Furnace

No one wants to have to replace their heating system prematurely. Furnaces that get regular maintenance last much longer than units that do not.

Save Money

With regular furnace tune-ups, you can avoid the need for costly repairs in the future. It is much more cost-effective to prevent problems than to deal with them after the fact.

Stay Comfortable

The purpose of having a furnace in the first place is to help you stay warm and comfortable. With preventative maintenance, your unit will work effectively.
