Preventive Maintenance

Why do I need Maintenance?

Think of preventive maintenance in the same way as maintenance for your car: If you don’t change your engine oil and replace belts and filters, the engine will lock up and the vehicle won’t operate. The same holds true, in a sense, for HVAC systems. If you keep your system properly serviced, it will last longer and run at peak performance, keep your utility bills low and provide peace of mind. If you have a furnace and it’s a gas fired appliance, it should be checked every year for safety reasons.

How much does it cost?

Maintenance isn’t expensive compared to what you might spend if your system degrades (and ultimately fails). Proper maintenance costs a lot less over the life of equipment than to change out equipment on a more frequent basis. By keeping up regular service, you can find potential problems before they become large, pricey repairs. Plus, a clean unit operates more efficiently, which means lower energy bills.

The installers were the most conscientious and professional workmen we have had in our home. No detail was over-looked or glossed over. The salesman was personable and knowledgeable and very low-key. The entire experience was positive and we feel, we got more than our money’s worth. Have already recommended them to others. Outstanding Company!
