Q:  Why should I maintain my HVAC system?

A: Even if your heating & air conditioning system was built to go the distance, it’s got to be maintained to stay in good condition.   A properly maintained system will last longer with fewer breakdowns and save money every month with lower fuel bills.  Preventive maintenance for your heating and cooling systems is much like the regular maintenance you do for your car by changing the oil and filters and remember the cost of maintenace is much less than the cost to replace it!  Click on our Preventive Maintenance for more information.

Q: How long does a typical gas furnace or air conditioner last?

A: The average life of a gas furnace is 15 years. The average life of an air conditioner is 12 years. Regular maintenance helps prolong the life of heating and air conditioning systems.

Q: When should I replace my furnace or air conditioner?

A: If you need a repair and your system is approaching the average life span you could be better off replacing the system with new high efficiency equipment.  We can help you weigh the costs and benefits looking at rebates available, estimated fuel savings, future repairs and added comfort a new system could provide.

Q. What’s the difference between a boiler and furnace?

A: A boiler uses oil, gas or electricity to generate hot water and in some cases steam, which is piped to baseboard radiation systems on the perimeter of the house. A furnace burns oil or gas to heat up air which is forced by a fan through a large ducted system and blown through registers in various parts of the house. Generally speaking, a cast iron boiler for a baseboard system has more than twice the life expectancy of a furnace for a hot air system.

Q: My pilot light is on, but my furnace is not operating – what should I do?

A: First, check for power, check fuses and/or ON-OFF switch. Next, check thermostat for proper setting. If none of these approaches work call a certified service technician.

Q: Why is my furnace so noisy?

A: It could be a worn fan belt, bad bearings or bearings in need of lubrication.  All of these issues are checked in a Preventive Maintenace service.

Q: My allergies seem to bother me alot at home. What can I do?

A: First change your air filters to make sure they are doing their job.  If allergies remain a problem consider the many add on options available including whole house filtration, air purifiers, humidifiers and ERV’s.  You might also consider having your air ducts cleaned. Much of the dust, mites and other debris that build up in the air ducts are circulated into the air of your home.  Contact us and we can help you find the right solution.

Q: What are the benefits of an air filtration system?

A: An Air Filtration system removes bacteria, dust, dust mites, pet dander, pollen, smoke, spores and more. It can also reduce the cost of Furnace and Air Conditioner maintenance.  Today many options are available, contact us for more information.
