How to know if your thermostat is failing
While thermostats rarely fail outright, they can degrade over time as mechanical parts stick or lose their calibration. Older units will send faulty signals if they’ve been knocked out of level or have dirty switches. To recalibrate an older unit, use a wrench to adjust the nut on the back of the mercury switch until it turns the system on and, using a room thermometer, set it to the correct temperature. Modern electronic thermostats, sealed at the factory to keep out dust and grime, rarely need adjusting. However, whether your thermostat is old or young, the hole where the thermostat wire comes through the wall needs to be sealed, or a draft could trick it into thinking the room is warmer or colder than it really is.
How long can I expect a new furnace or air conditioner to last?
If you have a qualified technician perform regular preventative maintenance and service suggested for your unit, industry averages suggest that an air conditioner should last 12-15 years (sea coast applications may be less) and a gas furnace should last as many as 20-25 years.
Should I change my indoor air conditioning coil?
When replacing your air conditioner or heat pump, the answer is most likely yes. The efficiency ratings that are advertised for an air conditioner or heat pump are based on the performance as part of a matched system. If only the outdoor portion is changed, the efficiency and savings could be less than that of a matched system.

How can I reduce my energy costs?
Upgrade to a high-efficiency system - Swapping your old, inefficient air conditioning system for a high-efficiency one can cut electricity bills by up to one-third. Schedule a FREE in-home consultation with one of our HVAC specialists to receive an estimate showing how much you can save by upgrading to a high efficiency system. Get started with some energy saving tips:
• Adjust the temperature - Typically, adjusting temperatures 5–8 degrees (down in winter, up in summer) can help save energy if you're going to be away from home for several hours.
• Install ceiling fans – Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.
• Have annual maintenance performed – Tuning up your cooling system each spring and your heating system each fall will help ensure each operates at peak efficiency and can help you identify and resolve any potential issues before a breakdown occurs. Learn more about HVAC tune-ups
• Don't block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even, cool air distribution.
• Close vents in less-used rooms – By closing the vents, you won't be spending money cooling rooms that are used less.
• Install a programmable thermostat – A programmable thermostat enables you to control your home's temperature when you're away or asleep. For every 1° you lower your thermostat for seven hours per day, you can save approximately one percent on your heating bill.
Can you give me a price without a in-home consultation?
No, we cannot provide a quote over the phone, as pricing varies based on your needs and the unique conditions in your home. In order to properly size your system, a detailed load calculation must be performed by a qualified technician. Installing an oversized or undersized unit may result in higher utility bills and your system may not heat or cool at capacity.
What is a tune-up?
When do I need to have my unit serviced?
My outside air conditioning unit stopped cooling and I checked outside to find ice on the bottom part of the unit. When I turned back on the outside fan kicked in but I am getting no cold air in the house. Is there a reset switch?
My air conditioner isn't running?
Air conditioner turns on and off repeatedly?
