Frequently Asked Questions & HVAC Glossary
Cooling System
Upgrade to a high-efficiency air conditioner – Replacing your old, inefficient air conditioning system with a high-efficient one can cut electricity bills significantly. Consult one of our professional technicians to ensure your system is the right size for your home, and you are not over- or under-cooling for your space needs.
Turn up the temperature – To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
Install ceiling fans – Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction as a way of creating a nice, gentle wind.
Have an annual maintenance performed – Having an annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
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 will not be spending money cooling rooms that are used less.
Heating System
Upgrade to a high-efficiency furnace – New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 percent of your home-heating costs in one year, and within a few years, you will have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy efficient motor can save 20 to 50 percent of the energy needed to continuously operate a fan motor. Let us show you the advantages of replacing your old furnace today.
Have an annual maintenance performed – Having an annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
Install a programmable thermostat – A programmable thermostat enables you to control your home’s temperature when you are away or asleep. For every one degree you lower your thermostat for seven hours per day, you save one percent on your heating bill.
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 furnace can operate efficiently and there is even heat distribution.
Close vents in less-used rooms – By closing the vents, you will not be spending money heating rooms that are used less.
Install ceiling fans- Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.
The best way to find a reputable HVAC contractor is to ask your friends, family and neighbors whom they use.
Find a contractor who has been around a while. The failure rate in HVAC is around 20% per year. That means that one out of five will not be doing business next year. The failure rate drops off for HVAC companies that have been around for 4 years. Sleeping Giant has been in business since 1963.
You want to make sure any company you do business with is properly licensed and insured, and it is always a good idea to check out a company’s rating with the local Better Business Bureau. Aditionally, many equipment manufacturers list their dealer’s customer satisfaction ratings on thier dealer locator section of their websites. Check out our satisfaction rating with American Standard.
A unit that is too big for your home will have short run cycles. It may take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems.
These short run cycles also mean your system starts and stops more often which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long run cycles.
The same holds true with heating systems. An oversized furnace will warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.
Check the settings on your thermostat. Make sure the temperature control selector is set below the current room temperature, and the system switch is on the COOL or AUTO position. The fan switch should be set to ON for continuous airflow or AUTO if you want the blower to operate only while the air conditioner/heat pump is operating.
Try to get the air conditioner/heat pump to turn on by lowering the thermostat to its lowest temperature setting.
If the air flow out of your registers seems low, check the air filter. An extremely dirty air filter can block air flow.
Make sure all registers are open and not obstructed.
Check the power disconnect switch by each unit (outdoor and indoor).
Check the fuse/breaker at the electrical panel for both the outdoor and indoor unit.
If the problem persists, please contact us.

Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.
Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.
Your heating and cooling system is just like your car and needs regular maintenance. Our service agreement is priced at break-even cost so all of our clients can afford to maintain their systems. Servicing your system will increase the lifespan of your system, reduce energy costs and increase comfort.
Variable speed compressors work in much the same way, but instead of two possible stages they can automatically make constant and minute adjustments to avoid temperature swings on your home. Variable speed compressors can run from 20-100% capacity (and anything in between) to provide the exact amount of cooling or heating your home needs at any given time.
Finally, a variable speed compressor has the ability to ramp all the way down to around 20%-40% capacity depending on the make and model. These are incredibly efficient and come standard for most of our ductless split systems.
As a result, the production of R-22 refrigerant has decreased steadily since that time, and the prices for R-22 refrigerant have skyrocketed. At Sleeping Giant, we have been installing R410-a systems long before the government made the change. If you have a R22 system that is leaking freon, a new more energy efficicent system that runs on R-410a refrigerant is the right choice for the environment, and your pocketbook.
When you become a customer of the Sleeping Giant maintenance plan, rest assured that one of the things we will check is the heat exchanger, flue exhaust pipe and other components of your gas heating system to make sure carbon monoxide is not seeping into your home environment from your heating system.
If you smell propane (LP) gas:
Exit your home immediately.
Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
From a safe area, contact your propane supplier and call 911.
If you are able, shut the propane gas supply off at the tank.
Stay away from your home until you have been told that it is safe to return.
Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor. If you smell gas faintly, check all areas of your house for strong odor. If the smell is only faint throughout all areas of your home, call your heating contractor to get it fixed within 24 hours. Keep the house well ventilated by opening windows.
If you smell a strong, persistent odor:
Exit your home immediately.
Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
From a safe area, contact your gas company or call 911.
