With the proper attention, heating and cooling systems can keep you comfortable year-round. Heat pumps and oil-fired furnaces and boilers need a yearly professional tune-up. Gas-fired equipment, on the other hand, burns cleaner and can be serviced every other year. A close inspection will uncover leaks, soot, rust, rot, corroded electrical contacts and frayed wires. In furnace (forced-air) and boiler (hot-water) systems, the inspection should also cover the chimney, ductwork or pipes, dampers or valves, blower or pump, registers or radiators, the fuel line and the gas meter or oil tank — as well as every part of the furnace or boiler itself.

Next, the system should be run through a full heating cycle to ensure that it has plenty of combustion air and chimney draft. Finally, cleaning the burner and heat exchanger to remove soot and other gunk will prevent such buildup from impeding smooth operation. For the burner, efficiency hinges on adjusting the flame to the right size and color, adjusting the flow of gas or changing the fuel filter in an oil-fired system. A check of the heat pump should include an inspection of the compressor, fan, indoor and outdoor coils and refrigerant lines. Indoor and outdoor coils should be cleaned, and the refrigerant pressure should be checked.

It is not possible to give a precise answer, since central air conditioning systems use condenser and evaporator units separated by variable lengths of tubing, depending on the particulars of an installation.

Most units hold 4 to 6 lbs. of refrigerant, depending on the cooling capacity (2 ton to 4 ton). Check the data plate on condenser it will tell you the exact ounces it holds. Then you must adjust the charge up from what the nameplate says to compensate for the piping between the two components of the unit.

The evaporator may be dirty or the condenser (outside unit) may be dirty. You may be low on "freon", indicates a possible leak. Check the filter.

Yes, programmable thermostats can reduce the energy used for air conditioning or heating by 5 to 30%. Programmable thermostats save money by turning the air conditioner to a higher setting (or heater to a lower setting) when no one is present in the house, or in the evenings when it is cooler.

You would have to know the following: cfm (cubic foot per minute) requirements of the system (for example, a 3 ton system requires 1200 cfm). Next you would have to calculate what the size the opening would be (another example, 1200 cfm requires an opening that is 16" x 12"). If you block off too much return air (or supply, for that matter) you can cause serious problems on the cooling side, and potentially unsafe conditions on the heating side.

Yes and in a big way. If you have an old machine built in the 70's it was probably rated around 6 SEER when it was new and now is running something like 3 or 4 SEER. Replace it with a new 13 SEER unit and cut your cooling energy bill by 67% or more! The indoor coil must also be replaced at the same time in order to get the advertised SEER rating of the new unit and the rest of the system must be in proper working order.

It is impossible to quote a price without first checking conditions at the job site. We simply cannot determine what the price will be without this first step. Price will be influenced by the size, SEER rating, and location of the new unit as well as whether or not the existing furnace, electrical panel, and ducts are suitable for air conditioning or if they must be replaced. We don't charge anything to come out to your house and give you a written proposal, customized especially for your situation, showing you your prices and your various choices. In almost all cases the proposal is written up for you on the spot with no waiting to receive it in the mail.

Yes. We suggest that if you have a combination heating and cooling system you have us come out and do a tune up on the system every six months. Keeping the system clean is the name of the game. As the coils and blower wheels begin to get dirty the efficiency of the system plummets, your energy bill climbs, and your comfort level drops. Regular tune ups also extend equipment life and help to prevent mechanical break downs.

A heat pump is a HVAC compressor that cools outside and heats inside. The unit has a reversing valve that changes the direction of the freon flow. It is cheaper to operate than a resistive heating circuit alone. It will work efficiently until the temperature drops below 38 degrees. When the temperature drops below the magic number, the restive heat is more effective. In theory the heat pump will work at 32 degrees, but the heat produced is very little.

As we heat our homes, the air has a tendency to dry out. This dry air can damage the woodwork and furniture you have in your home as well as zap the moisture from your skin. Dry air even makes you feel cooler because your body senses heat as a combination of temperature and humidity. Adding humidity to offset this drying process will improve your comfort as well as preserve the woodwork in your home. As an added benefit, you may actually be able to lower your thermostat a couple of degrees. You will not only feel warmer but you may actually lower your heating bill!

Adding this much needed moisture will make your home a healthier and more comfortable place to spend your time. Contact us and we will be happy to discuss your choices and provide you with pricing for adding a humidifier to your home.

It's a fact: the trapped air we breathe in our homes can be loaded with dust, pollen, plant spores, and other pollutant particles. In many cases, it's worse than the air outside.

If your furnace has a standard (replaceable) filter, change it once a month. If you have an electronic cleaner, clean it every three months. If you have a whole house HEPA cleaner, you need to replace it once a year.

Cleaning your ducts may be beneficial in improving your indoor air quality. A premium whole-house duct cleaning will help decrease the spread of contaminates in your ductwork and home. New construction homes can benefit from having the ductwork cleaned to remove drywall dust, sawdust and other debris from the construction process.

UV is the abbreviation for ultraviolet. Located in the return air ductwork and by the indoor cooling coil, the ultraviolet air treatment system continuously emits high – intensity ultraviolet (UV) energy. The energy eliminates (kills) a very high percentage of airborne bacteria and germs passing over the UV light field inside the ductwork. The UV light mounted next to the indoor cooling coil will help eliminate the growth of mold, mildew and other contaminates from the drain pan and coil surface

An air conditioner transfers heat from the inside of a building (where it is not wanted) to the outside. Refrigerant in the system absorbs the excess heat and is pumped through a closed system of piping to an outside coil. A fan blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air. Because the heat is removed from the indoor air, the indoor area is cooled.

Puron is a new generation of refrigerant that does not contain chlorine. The EPA states that chlorine is the chemical responsible for destruction of the Ozone layer of our atmosphere. Although Puron is non Ozone depleting it is still considered a greenhouse gas and should only be handled by an EPA certified technician.

According to the Energy Star experts, certain telltale signs indicate it’s time to consider replacing heating and cooling equipment, or improving the performance of your overall system. It may be time to call a professional contractor to help you make a change if:

Your heat pump or air conditioner is more than 10 years old.

Consider replacing it with a unit that has earned the ENERGY STAR label. Installed correctly, these high-efficiency units can save up to 20 percent on heating and cooling costs.

Your furnace or boiler is more than 15 years old.

Consider replacing with an ENERGY STAR qualified furnace, which is 15% more efficient than a conventional furnace. If you have a boiler, consider replacing with an ENERGY STAR qualified boiler that is 5% more efficient than a new, standard model.

Your equipment needs frequent repairs and your energy bills are going up.

Your cooling or heating equipment my have become less efficient.

Some rooms in your home are too hot or too cold.

Improper equipment operation, duct problems or inadequate insulation could be the cause.

No one is home for long periods of the day and you do not have a programmable thermostat.

Install a programmable thermostat or have a good contractor install one and instruct you on its use — to start saving energy and money while they’re away or sleeping.

Your home has humidity problems.

Poor equipment operation, inadequate equipment, and leaky ductwork can cause the air to be too dry in the winter or too humid in the summer.

Your home has excessive dust.

Leaky ducts can pull particles and air from attics, crawl spaces and basements and distribute them throughout your house. Sealing your ducts may be a solution.

Your heating or cooling system is noisy.

You could have an undersized duct system or a problem with the indoor coil of your cooling equipment.

R-410A is the refrigerant of choice to replace Freon (R-22). It is environmentally friendly and cools equally to R-22. You may have heard it called PURON

Spray it with Fantastic or 409 cleaner, let it dry and reinstall it. Or put it in your dishwasher. Use a soap that leaves no film and be sure to protect the thin "piano" type of wires in the cleaner from the spikes in the dishwasher tray. One way is to set the cleaner on top of glasses that are placed over these spikes in the dishwasher.
