When is it time to replace my heating and cooling system?

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.


What determines the SIZE of air conditioner I need? 1 Ton? 2 Ton?

When Arizona temperatures soar, choosing the right size cooling unit will help you keep your living space cool economically and efficiently. Studies show that over half of home heat pumps and air conditioners are oversized – often 60 to 80 percent larger than they need to be! Although a larger cooling unit may seem like a good idea, oversized cooling units cost more to buy and operate and actually don’t do as good a job of keeping you comfortable year-round as a properly sized unit.

Why Do I Need Preventive Maintenance Tune-ups On My Air Conditioning and Heating System?

First, let me answer your question with a question… Would you buy a new car and never bother to change the oil? Of course not! You want to protect your investment and you know regular maintenance will not only extend the life of your car, it will ensure you get the best gas mileage possible.

Your air conditioning system requires routine maintenance for the exact same reasons; protecting your investment, extending the lifespan of your equipment, and ensuring the lowest possible energy bills!

Research continues to show routine maintenance on heating and cooling equipment ensures system efficiency (lowest energy bills), and prolongs the life of the equipment. To learn more about this, and our Residential Comfort Club, click here.


Do I really need routine maintenance on my heating and cooling equipment? Why can’t I just wait until my equipment fails before I call for service?

Your heating and cooling equipment is a major financial investment. Protect that investment! You already know from experience that preventive maintenance on your vehicle extends the life of your car, as well as ensures you get the best gas mileage. This is also true of your heating and cooling equipment. Temco recommends 2 service visits per year to ensure your equipment runs as efficiently (lowest energy cost) and effectively (highest comfort level) as possible.
