Signs That It Might Be Time To Replace You HVAC Unit

When is it time to replace?

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 Allentown AC Repair companies in order to get an estimate.

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 may 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.

Air conditioner uses R 22 Freon. Freon is being phased out by the federal government in order to conserve energy nationwide. As a result, the costs of Freon are rising exponentially. If your air conditioner uses Freon, you’ll have to replace it eventually in order to switch over to the new refrigerant (R410A). If you’re having major problems with your air conditioner, especially if they involve the need for more Freon, it’s probably a good time to replace your unit.

You might be asking yourself what to replace your unit with. Here are some options:


The window unit is one of the most popular AC systems in the country for a number of reasons such as, being the most affordable units, and the easiest to install. But they usually are not the best choice in terms of efficiency, convenience, and versatility. They are usually much louder than their ductless air conditioner counterpart. They must be positioned in a window which means less natural light and view of outside. Owners of a window unit also assume a security risk with a window air conditioner. Removal of an air conditioning unit could provide an easy unwanted entry into your home.


The ductless mini-split system has a number of advantages:
  • Cost efficiency.
  • Great for renovation work. Because it's a ductless system, the air handler simply gets mounted in where it's appropriate and is connected by a line set to the outside unit.
  • Cost efficiency does not mean that they are not efficient. They have models with SEER ratings between 18 and 26. SEER stands for Seasonal Energy Efficiency Ratio which measures how efficient your AC units are. Higher SEER ratings will use less energy and save homeowners money in the long term. The Department of Energy offers online energy efficiency calculators to help homeowners predict how much money they’ll save on energy costs with equipment carrying different SEER ratings. 
  • Ductless mini-split systems are very quiet and very attractive looking when compared to the loud and unaesthetic window units. 
  • Ductless Systems can be single zone or multi zone. Single zone can provide cooling for one room, while multi zone systems can provide air conditioning from 2-9 rooms.

Some customers who already have central air choose to install a ductless mini-split air conditioner as well in order to use less energy while getting comparable results. And for anyone who wants to skip dealing with the duct work central A/C installation requires, it’s the obvious choice.
