Time to Replace Your HVAC System

gas furnaceRegular maintenance of the heating and cooling system can lengthen its lifespan. However, wear and tear are inevitable that replacing your HVAC system becomes necessary. We have listed below the signs that indicate the system needs a replacement.

Clues It’s Time to Replace Your HVAC System

Age of the HVAC System

An air conditioner or heat pump that is more than 10 years old and a more than 15-year-old furnace or boiler are indications that the system needs a replacement. When looking for a new unit, look for the Energy Star label. HVAC Systems with Energy Star label are highly efficient, saving you up to 20% on energy costs. Call a professional HVAC contractor to have the new system installed.

Recurrent Repairs

An HVAC system that requires recurrent repairs results in higher energy bills. The unit is also becoming more inefficient.

Irregular Room Temperature

The temperature in some rooms becomes extreme. Too cold or too hot temperatures in some rooms are telltale signs that the system is not working properly brought by inadequate insulation and duct problems.

Absence of a Programmable Thermostat

Your home is either too cold or too hot when you arrive. If no one is left at home, a programmable thermostat will allow you to set the right temperature to make your home comfortable when you arrive.

Humidity Issues

Poor system operation, leaky ductwork, and inadequate equipment lead to humidity problems.

Dust Accumulation

If your home is accumulating too much dust, it could be that the HVAC system has leaky ducts. Leaky ducts can draw air and particles from crawl spaces, attics, and basements and scatter them all over your home. Sealing the ducts can solve this problem.

Noisy HVAC System

If your unit is becoming too noisy, it is an indication of indoor coil problems and a small duct system.

Below 5 Energy Yardstick Score

A home energy yardstick score of below 5 indicates that you have an above average energy usage that leads to higher energy bills.

Questions to Ask the HVAC Contractor

It is important to ask the correct questions before purchasing a new system. Here are some questions that will help you evaluate if you found the right HVAC system for you.

  • What size HVAC system is appropriate? If you have room additions, matching the specifications of your current system may not be a good option.
  • Do you need multiple cooling and heating zones? A reliable and professional HVAC contractor should be able to help you choose the appropriate system that will give you better comfort and energy savings.
  • What are your best alternatives? The contractor should be able to give you efficient alternatives, such as radiant heat systems, heat pumps, and forced-air heating and cooling systems.
  • Should you address humidity problems in your home with either a humidifier or a home dehumidifier?
  • Does the contractor have any special offers or rebates?
  • Will you be getting a tax credit with the new system?
  • What is the efficiency level of the new system? Aside from the lifetime operating costs, you should also consider operating costs when making a decision.
  • What are the filter types they offer? Filter types vary from washable and disposable, with some capable of improving indoor air quality, like HEPA filters, that protect the family’s health.
  • What service plan do they offer to protect and maintain your system?

Replacing your HVAC system does not merely start from buying a new system or installing it at home. It requires a reliable HVAC contractor and having honest communication.

Do You Need to Replace Your Gas Furnace?

gas furnaceA frosty house is an unwelcome situation. The best thing to do when this happens is to check and assess your gas furnace before it fails. Do not wait when a problem comes up or when you have freezing indoor temperatures. It might be time to replace your gas furnace.

Checking Your Gas Furnace

  • Know the Age of Your Unit. Your gas furnace may have been there before you moved in and as old as the house. Look for the manual or call the manufacturer by giving the furnace’s model number.
  • Lifespan. The average lifespan of modern furnaces is 20 to 30 years. If the unit is more than 15 years old and not working properly, then consider replacing it.
  • Energy Efficiency. Compared to an ordinary or traditional gas furnace, a new Energy Star-qualified gas furnace is usually 15% more efficient and is 4% more efficient than a standard model. This is according to the U.S. Energy Star program. The Environmental Protection Agency added that a new Energy Star gas furnace would save every homeowner an average of $91 in energy costs each year.
  • Watch Out for these Signs of Gas Furnace problems as listed below.


Signs of Gas Furnace Problems

  • 1) Higher energy bills even if usage stays the same.
  • 2) Uneven heating in your house.
  • 3) Your furnace is cycling on and off more often than in the previous years.
  • 4) Humidity problems in your home.
  • 5) Excessive noise or your furnace develops buzzes, rattles, or hums.
  • 6) Excessive dust, dirt, soot, or rust particles.
  • 7) Visible signs of rust in and around your gas furnace.
  • 8) Any signs of cracks or corrosion in its components.

Call your local HVAC expert to inspect your home furnace once you see these signs on your unit. Your furnace may need just a simple repair or may require adding a new thermostat or changing the filter.

Know the AFUE Rating. AFUE (annual fuel utilization efficiency) is a rating to measures a furnace’s operating efficiency. An AFUE of below 8% means you need to replace your furnace with a more efficient unit. The new gas furnaces are commonly ranked by efficiency. The ultra-high-efficiency gas furnaces have up to 97% efficiency. These models have variable-speed controls and fans. The high-efficiency furnaces have a 90% efficiency while the mid-efficiency furnaces have an 80% efficiency.

It is better to have more information so you will feel more confident when you replace your gas furnace. Calling a professional and qualified HVAC provider will help evaluate your furnace and save you on costs.

Save Energy with a Remote Programmable Thermostat

Programmable Thermostat

A remote programmable thermostat will help resolve your high energy bills. The heating and cooling systems in a home consume a huge amount of energy, which results in higher utility bills. Is there a possible way to reduce energy bills without sacrificing the heating and cooling in your home?

How a Programmable Thermostat Works

Programmable thermostats are devices that allow you to regulate the temperature of your home based on different settings for different times of the day. They help reduce energy bills by ensuring that your heating and cooling system is set high only in those times of the day that it is needed.  

The total amount of savings on your energy bills will depend on how you use the programmable thermostat. Adjusting the normal setting of your thermostat by 7-10 degrees for 8 hours/day will give you an average saving of around 10% per year.  

You can store several daily settings on the thermostat like 7 or more temperature settings per day. You can even cancel it manually without disturbing the daily or weekly programmed settings.

With a thermostat, you can decrease the temperature during winter and increase it during summer. By doing this, the heating and cooling system work less, which means lower energy costs.

To maximize your savings when using a thermostat:

  • Set the thermostat to remain at its energy-savings level for up to 8 hours per day
  • Adjust its settings if you will be away from home or go on a holiday for several days. A number of thermostats have a “hold” or vacation mode for this purpose.
  • Install a thermostat in every delineated area to maximize comfort and savings if you have a zoned heating or cooling system.
  • Observe proper maintenance by changing the batteries every year or when indicated.
  • Adjust the settings to increase your savings and comfort. Remember that you save around 2% on your electric bills for every one-degree adjustment.


Install a programmable thermostat at your home now and lower your energy bills without sacrificing the comfort of your home. Not only will it save you on energy costs, it will also make your home sustainable.

American Air Heating & Cooling can also install a wi-fi thermostat to give you the ultimate control for comfort in your home. With a wi-fi thermostat you will be able to control and program the settings using a smart phone, tablet or computer.
