Do I Need a New Central Air Conditioning System?

Central air conditioning systems in Massachusetts can last a long time, but eventually will need replaced. Is your A/C working as efficiently as it used to? Is it running at all? If you are having issues with your central air conditioning system, it is a good time to consider whether you should replace it or repair it.

Do You Need to Replace Your Central A/C?

Here are seven reasons you might want to replace your central A/C:

  • Your current system is 10 years or older. Energy efficiency standards have improved over the past decade. Even a system installed a decade ago will not be as efficient as one purchased today.
  • Your cooling bills keep going up. As an A/C system ages, it can start requiring more energy to do the same job it did when it was first installed. This means your energy bills go up every cooling season.
  • You want to make your home more energy efficient. A brand new, energy efficient central air conditioning system is a greener choice, especially if your old system is highly inefficient.
  • The ductwork in your home was installed when it was built. Ducts installed even 10 years ago are likely to have leaks and gaps. This makes them inefficient and will drive up your costs.
  • You have rooms in your home that never get comfortable. The cool air never seems to reach those rooms. It may be due to a struggling A/C system or major issues in the ductwork.
  • You have high levels of humidity in your home. Air conditioning systems pull humidity out of the air while simultaneously cooling it. If your A/C is not running efficiently, you may be having humidity problems.
  • You may have a malfunctioning thermostat. Older thermostats are not as accurate as they were when they were first installed. The temperature on the thermostat may not be what the temperature of the air is.

Don’t Forget to Spring Clean Your HVAC System

Winter is gone. The warmer winds of spring have arrived. It is the perfect time to get some spring cleaning done. If you are getting your spring to-do list together, don’t forget to spring clean your HVAC system.

Your spring cleaning HVAC list

Use this simple checklist to get your HVAC systems ready:

  • Have a professional do routine maintenance. Your HVAC equipment needs annual maintenance to keep it running efficiently. This helps reduce repair costs and prolongs the life of the system.
  • Check and replace your air filters. This is something you should do every month. However, if your A/C is separate from your heating, you may not have checked the A/C filter since last fall. Now is the time to do it.
  • Make sure the drain hole is not plugged. Under your inside A/C unit, you will find a drain hole where moisture escapes. If that hole gets plugged, it could overflow causing damage to your home.
  • Clear any debris or dirt from around outside units. Dirt, fallen leaves, weeds and trash can clog the airflow going into and out of the unit. It is also important to make sure no plants are growing too close. Airflow is critical for it to run efficiently.
  • Clean vents and registers. It is very easy for dust and other particulates to cling to the fins on vents and registers. You can use a soft cloth or brush to remove any built-up dust. This helps keep air flowing.
  • Have your ductwork cleaned. If you see a shower of dust coming out of your vents when your heating or cooling turns on, you need to have your duct work cleaned. This will help improve indoor air quality year round.

Spring cleaning your HVAC system will only take a short amount of time. However, it is time well spent in making sure it will work as the warmth of summer arrives.

Duct Noises Can Catch You Off Guard, But What Do They Mean?

Are unusual sounds emanating from the duct work hidden behind your home’s air registers? Some duct noises aren’t a cause for concern, while others can point to HVAC system issues that impact comfort, indoor air quality and energy efficiency. Here’s how to tell what some of the most common ductwork noises mean:


air ductsWhen the blower cycles on and pushes air through the ducts, the increase in pressure against the metal can cause a popping noise. This type of sound is completely normal. It’s often more noticeable when ducting is new or just cleaned, since accumulating dust has a muffling effect.


If the ductwork is leaky, escaping air can produce a whistling sound when the blower is running. Having the ducting properly sealed and insulated can stop the noise, and prevent unnecessary energy losses that rob you of up to 30 percent of the equipment’s heating or cooling output.

Banging and Rattling

Loose or disconnected duct sections can bang or rattle when the heating and cooling equipment is operating. Checking all the joints, correcting any poor connections and then sealing the ducts using mastic or metal-backed tape can solve the noise issue and help avert future problems.


Metal ducts expand in response to temperature changes. If enough space wasn’t allowed around the ducts during installation, you may hear a scraping noise when the expanding metal rubs against floor joists or other building components.

Whooshing or Roaring

While it’s normal to hear a low roar or whoosh through the ducts when the air handler is running, a sudden increase in noise volume warns you that airflow has become restricted. If replacing the system’s air filter doesn’t help, contact an HVAC professional to identify the cause before airflow loss issues lead to equipment damage.


If you’re hearing scuttling sounds, rodents may have taken up residence in the ducts. Contact an exterminator to get rid of the infestation, then schedule duct cleaning to remove any contaminants.
