When is it time to replace my HVAC system?

The average life of an HVAC system varies depending on where you live, and whether or not it receives preventative maintenance. But, on average, an HVAC system will last between 10 and 20 years.

Should I repair or replace my HVAC system?

There a few things that you should consider when choosing to repair your HVAC system or replace it. The first consideration is the upfront cost. As time goes on, the cost to repair an HVAC system will become greater and greater in upfront costs. But, you should also consider that as an HVAC system becomes older, it becomes more and more inefficient, costing you money every single month that you wouldn’t have to pay if you had a more efficient HVAC system. Replacing an older, inefficient system with a newer energy efficient system can save as much as one-third on your monthly energy costs. When looking at repairing an existing HVAC system, consider how much money you will save annually by replacing the entire system.

How often does my HVAC system need to be serviced?

HVAC systems should be serviced every single year. This should be done once in the fall for your furnace, and once in the spring for your air conditioning unit. By having annual preventative maintenance done, you will ensure that your system is working optimally when you need it most. The last time that you want your furnace to go out is in the middle of the night in January.

What can I do to take care of my HVAC system?

Make sure to check your air filters monthly. If it is dirty and prevents the free-flow of air going through it, it is time to replace it. Some higher efficiency filters can go up to 3 months before being replaced, but typically, once per month is the suggested time to replace a filter.

Do I need to replace ductwork?

The ductwork is a critical component of your HVAC system that homeowners often overlook. Experts estimate that as much as 70% of all homes have ductwork that has been installed poorly. When ducts have been installed poorly, through leaky ducts or poorly insulated ducts, the hot and cold air that is being circulated doesn’t go where it needs to. To compensate, HVAC systems need to be run longer to bring your home to the temperature that is right for you. When your ducts are not efficient, you are spending a lot of extra money on both monthly energy bills, as well as an early replacement for your unit itself.

What is the life expectancy of my unit?

Carrier products are very dependable and are among the longest lasting HVAC products available today; however, there are a lot of variables, such as routine maintenance that can affect the life expectancy of your specific Carrier Unit.

Where can I get parts for my Carrier equipment?

As a Carrier dealer, Advanced Environment Solutions is the best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

What are the advantages of a programmable thermostat?

Programmable thermostat’s provide you with the ability to control your home’s temperature throughout the day to help save on your monthly energy bill without having to manually change the temperature! They are also more accurate than a thermostat containing mercury since they are electronic.
