Should I Repair or Replace My HVAC System?

The average lifespan of an HVAC system is about 15 to 20 years. The key to having a long lifespan for your HVAC is regular professional maintenance. You'll also need a few tune-ups and repairs along the way. But how can you tell when your HVAC's time is done? Here are the factors to consider when you're deciding whether to repair or replace your HVAC system. 

1. Age of system - If your HVAC system is within the normal lifespan or just even 10 years old or more, you might benefit from a newer, more efficient system. 
2. Cost of repairs - If the repair cost is 30% or more of the cost of a new system, it's worth considering if a new system is right for you. 
3. Inefficient heating and cooling - If your system is struggling to heat and cool your home efficiently and maintain the set temperature, you might be better off investing in a new HVAC system. HVAC systems lose efficiency with age and wear and tear. 
4. Dust is accumulating in your home - If you've noticed more dust accumulating than usual, the ventilation and humidity control of your HVAC system could be breaking down. 
5. Energy bills increasing - Aside from a rate hike, your utility bills should follow a consistent pattern throughout the year. If you notice your bill is steadily increasing, especially when it normally goes down, it could be a sign that you need to replace your HVAC system. As mentioned, HVAC systems lose efficiency over time. A system with declining efficiency uses more energy and costs you more on your utility bill. 
6. Frequency of repairs - If your HVAC system is breaking down and needing repairs frequently, you might be better off replacing the system rather than spending more money on more repairs. 
7. Carbon monoxide leak - If your HVAC system is leaking carbon monoxide, you and your family are not safe using the unit. If the leak can't be found and repaired, it's time to put safety first and get a new system. 
There are a number of factors to consider when deciding whether to repair or replace your HVAC system. If your system is young and you've kept up with regular maintenance, you would do well to repair. If your system is older and breaking down frequently, you would do well to invest in a new system instead of more repairs. Still not sure? Call Carolina Comfort Systems!

How Do Geothermal Systems Work?

Geothermal systems harness heat from the earth during the winter to heat your home and disperse heat back to the earth during the summer to cool your home. Also known as geoexchange systems, geothermal systems are a clean, renewable energy technology. 

 With geothermal systems, pipes are installed deep underground (typically called loops) and filled with a water-based solution. This solution aids in the process of absorbing or dispersing heat to and from the earth surrounding the pipes. That heated or cooled solution is then routed to a heat pump above ground that processes the heat or cooling from the water to air that can then be circulated into your home. 
So a basic example for heat would be: 
1. The earth absorbs heat from the sun. 
2. The water solution in the pipes absorbs heat through the pipes from the earth. 
3. The water goes through an above ground heat pump. 
4. The heat pump sends heated air through to your home. 
 Geothermal Facts

 Here are some facts you should know about geothermal systems.

 Geothermal systems work almost anywhere in the world. In fact, Iceland is the world's top producer of geothermal energy.

  • Geothermal systems can also be used to heat water for your home, saving you as much as 50% on your water heating costs - or more.
  • Geothermal systems are four times more efficient than a traditional HVAC system.
  • The average lifespan of a geothermal system is 25 to 30 years.
  • With the reduction in heating and cooling costs, a geothermal system typically pays for itself within five to 10 years.

Curious about whether a geothermal system might be right for you? Call Carolina Comfort Systems! We can help you evaluate your property to see if a geothermal system would work for you and we can help you explore the costs of the system and the savings you can expect on your utility bills.
