Replacing key home systems like your heater, air conditioner, or plumbing is a big decision. Aside from being a significant financial investment, knowing when to replace older equipment with modern, energy-efficient options requires a careful and professional assessment. Yellow Dot Heating & Air Conditioning helps Raleigh homeowners make informed choices; when you spot any of these signs, make sure you get in touch!
Four Signs Your HVAC Needs To Be Replaced
If your heating and cooling system is outside its manufacturer’s warranty, you’ll have to decide if an HVAC repair or replacement project is your next step, based on several factors.

1. Your Equipment Is More Than a Decade Old
Older equipment is often harder to repair, especially when replacement parts aren’t readily available. Most systems become less energy-efficient due to years of use; your Yellow Dot Heating & Air Conditioning technician can help you determine whether it is worth repairing HVAC equipment more than 10 years old.
How Long Do HVAC Systems Last?
The expected lifespan of HVAC equipment varies for several reasons. Electric heating systems tend to last the longest, at roughly 20 years, with natural gas furnaces and heat pumps averaging 10-15 years of reliable use.
2. You’re Dealing With Frequent Repairs
We appreciate our loyal customers, but if your equipment is breaking down multiple times a year, it may be time to consider upgrading to an energy-efficient heat pump or modern equipment. Generally, you should replace your HVAC system when repair costs exceed 50% of the price of new equipment. This approach can often be the most cost-effective option.
3. Your Utility Bills Are Going Up
Older HVAC systems become less efficient as they age. This can lead to more repairs and higher gas or electricity bills. A new system can save you money over time by working more efficiently.
4. Your HVAC System Is Loud and Underperforming
If you’re experiencing loud sounds, rattling, or foul smells from your HVAC system, it might be time for an upgrade. Look for uneven temperatures throughout your home or weak airflow; these are additional signs that you need to upgrade your HVAC.

Three Signs You Need To Replace Your Plumbing
As you’d expect, age, water quality, and leaks are the biggest factors in determining when to replace your home’s core plumbing infrastructure. For plumbing repair or replacement services in Raleigh or nearby communities, schedule an appointment with us. Our team will take a closer look and explain all your options!

1. Your Home Is Over 50 Years Old
Old, outdated pipes are more likely to have mineral and rust buildup or be structurally compromised by corrosion. If your home was built before the 1970s, there’s a good chance it has galvanized steel or polybutylene pipes. Both of these materials are known to deteriorate and burst, causing leaks and potentially serious water damage.
How Long Does Plumbing Last?
The expected lifespan of plumbing varies depending on the age of the pipes, soil composition, climate, and water content. Hard water sometimes causes mineral buildup faster in galvanized steel and other materials. If you’re wondering when your home's plumbing was last updated, ask our team for a thorough assessment of your system.
How Long Does Copper Plumbing Last?
Copper is durable and long-lasting, with most copper piping lasting 50-70 years.
How Long Does PEX Plumbing Last?
PEX, short for cross-linked polyethylene (PEX), is usually good for 40-50 years, although some products are rated for much longer.
To find out when your plumbing was updated last, look at any home maintenance records, check with city or county permit records, or schedule an appointment so we can provide an accurate estimate.
2. You Have Constant Leaks and Water Pressure Issues
The occasional leak is almost unavoidable, but recurring leaks in different parts of your home are a cause for concern. Leaks throughout your piping system indicate high levels of corrosion, increasing the risk of burst pipes.
3. Discolored and Smelly Water
Discoloration, foul smells, and unpleasant taste are all signs that your pipes are corroded. Look for rusty, brownish water, the smell of sulfur, or other odors that are caused by sewer line issues or other sources of contamination.
Questions To Ask When Replacing Whole-House Plumbing
Replacing your plumbing is a significant investment, so take the time to learn as much as possible about your plumbing.
Ask your plumbing professional:
- What materials do you recommend for new piping, and why?
- Are you licensed and insured?
- How long will the project take?
- Will you handle any necessary permitting?
- Is there a warranty for your work?
Our plumbers are always prepared to answer these questions, and many others. Our commitment to communication and education empowers homeowners to understand their property inside and out.
