Frequent leaks, an AC that won’t blow cool air, and constant equipment failures can be incredibly frustrating. For many Decatur homeowners, however, it’s not always clear whether repairing or replacing an outdated HVAC system or old plumbing is the right move. The experienced technicians at Valley Heating & Cooling offer their insights on when to replace plumbing, heating, or cooling equipment, plus common signs it’s time to upgrade.
Four Signs You Need To Replace Your HVAC Equipment
If your heating and cooling system is outside its manufacturer’s warranty, you’ll have to decide if an HVAC repair or replace project is your next step, based on several factors.

1. It’s Over 10 Years Old
Older equipment is often harder to repair, especially if replacement parts aren’t readily available. Most systems become less energy-efficient due to years of use; your Valley Heating & Cooling technician can help you determine whether it is worth repairing HVAC equipment more than 10 years old.
How Long Do HVAC Systems Last?
Most HVAC systems last 10-15 years, with electric heating systems and heaters lasting around 20 years. Many factors influence how long your AC or heater will last, including how regularly it is serviced and how often it is used. Knowing your system’s age will help you decide whether to replace or repair an HVAC system.
2. It Needs Constant Repairs
While we appreciate our regular customers, repeated visits for HVAC repairs may indicate it's time to consider upgrading to a heat pump or more modern equipment. Recurring minor maintenance or major fixes can add up; if the cost of a repair is greater than 50% of a new system, replacement is likely the best option for equipment 10 years or older.
3. You’re Paying More for Electricity or Natural Gas
Older HVAC equipment is less efficient as it ages. Not only can this result in more frequent repairs, but it also causes your gas or electricity bills to increase. A new system might pay for itself over time by substantially improving efficiency.
4. Your HVAC System Is Loud and Underperforming
If you hear loud sounds, rattling, or smell foul odors from your HVAC system, it may need an upgrade. Other signs include uneven temperatures and weak airflow.
When Is the Best Time To Replace Your HVAC System?
The best time to replace your HVAC system is during the off-season. In Decatur, spring and fall are usually our slowest times of the year, which means we can offer more flexible scheduling, faster service, and more competitive pricing.

Three Signs You Need To Replace Your Plumbing
Age, water quality, and leaks are the biggest factors in determining when to replace your home’s core plumbing infrastructure.

1. Your Home Is Over 50 Years Old
Old, outdated pipes are more susceptible to mineral and rust buildup, and they may also be structurally compromised due to corrosion. If your home was built before the 1970s, it likely has galvanized steel or polybutylene pipes. Both types of materials are known to deteriorate and can burst, leading to leaks and potentially serious water damage.
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.
How Long Does Plumbing Last?
Depending on the material, soil composition, water content, and climate, most pipes will last 20-40 years, although the actual lifespan varies widely. The best way to determine the age and condition of your home’s plumbing is to contact an experienced plumbing professional.
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.
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. Your Water Is Discolored … and It Stinks
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.
