When Is It Time for a New Heater?
If your heater is having problems, you may be wondering whether repair or replacement is the smarter choice. You don't want to replace a system that still has life left in it, but you also don't want to get stuck with constant repair bills and a house that is never warm enough. While every situation is different, certain signs usually indicate that installing a new system will save time and money in the long run.
Here are the most common signs your system may need replacement:
- Heater is 12–15 years old or older
- Repairs are frequent and costly
- Energy bills are rising without more usage
- Inconsistent or weak heating in multiple rooms
- Strange noises, smells, or visible rust
If you are experiencing any of these issues, a new, energy-efficient heating system may be the smarter, more economical choice. Tri-County Air Service offers a full line of Carrier products, known for their durability and performance. We can also provide ductless mini-split installation for those who want a flexible heating solution for a single room or a home without ducts.
How Long Does a Heating Installation Take?
Most heating installations are completed in one day, depending on the type of system and the complexity of your home’s setup. Larger homes or projects that require custom ductwork or electrical upgrades may take a bit longer, but our technicians work efficiently to minimize disruption and ensure your system is ready as soon as possible.
Before installation begins, our team performs a thorough assessment of your home to determine the best unit size and placement for optimal efficiency. Once installation starts, we:
- Remove your old system (if applicable)
- Prepare connections and ductwork
- Install and test the new system for performance and safety
- Walk you through the controls and maintenance tips
In most cases, homeowners can expect their new heating system to be up and running by the end of the day, allowing for immediate comfort. Our goal is to make the process smooth, transparent, and efficient — so you can enjoy reliable warmth without unnecessary delays.
How Can I Maintain My New Heating System?
To keep your system running efficiently:
- Schedule annual tune-ups and inspections
- Replace air filters every 1–3 months
- Keep vents and registers clean
- Monitor thermostat settings for efficiency
Routine maintenance helps extend your system’s lifespan and maintain lower energy costs.
