Steps In the Furnace Replacement Process
Replacing or installing a furnace is a significant task that requires careful planning and professional attention to ensure safety and efficiency. At Chesterfield Service, we simplify this process for our clients with a structured approach.
Our furnace installation process involves:
- Initial consultation and assessment: Our process begins with a thorough assessment of your current heating system and an in-depth consultation to understand your needs and budget. This helps us recommend the most suitable furnace for your home.
- Choosing the right furnace: Based on the assessment, we help you select a furnace that best meets your home's heating requirements. We consider factors such as the size of your home, energy efficiency ratings, and your preferred brand.
- Preparation for installation: Before the installation, we ensure all necessary preparations are complete. This includes examining your existing ductwork, verifying that it’s in good condition, and addressing any modifications needed for the new furnace.
- Installation: Our certified technicians manage the entire installation process so that your new furnace is installed correctly and safely. This involves meticulous attention to detail, from connecting the unit to your home’s systems to promoting proper ventilation.
- Post-installation testing: After installation, we conduct comprehensive testing to ensure your new furnace operates efficiently and safely. We adjust settings and check for any issues that might affect performance.
- Customer orientation and maintenance guidance: Finally, we provide guidance on operating your new system and offer tips on maintenance to maximize your furnace's lifespan and efficiency. We also discuss service agreements for ongoing support.
Following this detailed process helps your new furnace provide optimal comfort and reliability for years to come.
Signs That You Need a New Furnace
When you notice your furnace is underperforming or causing issues, it’s important to call a professional HVAC company like Chesterfield Service to inspect and diagnose the issues with your system. Our technicians can let you know what’s wrong with your furnace and how much longer you can expect to use it.
Call us when you notice warning signs like:
- Your furnace is getting old: Most furnaces have a life span of 15 to 20 years, but when your furnace is over ten years old, warranties start expiring, and repairs become more expensive. If you can't find any documents or service records, a professional HVAC technician can tell you the age of your furnace.
- Repairs are becoming too costly and frequent: While furnaces could need a simple repair here and there, you may want to invest in an upgrade instead if you’re continuing to spend money on fixing your aging system. Generally, if the cost to repair your furnace is 50% or more of the price of a new furnace, it’s best to replace it.
- Your heating and energy bills are going up: Although you may have a functioning furnace for another few years, those last few years of its service life are likely to be far less efficient than that of a newer model. With a low-efficiency furnace, your heating and energy expenses may be increasing year by year. A newer, more energy-efficient furnace could help provide savings on these bills.
- Strange odors: Since furnaces rely on gas for heating, you should be wary of any strange smells coming from them. If your furnace is leaking gas, turn it off right away and call Chesterfield Service emergency service. It’s not safe to continue to run a leaking furnace, and this is a clear sign that you’ll need to have a new furnace installed right away.
- Comfort issues: When your system doesn’t keep you comfortable throughout your entire house, it’s a sign of serious problems. It could be leaks in your air ducts, a dirty air filter, or your furnace struggling to keep up with your heating needs.
