Is Your Heating System Struggling to Keep Up?

If your system struggles to heat your home, it might be more cost-effective to replace it. Look for these signs:

Most systems last 12 to 15 years. If yours is aging, a replacement may offer better performance and efficiency.
If you're calling a technician more often than you'd like, the costs can add up quickly. At some point, replacing the unit can be more cost-effective than constant repairs.
An older system struggling to keep up is going to use more energy and run longer. A new system will save your home significantly on energy costs
Hot and cold spots around your home could indicate airflow issues, aging ductwork, or an furnace system that’s struggling to keep up. An upgrade can help deliver even, consistent comfort.
A properly working HVAC system should help regulate humidity. If your home feels too sticky or too dry, your system may not be operating efficiently or may be undersized for your space.

When deciding to repair or replace your system you should consider the age of the unit, the overall performance, efficiency, and the cost of the repair. A common formula in the HVAC industry is multiplying the age of the system by the cost of repairs and if it exceeds $5,000 to replace it. Homeowner’s should also consider the refrigerant the existing unit uses, as older units use R-22 which is costly and no longer widely available.
We install Central Air Conditioning systems, heat pumps, ductless systems (also known as mini-splits, and geothermal systems.
Classic Aire Care makes comfort affordable and convenient. With our flexible financing options, it’s easy to get the HVAC and solutions you need—whenever you need them. We never want your budget to prevent you from getting the systems and services you need to keep your home running. That’s why we’ve partnered with trustworthy lenders to bring you some of the best HVAC and plumbing financing options available.
Classic Aire Care primary sells Lennox and Bryant systems but carry a variety of brands and models. We educate customers and help them find the the right product for their home.
Our goal is to make the installation process as convenient as possible for homeowners. While we often do installs the next day we will work with you to select the best day for you and your schedule.
We are committed to 100% satisfaction on our installations. If within 365 days of the installation, you are not completely satisfied with its performance we will make any modifications or changes necessary to ensure your complete satisfaction with your system. If you are not satisfied we will remove it and refund 100% of your investment. If you system breaks down during the first year and leaves you without heating or cooling we will repair your system within 24 hours or we will pay you $500 for the inconvenience. If your compressor fails twice in the first 10 years we will install a brand new A/C Unit of equal value at no charge. If your heat exchanger fails within 10 years we will install a brand new furnace at equal value at no charge.
Equipment is registered for warranties and rebates are submitted to the manufacturer and utility company. We include an extended 3 year labor warranty with every system we sell with no Maintenance Plans required. Our install coordinators will schedule necessary inspections with local municipalities. All completed invoices are entered and final paperwork mailed to the homeowner.
