Common Types of Furnaces We Install
At Swift Brothers, we have extensive experience in installing all types of furnaces. Below are some common types of furnaces we install:
- Gas furnaces are a common choice due to their efficiency, reliability, and ability to provide consistent heat during the colder months, making them an energy-efficient heating option for our region’s mild winters.
- Electric furnaces are a popular option for areas without natural gas access. These systems are affordable to install and easy to maintain. While they may cost more to run, their simple design makes them a practical option for smaller homes and businesses.
- Oil furnaces can be a great choice for rural properties without access to a natural gas line. These systems are known for providing powerful heat, although they also require on-site fuel storage and regular maintenance, especially in our humid environment.
- Propane furnaces are versatile and energy efficient. They perform well in coastal climates and provide fast and dependable heating, making them a great fit for families and businesses seeking a clean-burning fuel option.
What Size Furnace Do I Need?
Choosing a properly sized furnace for your home or business is essential. An undersized furnace may struggle to heat your property, while an oversized furnace may lead to frequent cycling and energy waste.
Furnace size is measured using British Thermal Units (BTUs). Some key factors to consider include the square footage and layout of your property, insulation quality, the amount of windows and doors, ceiling height, occupancy, and usage patterns.
At Swift Brothers, we conduct comprehensive load calculations to determine the appropriate furnace size required to comfortably heat your home or business while keeping energy costs low. Reach out today to get started with a quote!
How Long Does Professional Furnace Installation Take?
The expected timeframe for professional furnace installation can vary depending on the size and scope of the installation, the complexity of the project, and the size of the property. Most furnace installations are completed within 4-8 hours, although projects involving modifications to existing ductwork or electrical systems can take longer.
At Swift Brothers, we strive to complete new installations as quickly as possible without compromising on safety or quality. Our goal is to get your new system up and running while minimizing disruptions to your home or business. Plus, we offer flexible same-day scheduling and weekend appointments for your convenience!
Can I Install My New Furnace Myself?
While it may be tempting to install your new furnace yourself, DIY installation can cost you more money in the long run. Investing in professional installation is a must to protect your safety and keep your furnace running reliably. Some important reasons to work with our certified technicians include:
- Safety. Furnace installation involves complex gas and electrical connections, making proper installation a top priority to prevent gas leaks, carbon monoxide poisoning, electrical fires, and other safety hazards.
- Code compliance. Our team is familiar with local licensing requirements to help you obtain the necessary permits while avoiding costly fees and penalties.
- System efficiency. Our experts can make sure your new furnace is properly sized and installed to improve energy efficiency, lower monthly utility bills, and maximize your comfort.
- Warranty protection. Most manufacturers require professional installation to keep warranties valid. DIY work could void your coverage, making it crucial to call a trusted local heating company for your furnace installation needs.
