The size of the furnace system you require is determined by many variables, which include the size of your home, the climate in your area, and the level of insulation in your home. A qualified HVAC professional must perform a load calculation to figure out the proper size of the furnace system for your residence.

Essentially, a load calculation considers factors like your home’s square footage, the total number of windows and doors, the quantity and quality of your home’s insulation, and the environmental conditions in your area. An HVAC technician can use this information to calculate your home’s heat loss and gain and suggest the appropriate size furnace system to meet your heating needs.

Having said that, it’s critical not to rely on a rule of thumb or guesswork when deciding the size of your furnace system, as an undersized or oversized furnace can result in ineffectiveness, higher utility costs, and possible malfunctions. Therefore, if you’re considering a new furnace for your home, we advise you to partner with a reliable HVAC company for assistance, as a qualified HVAC professional can carry out a load calculation and suggest the right size furnace system for your home.

One of the primary worries that homeowners have when replacing an old furnace with a new one is whether or not the newly installed unit will fit in the same space as the old one. The good news is that in the majority of instances, a new furnace can be installed in the same place as the old one.

 However, certain variables can have an effect on how the installation goes. For instance, if your current furnace looks especially old or out-of-date, the new unit may be either bigger or smaller in size, making it challenging to fit in the same space. Furthermore, if the new furnace has a distinct venting system from the old one, the ductwork or chimney may need to be adjusted to suit the new system.

It’s critical to have a professional HVAC technician evaluate the space in advance to ensure that your new furnace can be installed in the same location as the old one. With that being said, don’t be concerned if the new furnace can’t be installed in the exact same location as the old one. Other options are usually available and will be dealt with by your partnered HVAC technician, so you don’t have to worry about any of the related stresses! The ultimate goal is to work with a qualified and reputable HVAC company that can assist you in selecting the right furnace for your home and ensuring that it is correctly and effectively installed. You can have a cozy home all winter long if you have the right team on your side!

Warranty agreements for new furnace systems differ based on the company that makes them and the furnace system. Warranties typically cover imperfections or problems with craftsmanship that cause the furnace to break down or fail within a specified time after installation. The warranty period can also range according to the manufacturer.

 Most commonly covered by a warranty for a new furnace system consist of the heat exchanger, blower motor, and igniter, along with other essential system parts. However, it is critical that you carefully review and comprehend the terms and conditions of your warranty in order to understand precisely what is and what is not covered.

Further to this, it’s also worth noting that warranties rarely cover damage or problems caused by incorrect setup, a lack of upkeep, or user negligence. Regular inspections and upkeep of your furnace system are required to ensure that it operates successfully and that the warranty is not voided. If you have any questions about the warranty for your furnace system, we recommend that you reach out to the manufacturer directly or the HVAC company you purchased and installed the unit with.

For many different reasons, installing a furnace is not a do-it-yourself project. Working with gas lines, electrical wiring, and ductwork can be hazardous and complicated during furnace installation. An installation error can result in gas leaks, poisoning from carbon monoxide, electrical shock, and even fires. Furthermore, the self-installation of a furnace can invalidate the manufacturer’s warranty and may not comply with local building standards and safety laws.

 It is always best to have your furnace system installed by a licensed and experienced HVAC contractor. They have the necessary training, knowledge, and specialized tools to complete the job securely and efficiently. They can not only ensure that your furnace is installed correctly but also provide ongoing repair and maintenance services to keep your furnace running smoothly and reliably.

What Homeowners Say About Us

I was very impressed with Oosterveld Heating and AC and would definitely recommend them. Phil came right away and provided an excellent quote for the combination boiler hot water tank for my 1948 home with radiators. The install team was excellent and did not leave a mess behind. I am very pleased with the system and how efficiently it runs. The girls in the office are very friendly and followed up after the install to make sure I was a satisfied customer.”​
