Frequently asked questions about furnace replacement companies

Buying a furnace and having it installed is a significant investment in the future of your home, and in your home’s day-to-day efficiency and comfort. There are a few factors to take into consideration when choosing a new furnace for installation. First, you’ll need to select the type of furnace that offers maximum efficiency. In order to get a furnace that is the correct size, it makes sense to have an HVAC pro come assess the size of your home and its insulation features. Also, depending on where you live, your furnace may need to meet certain permit requirements.

A furnace specialist will offer information on the relative benefits of choosing an oil, electric, or gas fueled furnace. Gas furnaces are quite popular because they save money on energy bills down the line even though they come with a higher initial investment. Also, a pro can help you research what kind of maintenance is necessary to keep your new furnace operating most efficiently. They can offer a furnace installation estimate, and walk you through any recommended HVAC accessories. It’s wise to consult a pro before buying a furnace to save money and headaches later on.

Homeowners can sometimes take their furnace for granted if the HVAC system keeps their home comfortable and warm without incident. However, if their furnace is over 12 years old and is starting to need frequent repairs, it might be time to think about replacing it. There are other warning signs that a furnace may have served its time. You might notice your energy bills going up for no apparent reason, or that the furnace is cycling too quickly and or making odd sounds. These are indications that it may be time to replace your furnace. It’s smart to consult a furnace pro to see if it makes sense to have your furnace repaired, or if it may be time for a replacement.

Replacing your furnace offers a number of benefits. If your furnace is an older model, the newer furnaces offer much greater energy efficiency and savings. Newer furnaces often come with programmable thermostats, which raises the system’s efficiency even higher. Replacing your furnace can offer the comfort and security of knowing you can trust your HVAC system will work well for a long time to come.

If you’re contemplating saving money by installing your new furnace, it may make sense to think again. Even experienced HVAC technicians have been known to make mistakes. Furnace installation takes a great deal of knowledge and skill. Improper installation could result in dangerous consequences. A homeowner could unknowingly put their family in the line of trouble by improperly installing a flue or gas connection. Hiring a furnace installation contractor means that not only are you paying for their time, experience and access to tools, you are paying for a guarantee that the tech will fix any errors made in the installation process.

If you are a homeowner considering a furnace installation it could be in your best interest to do your homework in advance. Make sure the furnace pros you choose to hire are licensed and insured. Check that they are qualified to work on your brand of furnace. Finally, request a written guarantee covering the installation work. Hiring a furnace installation contractor can save you time and headaches.

In most cases, various municipalities require an HVAC permit to install a furnace. Gas and electric furnaces are vented appliances that need to be installed correctly in order to operate safely. If the contractor has pulled a permit, you have the assurance that this furnace installation pro is licensed, insured, and bonded. Additionally, when a permit has been pulled for a furnace installation, the homeowner has access to required safety checks.

It’s true that some HVAC contractors avoid the hassle of pulling permits to install furnaces. However, this action could place homeowners at risk down the road. When a permit has been pulled for a furnace installation, the homeowner can be assured that the installation will be up to code. An improperly installed furnace can pose a number of threats to the safety of the home including potentially posing a risk of fire. In some states, if a contractor is caught operating without a permit in your home, they may lose their license and both you and the pro could be held liable. So, it’s wise to ensure that your furnace installation specialist has pulled the proper permits before starting the job.

When you’re investing in a new furnace, take into consideration the cost of installation. Installing a furnace is a tricky operation requiring a great deal of experience, the proper tools, and seasoned industry know-how. Even so, the most experienced HVAC pros can make errors in the installation process that need to be addressed before they create safety issues. It makes sense to factor professional installation into your furnace purchase budget.

The cost for labor that goes into installing a furnace will vary according to a number of factors. However, a common ballpark figure for the hourly cost of a furnace installation is $75. The installation process will typically take one full day or a little longer. If the new unit is a different size and shape from the one it’s replacing, the installation price may be higher. If it’s difficult to get to, or requires installing lots of new ductwork, the cost of installation will rise.

When you have your furnace installed, ask for a written warranty covering the labor necessary to make repairs if the newly installed unit does not run properly. The cost of a professional furnace installation is well worth the price. A professional installation will be safe, effective, and should come with a guarantee for peace of mind.

A typical furnace installation can take a full day’s work or a little longer. The furnace installation professional needs to undertake certain safety measures during the installation process. Even the most impatient homeowner will understand the virtue of allowing the HVAC tech the time they need to carry out a successful and safe furnace installation. The pro will check for carbon monoxide leaks and test the gas pressure. A qualified furnace installation contractor will carefully check all the gas and electrical connections during the installation. Once the furnace is installed, the HVAC pro will ensure the heat vents work properly and are free of any obstructions.

During the installation, it’s a good idea to ask the furnace installation pro where the filter is placed in the furnace and how to get to it for ease of changing the filter. Ask the pro about a maintenance plan, and how much time any furnace upkeep will require going forward. A good HVAC professional will be happy to walk you through your furnace’s operating instructions and review plans for keeping your furnace in top condition for years to come.
