When it’s time to replace your HVAC system, there are six typical mistakes to avoid.

1. Do not make the mistake of renting rather than purchasing your heater.

Because repair and maintenance are usually included, renting your furnace may appear to be a safe alternative. Leasing a heating system, on the other hand, might be substantially more expensive than purchasing the equipment directly. Be cautious: water heaters are protected by law, whereas furnaces are not.

If you need a new unit, don’t give in to the pressure of a salesman knocking on your door. Your safest bet is to take time and evaluate all the potential alternatives before making the final decision while picking the most energy-efficient device.

2. Don’t buy the first option you come across.

It is much wiser to look around for the finest heating system offered. Inquire about price quotes from the salesmen. Compare the items included in the budget, such as removal of your old equipment and permits; the quality and efficiency of the unit supplied; and, ultimately, the guarantee and level of service you are receiving. The service of the contractor who installs your equipment and the specialists who handle warranty concerns will most likely be reflected in the eagerness and excitement of the sales agent. Then you’ll know you’ve gotten the greatest deal available. Take your time and consider all your alternatives; you’ll be dealing with the HVAC unit for the next 10-15 years. Make sure that you select the appropriate brand for the installation of the new heating system.

3. Do not choose the cheapest option.

Although price is important when buying anything, the cheapest heating system may not be the greatest option in the long term. Consider your equipment to be a long-term investment. You’ll have the model for a long time, and the more efficient it is, the less money you’ll spend on energy bills.

Look for a heating system that is energy efficient and has a reasonable service agreement. There might be several reasons why the equipment is so inexpensive. There might be a short warranty period, or it could be an older model, making it very hard to acquire replacement components if the unit breaks.

4. Don’t overlook the AFUE ratings.

Even though many modern heating systems are classified as energy-efficient, they are not all made equal. The annual fuel usage efficiency, or AFUE, of a furnace, will be considered by a discriminating customer.

AFUE, specifically, is the ratio of yearly heat energy output to heat loss by your equipment. If the AFUE is 80 percent, then that means that 80 percent of the energy in the fuel is converted to heat for the residence and the other 20% is wasted. As a result, the model’s efficiency improves as the AFUE increases.

If your budget permits, aim to purchase a model with an AFUE of approximately 90%.

5. Ignoring the size of your property in relation to the heating system 

The heating system you choose will need to be more powerful the larger your home is.

If you choose a small model for a large home, the equipment may need to be turned on frequently to maintain your desired temperature. Higher energy expenses result, and your equipment’s life may be shortened as a result.

A furnace that can produce 40 to 45 BTUs (British Thermal Units) per square foot of your home is a decent benchmark to aim towards. If your home is 2500 square feet, for example, you should get equipment that generates 56 BTUs.

6. Do Not Try to Install Your New Heating system on Your Own

Installing a furnace, no matter how skilful you are, is best left to the professionals. For your new equipment to perform at its best, it must be properly installed. A unit that has been installed incorrectly may only work at half capacity.

Moreover, an improperly installed unit can be a danger to you, your family, and your home. It’s best to contact a skilled contractor in your area and be sure that everything works properly. There are numerous cases when the new furnace is installed improperly. As a result, you can expect – the HVAC unit works poorly, consumes significantly more electricity and 2 years is the best you can expect.

7. Make sure you don’t miss any maintenance recommendations for your furnace.

It’s very uncommon for contractors to install a furnace but then fail to instruct the consumer on how to use and maintain it. This means you’ll have to find out when to change the filters and how to control the thermostat on your own.

It’s also a good idea to inspect your equipment at least once a year to catch problems early. Many HVAC firms offer this service, and some even offer maintenance plans that include monthly inspections. If you don’t want to deal with HVAC problems in the future, it’s a good idea to think about this choice. Read the protection plan agreement carefully because some businesses leave off vital services such as compressor repair, annual examinations, and other critical and pricey parts.

Make sure to get verbal and written directions from your contractor on how to care for your new furnace.
