We suggest having your furnace looked at and serviced before it gets cold. If you do this once a year, you’ll find that it both runs more efficiently, and it helps with your warranty should something go wrong. Manufacturers recommend annual inspections and maintenance. With this in mind, be aware that if there’s a problem, they’ll want to see proof you’ve kept up with maintenance. Another reason to maintain your unit is that it works better and prolongs the life of the furnace.

A natural gas furnace vs. an oil furnace have different answers. The lifespan for a gas furnace runs about 15-20 years, while an oil furnace has a lifespan of approximately 15-25 years. Now, this is when you’ve done well to properly care and maintain the furnace. The lifespan is extended based on how well you maintained the unit.

How old is the furnace? This is an important point to consider. How often are you doing repairs? We go by the $5000 rule. So, to do this, consider the age of the furnace. Now, multiply that by the cost of repair per year. Got your number? Okay, if that number is less than $5000, we say repair it. For example, say your furnace is around 12 years old, how much will the repair cost you? $500? Okay, now let’s multiply 12x500. That total $6000, which is bigger than $5000. In that case, it’s better to replace it.

When it comes to air conditioning units not cooling your home, there are a few things to check. First, is your unit set to cool, and your fan set to auto? If that’s not the issue, it could be anything from faulty wiring to dirty air filters to refrigerant leaks. Other issues can be a frozen evaporator coil or a dirty condenser coil. There are multiple things to consider, but the simplest to check are the most basic, such as your thermostat setting.

If you’re looking into the cost of installing central air conditioning, expect to pay somewhere in the range of $3,700 to $7000, though it can vary based on where you live, what your existing ducts are like, and based on the system you need. This information comes from HomeAdvisor.

While there’s a general rule of thumb, unfortunately it’s not always accurate. There are many things to consider when choosing the right size air conditioner. It’s actually a big complicated, but with the right tools, and taking into account certain factors, you’ll soon know what size unit you’ll need. We’ll consider things like how many windows and doors you have, and even what type, along with the number of people living there, ceiling height, and more.
