How long do air conditioning systems last?

On average, air conditioners can be expected to last between 15-20 years*. However, there are a number of factors that can impact your air conditioner’s lifespan, including maintenance, extensive use, and extreme weather conditions. A good reminder, the manufacturer recommends annual maintenance for proper function and longevity of your AC.

How do you know it’s time to replace your air conditioner?

When your AC is acting up, it can be difficult to determine whether repair or replacement is the best solution.

Below are signs that your AC needs to be replaced:

  • It is 15 years old or older
  • You have paid for several costly repairs in the last few years
  • It runs constantly without ever getting to set temperature
  • Your energy bills are consistently high
  • It makes loud rattling, screeching, or banging sounds
  • It is blowing hot air
  • It is constantly tripping your breaker or blowing a fuse

Why is my AC unit not blowing cold air?

If your AC is blowing hot air, or none at all, there are a number of problems you will need to rule out.

Common causes of this problem include:

  • Low refrigerant levels
  • Clogged air filters
  • Faulty AC compressors
  • Dirty condensor
  • Blown fuses

If your AC is blowing hot air, bring in a trust certified service tech from Standard Heating & Air Conditioning right away to get to the bottom of the problem. We specialize in troubleshooting and repairing all types of AC issues.

How long does a furnace last?

On average, furnaces last between 15 and 20 years*, but maintenance plays a big role in the lifespan of your system. A well-maintained furnace will last much longer than a system that is not.

What do you do when your furnace goes out in the winter?

If your furnace breaks down in the middle of winter, it is important that you do whatever you can to keep your home comfortable and safe while you wait for a repair technician.

Below are tips for staying warm and protecting your home if your furnace breaks down in the middle of winter:

  • Use a space heater (while you are home and awake)
  • Use a wood or gas fireplace
  • Open kitchen and bathroom cabinets to prevent pipes from freezing
  • Leave your faucets dripping to prevent water from freezing
  • Keep all your doors, windows, and curtains closed to insulate your home
  • Cook or bake, we suggest cookies!

Should I have my furnace inspected before selling or buying a home?

Yes. It is incredibly important that you have your furnace inspected by a professional before selling your home. Sellers are often obligated to disclose or repair any serious issues with a home to buyers, so it is important that you make sure your furnace is in working condition. This inspection will play a role in a potential buyer’s decision to purchase the home or move on.

Should I have my furnace inspected before selling or buying a home?

Yes, just as annual maintenance is important, having the furnace inspected before you buy or sell your home is important too. The reason to have an inspection is to verify that everything is working properly & safely both as a purchaser and a seller. Depending on the city, inspection can be required. When buying a home, it is important to request an inspection of the furnace to ensure there are no additional and costly surprises, should you purchase.

How long should my boiler last?

The average life of a well maintained boiler is 20-30 years.* However, there are a number of factors that can impact your boilers lifespan.

Signs that you need to replace your boiler include:

  • It is 20 years old or older
  • Your fuel bills are much too high, or have progressively increased
  • It takes much longer to heat up than it should
  • It is leaking
  • You have paid for several costly repairs in the last few years

What are the signs that my water heater is bad?
