Don’t wait for hot weather to service AC

Have your air conditioning system checked.

The heating, ventilation and air conditioning (HVAC) system that brought your business through one of the harshest winters on record also will be required to operate reliably during the upcoming summer cooling season.

Consider calling your service firm to arrange service and inspection of your HVAC equipment before the summer heat arrives.

In my days as a boiler inspector, owners of older boilers would frequently ask: “So, how much longer do you think [the boiler] has to live?” To which I would respond: “I cannot tell you what day it is going to fail; but I can tell you what kind of day it is going to be. It is going to be the coldest day of the year; and the boiler service guy is going to be buried with work.”

The same is true for air conditioning. Remember that:

  1. HVAC equipment  ̶  any equipment, for that matter  ̶  will fail.
  2. Failures are most likely to occur during times of high stress when equipment is most needed.
  3. Equipment life is best measured in hours of operation, not years of service.
  4. Repair/service is least available and most expensive during heat waves and cold snaps, when equipment failures peak and demand for repairs and services exceeds the available labor; after all, everybody’s equipment seems to fail at the same time

Before the cooling season starts, ask your HVAC provider to:

  • Inspect all electrical connections, heat exchangers and drains
  • Check refrigerant levels and make sure there are no leaks
  • Lubricate moving parts
  • Inspect and test thermostats and controls, watching for overheating
  • Check for good air flow

Oh, and check the filters. Clogged filters restrict air circulation in your environmental system, reducing efficiency and costing you more in energy expenses. Replacing a dirty filter is like putting money in the bank.

    Not to mention that you’re going to have a long, long wait to see an AC repairman in the middle of summer. They’re usually very busy and you’ll have to wait a week or two for someone to come out and fix your unit. That might not seem like a long time, but if you live in a place like I do in Northern California where it routinely goes over 100 degrees in the summer, two weeks can be an eternity. Get your HVAC system checked early and you won’t have to sweat it out come summer.

    I do agree that HVACs tend to possibly fail whenever they are very much needed at that time. This is why it’s very important that an air-conditioner follow a regular maintenance no matter how new or old it is. Clogged filters seem to be one of the major causes why air-conditioners fail. Thanks for the reminder.

    When I’m servicing a customers heating and air system–the question that I get asked the most is how often they should have routine maintenance. The answer is –twice a year. One visit for air conditioning and one visit for heating. You should have both checked before you need to use them. Preferably early spring and early fall. I consider heating inspections to be more important because there are dangers from fire and carbon monoxide inhalation. Air conditioner and furnace inspections are also very important because of the cost involved in operating and replacing these systems. If there are loose wires, bad parts, dirty coils, dirty filters, low freon etc. The heating and air system may still operate with the above mentioned problems in low load conditions. but when it gets warmer or colder outside it is likely that the units will break down or not be able to keep up. Not to mention–a lot of energy is being wasted from months of operating that way and it’s also putting a very heavy strain on the systems major parts. Straining your heating and air equipment by operating it in such conditions will shorten its life span and cost you money over the long run. Just one loose wire or not changing your air filter can potentially cost you thousands of dollars and leave you without heating or air conditioning for several days. Read more at

    Hello Wayne,
    Thanks for this great and informative post about AC servicing. If users service their AC before hot season, they can cut down repairing and maintenance budget a lot and can enjoy full comfort in hot seasons. Again thanks for this helpful blog.

    This was an amazing piece of information and i personally wanted to thank you for this. Also i wanted to request you to keep on writing and posting such high quality info.

    I agree that you should get your system checked out before summer arrives. Everyone else will realize they are having problems with theirs, and HVAC technicians will be loaded with work, and it may take time for them to get to your place. That happened to me one hot July when I was in college. It’s always best to be ahead in the game!

    Regular maintenance is the key to improve your AC’s longevity and efficiency.

    A maintained cooling system will run well, utilize less energy, and less cost to run.

    Many of us do not give much attention to the Air conditioning unless and until it’s the summer season. But, Repair or HVAC services will not be available easily during the summer. Thank you for sharing these tips. I will try to implement them.
