Why Your Air Conditioning System Needs Prep Work for Summer’s Long, Hot Run

May 17, 2018
Hot Summer Ahead

If you’ve never jogged a mile in your life, how well do you think you’d do in a marathon? Could be a struggle, wouldn’t you expect? Maybe some huffing and puffing and conking out before the finish line?

Well, your air conditioning system is about to launch into a serious marathon through the summer months. And unless you want it to huff and puff and conk out before the cool temperatures return, you’d be wise to get your system ready. 

Great athletes know that they can’t jump into their sport of choice and take home gold medals just when it’s convenient. They’ve got to prepare for the long run. Similarly, your air conditioning system needs some prep work to make sure it’s ready for the endurance test it’s facing.  

After a very cold winter across the country, we’re heading into a really hot summer, and you can expect your air conditioning system to see heavy action during the scorching days ahead. Your best bet for preparation is preventive maintenance, which can help you detect potential problems before they occur – while also improving your system’s energy efficiency.

Without preventive maintenance, the odds increases that your air conditioning system will lose its strength as it works harder and harder each day. With preventive maintenance, you can save money on energy bills while also helping avoid inconvenient repairs and shortened equipment life.

What does prep work involve? Your check-up checklist will include checking refrigerant levels; inspecting and cleaning coils; checking and tightening electrical connections; oiling parts and motors; checking blowers and grilles for clear air flow; testing and calibrating your thermostat; and changing or cleaning air filters.

Because your systems are sealed for their protection and your safety, only professional service personnel should conduct this thorough annual service. We’d be honored to have you trust your system to us. Let us hear from you.


Is There a Dust Storm in Your Home?

Is There a Dust Storm in Your Home?

It’s not that anyone actually likes dust. But those with sensitive respiratory systems respond to it far more poorly than other people do. In fact, they might have a dust allergy. It kicks into gear after a round of vacuuming, sweeping and – yes – dusting. And the allergy signs of runny eyes, nose and sneezing pop up – or even move into asthma symptoms, such as wheezing and shortness of breath.

The American College of Allergy, Asthma and Immunology says there are several things homeowners can do to reduce house dust allergens that are causing problems in your family. For example:

“Dust” is, by the way, a sort of all-encompassing term for a mixture of substances. Under the microscope, the composition could show dust mites, cockroaches and other pests, mold or pet dander.  And any of these elements could cause an allergic response.  But, of course, the dust in one house may be different from the dust in another.

If you’re concerned about the air in your home, we can help. We can conduct a simple indoor air quality analysis to give you the information you need to make good decisions for your family’s respiratory health.

Planning Ahead for Your Next Furnace

Planning Ahead for Your Next Furnace

 Hope you’ll take this thought with the optimism with which it is presented: “Nothing lasts forever.” There are lots of reasons why that’s a good thing. For example, do you really want to be placing your mobile calls on a phone the size of a man’s shoe (some seemed that large)?  Do you want to be using a dial-up modem (if you know what that is) to check your email?

That’s what the march of time does. As technology improves, older stuff gets further and further behind. Outdated. Inefficient. Breaks down too often. Costs more to keep up than it does to replace.

We’ve all been there. And some of you may be in just that place with your home heating. So how do you know if you’re really there now? Well, when it’s time to replace your furnace, there are some signs you can look for. In particular:

Increasing Age/More Frequent Repairs – That speaks to the first point: nothing lasts forever. If you have a furnace 15 to 20 years or older, you’re facing a situation where you will need an increasing number of repairs. You’ll see this especially in the last two years of furnace life. Plus, as older models continue to age, their replacement parts will be harder to find – meaning, repair delays are another sign.

Higher Energy Bills – A furnace in its declining years will lose its efficiency, and you’ll see that in higher energy bills. In addition, since technology improves over time, the efficiency of these new systems is the best that’s ever been. So you’ll find you’re operating a piece of equipment that is far less energy efficient than the very high-efficiency models now available.

Inconsistent Comfort – Are some rooms too hot or too cold? Are you often adjusting the thermostat? The inability to stay comfortable is a sign that your furnace isn’t able to distribute air properly.

Strange Noises – Actually, this is a universal sign for almost any appliance or piece of equipment. If something doesn’t sound right, there’s probably a reason. Banging, popping and squealing noises, or a blower that turns on and off too frequently, are not the soothing, comforting background music for a cozy evening at home. Get it checked out.

As you keep your eye on frequency of repairs, cost of repairs, cost of energy bills and lack of consistent comfort, let us give you a big-picture look at your home’s energy use to help you in your decision.
