4 Things You Need to Know About Air Conditioning Maintenance

Nearly all literature related to air conditioning, from brochures to user guides, emphasize the importance of regular maintenance and timely repairs. Here are a few things you need to know about air conditioning maintenance, and why performing some maintenance tasks yourself can help with scheduled professional maintenance.

Heating and Air Conditioning Zoning: How It Works

There are plenty of ways to maximize energy use when it comes to heating and air conditioning; one popular option is zoning. Zoning assigns “zones” to different areas of your home and distributes heating and cooling according to their specific needs. These zones are controlled by a thermostat, which determines the temperature levels for every zone.

The Advantages of Mini Split Heat Pumps

Mini split heat pumps operate much like regular heating systems except for one major difference: there are no ducts. Consisting of an indoor unit that blows air over evaporator coils and an outdoor unit that powers the system, mini split heat pumps have many advantages to offer homeowners. To help homeowners better understand its ins and outs and determine if it is the air conditioning system for them, here’s a close look at its many distinct advantages.

Common Air Conditioning Problems Homeowners Should Know

When it comes to maintenance, prevention is indeed better than having to repair. The same holds especially true for heating and air conditioning systems. The more you know about them, the better you can care for them. Furthermore, by being well-versed about the common problems that can afflict them, you equip yourself with the knowledge to prevent them from happening in the first place.

5 Signs it’s Time to have Your Air Conditioner Replaced

It has always been very difficult to tell when a piece of home equipment needs replacement. So, how can home owners be sure that it is time to replace air conditioner or have it it repaired? We’ve put together this resource to help you make these tough decisions. Here are the tell tale signs to help you answer the question: When Should I Replace My Air Conditioner?

5 Ways to Know it’s Time to Replace Air Conditioner

1. When your energy bills soars

If your unit runs longer than normal to achieve same level of comfort, this could be a sign it needs replaced.

If you realize your energy bill is sky rocketing and it has not been particularly warmer than usual, your AC could be losing efficiency. This is worrisome, particularly if your HVAC gets routine maintenance from a trusted Kirkland professional; you change the filters frequently and ensure the equipment is kept clean.

2. Your nose tells you so

Even exterior AC units should not experience a strong, unfamiliar odor. In your regular inspection of your unit, don’t let any potent smells go unchecked by a professional. It could be a sign of a major leak or potentially, the system breaking down permanently.

3. The unit breaks down frequently

If the H VAC unit breaks down frequently, it’s time to compare the cost of constant repairs versus the cost of buying a new AC unit. Although tune-ups on the unit are not very expensive, frequent repairs add up and a new system will likely run more efficiently. A new system will also provide the peace of mind that your system won’t breakdown when you need it the most, especially in the summer months.

4. Your AC is more than 10-15 years old

An air conditioner that has been used for ten or so years should be replaced. Although it may be working just fine today, it’s days are likely numbered. You don’t want to have to find out that your system needs replace, especially in July. Moreover, it is quite common for modern equipment and manufacturing techniques to work twice as efficient as units made ten years ago. This may save you hundreds of dollars in energy bills each year.

5. It is Getting Noisy

If you can hear your exterior AC unit from inside your home, then it’s high time you acquire a new unit. The noise may be as a result of broken down components. It could also signal a problem with the indoor coil of the conditioner or the duct system may be undersized.

When should I replace my air conditioner?

The answer to this question is rarely a simple one. However, if you work with a professional, the transition from your old system to your new one doesn’t have to be uncomfortable financially or physically. Work with the professionals Cardinal Heating & A/C to replace air conditioner in Kirkland without compromising on home comfort or budget.

A Brief History of Air Conditioning

Did you know that people have been coming up with novel ways to keep cool for millennia? Your current whole-home air conditioner may be a modern convenience, but it is just the latest in a long line of cooling innovations. How did our ancestors stay cool in the summer and in hot climates? Take a quick tour of the brief history of air conditioning.

It All Started with Cavemen

Humans’ first homes were natural formations: caves. They not only provided protection from the elements and predators; they also provided a cool place to get out of the sun. These ancient ancestors not only understood that being underground was cooler; they took full advantage of it by living in caves and digging tunnels and burrows to beat the heat.

Egyptians Used Water to Get Cool

We know today that water can have a cooling effect, and some modern HVAC systems still use that principle. The Egyptians discovered this fact thousands of years ago and used it to cool their homes. They hung water-soaked reeds in windows to cool incoming breezes.

Ducts Were Invented in Ancient Greece

Today all of our HVAC systems use ducts to move warm and cool air through a building to heat or cool it. The ancient Greeks were the first to discover that this would be a good way to control temperature. They used water piped in to buildings to change cool rooms. The Romans took that idea and improved on it with air ducts under floors to move warm and cool air through bath houses and other buildings.

Thank China for Fans

We still use fans today because these simple devices are effective at cooling you down in the heat. It was in ancient China that people first realized that moving air cools and the fan was invented. Today we use fans in place of air conditioning systems, but also within them to move air around rooms and buildings.

Our methods for getting cool have changed over the millennia, but not as much as you may have realized. We still use fans, ducts, and even geothermal cooling, first discovered by our cave-dwelling ancestors.

Benefits of Financing Your New Heating and Cooling System

Sometimes heating and cooling systems break down at inconvenient times, and many homeowners haven’t been able to set aside enough money for such an expense. When you finance your heating and cooling system, you can get what you need right away, while being able to make comfortable payments toward your investment.

How Financing Your Heating and Cooling System Can Help You

Financing generally goes through a lending agency that works with the HVAC company. The lending agency handles the financial side of the transaction, while the HVAC company provides the service.

Ease of Mind

Financing can help individuals and families get needed repairs and replacements without having to worry about paying the entire amount up front. Having to make a large purchase can be traumatic and nerve-wracking, especially if the investment means that you’ll fall behind in other important areas. By financing your HVAC needs, you can continue to enjoy livable temperatures without having to break the bank.

Energy Savings

If you buy an energy efficient system, you’ll be saving yourself money each month in utility costs. For instance, replacing an air conditioning unit with a 10 SEER (seasonal energy efficiency ratio) with one with an 18 SEER can save you up to 48 percent in your annual cooling utility costs.

How to Obtain Financing

You don’t need to have perfect credit to qualify for HVAC financing. Gather the following documents so the lending institution can make a fully informed decision:

  • Credit report—A good credit score is an important factor in obtaining quality financing. The amount you’ll receive and the interest rate on the loan will be tied to your credit score.
  • Pay stubs—Gather the last three months’ worth of pay stubs for income verification. If you’re self-employed, bring proof of income through either deposit receipts or your last tax return. If you have others listed on the loan application as well, they will also need to provide proof of income.
  • Letters of reference—Some companies allow letters of reference, which helps them determine the outcome of the loan application. This is especially important if you have poor or minimal credit, as the letters can help show your reliability. If you’re able to provide reference letters from employers or utility companies, you can show that you’re consistent and financially responsible.

If you need to replace or repair your HVAC system and don’t have the funds to hire a contractor on your own, consider speaking with your HVAC company about financing options. Most companies understand their customers’ situations and offer finance applications as part of their regular service.

Can I Replace the Outdoor Unit on My Older Air Conditioning System with a Newer Model?

In some instances one part of a split-system air conditioner will stop working even while the other half continues to function. This happens most frequently with the outside cabinet (the condenser unit), where the compressor and the condenser coils work together to dispatch waste heat removed from inside the home.

If this ever happens to you, and you can find an exact duplicate, you certainly can change outer cabinets without disturbing the interior section of your air conditioner. But if your air conditioner is old it might occur to you to look for a more modern condenser unit, which would be more energy-efficient than your old one and could save you money as a result (you assume). You may have heard this is possible and technically you’re correct, it is.

But if such a thought ever enters your mind you should send it into exile immediately. Just because you can do something doesn’t mean you should, and that is definitely the case here.


Split-System Chaos and the End of Your Air Conditioner

HVAC technology is ever-evolving and always in the direction of faster operation and greater efficiency. In comparison to older models, for example, modern condenser units feature coils that have larger surface areas, more aerodynamically correct geometry, improved tubing and an overall performance profile that dwarfs anything manufactured 10 or 20 years ago.

This sounds great, but there is a fundamental disconnect between the past and the present that will cause trouble if you turn your old air conditioner into a half-modernized hybrid. With a system like this you’ll experience less efficient heat transfer and cooling, increased energy consumption, frequent breakdowns and finally catastrophic product failure.

This isn’t speculative—using standards established by the American Society of Heating, Refrigeration & Air Conditioning Engineers, manufacturers have tested various combinations of technologically mismatched air conditioning components and proved conclusively that mixed systems don’t work well and are essentially disasters waiting to happen.

In addition to poor cooling performance and excess energy usage, incompatibility between old and new AC components leads to imbalances in performance between inside and outside that will ultimately lead to compressor failure.

The aforementioned tests showed compressors were 45 percent more likely to fail in the first year if the outdoor and indoor units were not technologically compatible in every aspect, and even if compressors managed to survive longer they were still doomed to die young.


This Just In: Short Cuts Will Cost You More

While energy-efficiency is always good, the best way to get it with an HVAC set-up is to install a fully-integrated contemporary system. It will cost more in the short-term but in the long-term it is bound to save you money.

And if one half of your split-system air conditioner has already failed it’s a fair bet the other half isn’t in the greatest shape and may be nearing a meltdown anyway.
