Dirty Evaporator Coil? How to Clean an AC Evaporator Coil

This entry was posted in Air Conditioning on by .

A well-functioning evaporator coil is essential to the operational efficiency of your furnace or air conditioning system. It also impacts how your heating system works if you’re using a heat pump. If your evaporator coil is dirty, that keeps it from absorbing enough heat, which means the refrigerant running through the evaporator coil isn’t warming up as much as it should. That’s very bad news, as a cold refrigerant creates water vapor in your air to freeze, instead of condensing that into a liquid. As a result, the evaporator coil can end up frosting over. Don’t let that happen. Cleaning the coil will do a lot to restore function and ensure a longer service life for your AC. If you’re wondering how you could go about cleaning that AC component, here are a few tips to help you.

How to Clean the Evaporator Coil

This task is easy enough to do. If you want to try a DIY approach to the problem, then follow these steps on how to clean evaporator coils:

  • First, turn off the air conditioning system. Switch the thermostat to off and unplug the unit. That way, you won’t need to worry about the AC accidentally turning on while you’re tinkering with its parts.
  • Once that step is done, remove the access panel on the furnace. It’s the same if you have an air conditioning system. Lift that panel and you’ll expose the coil.
  • Spray a no-rinse cleaner on the fins of the evaporator coil. Make sure you read through the instructions properly, though, before you direct the spray cleaner can to the coil.
  • If there’s debris that just won’t let go, then use a gentle nylon brush or paintbrush to clear that away.
  • Put the access panel back once the coil is clean, turn the AC back on, and you’re done.

If you want to try your hand at taking care of this task on your own, then these are the steps you’ll need to follow. However, if you have no time for this, or you’d rather let a professional handle this in case you’re afraid of making a mistake—perfectly reasonable concerns, of course—then start looking for a technician. Here are other reasons why you’ll want to get a pro for the job.

Why Should I Hire a Service Contractor?

The task might seem easy enough to handle. And if your only issue is with cleaning the coil, then you can expect to spend no more than a few minutes on the task or at the very least, the better part of an hour. However, if there are other issues that arise, or already existing problems, you’ll need to do more than clean the coil to get your AC unit working without a hitch. That’s where a professional comes in. Hiring a service contractor means you have an expert who can look at the problem, determine what’s causing the issue, and provide a solution. Pros also know what signs to watch out for, what faulty components are likely at the root of your problems, and what can be done to fix the situation.

Should I Repair or Replace?

In some cases, though, repairs can only get you so far. If you’ve hired a proto look at the problem and the contractor points out reasons why it’s better to replace your AC unit rather than spending money on one repair after another, listen to that advice. Take it to heart. If the repairs have been more frequent lately, then you’re only doing stop-gap measures. Stop throwing money down the drain and start looking around for a replacement AC unit. The sooner you get a new unit in place, the sooner you can forget your worries.

Should I Get a Maintenance Plan?

One of the best things about hiring service providers these days is that many of them offer maintenance plans. Anyone with an AC unit knows how inconvenient it can be to keep tabs on your AC’s maintenance schedule. Paying for a maintenance plan, though, means that someone else will handle that from now on. They’ll take it off your hands, so you won’t need to worry about forgetting to hire a service contractor to clean and perform maintenance service on your unit.

How Do I Choose a Technician?

Now all that’s left is for you to hire the right technician for the job. There are plenty of options, for sure, but not all of them will be the right ones for your needs. Here’s a list of tips to make this easier for you:

  • Ask around. It wouldn’t hurt to reach out to people you know and trust in the area. Reach out to them for recommendations and suggestions on which service companies for AC repairs and maintenance satisfy their needs. What company do they call?
  • Do your homework. Start looking for companies that fit the bill. Which ones offer the services and maintenance plans you need? Be sure to go over the plans. What are the terms and conditions?
  • Check the reviews. What’s the reigning feedback about the company? Are there a lot of positive comments or are there a ton of negative reviews?If there are even complaints lodged against the company, then spare yourself the trouble. Look elsewhere.
  • Hire local. When you hire a service provider, start with local options. They’re much more likely to make room for you on their calendar, especially if you’re close by. The proximity means that they can get to your home with ease. Take advantage of that.
  • Know the signs. Be on the lookout for any signs that you might be dealing with a dodgy service provider. Listen to your instincts. If they’re telling you that something is off, walk away and start looking for a trusted technician.

Whether it’s to clean the coil, perform repairs or maintenance, and even install a new unit, hiring the services of a professional technician will go a long way to giving you peace of mind.

3 Reasons Why Fall Is the Right Season to Purchase a New Air Conditioner

This entry was posted in Air Conditioning on by .

After a long, incredibly hot summer with record-breaking temperatures, we’re thankfully seeing the first glimpses of relief. Temperatures are beginning to drop, making it an ideal time to begin the process of purchasing a new air conditioner. The following are just a few of the key advantages of buying a new AC unit in the coming months, rather than waiting until next spring.

You’ll Eliminate Any Chance of Installation Delays

Spring and summer are incredibly busy seasons when it comes to air conditioner installations for good reason. Many homeowners wait until their unit has failed before they purchase a new one. Thus, when temperatures rise, and they experience a system failure, Cool Blew is called. A simpler option is to buy a new air conditioner now, so that you don’t have to deal with the problems of a failed air conditioner.

Consider that a new air conditioner will run between 10 and 20 years, depending on usage, maintenance and environmental factors. If your system is approaching or past this mark, you may want to start planning on a replacement sooner than later. By buying a new system in the fall, you’ll not only avoid any potential installation delays, you’ll also set yourself up for lower cooling bills with a higher efficiency system.

You’ll Have Time to Research Your Options

Buying an air conditioner while dealing with an unexpected breakdown is stressful by anyone’s standards. In the heat of the summer, when your indoor temperature is climbing, it’s easy to get sucked into purchasing a larger, more expensive unit than you actually need.
By planning your air conditioner replacement while your system is still running, you can carefully compare your options and make a decision based on facts, rather than urgent need.

Your Best Pricing

While we, at Cool Blew, always strive to deliver the best pricing options for your next air conditioner, lower demand in the fall can often add up to greater savings. HVAC suppliers often have systems on hand that didn’t sell over the summer that they’re willing to discount to make room for new models in the spring.

Your Residential Air Conditioner Specialist

At Cool Blew, we understand that purchasing a new air conditioner is a big decision that requires careful planning and evaluation. This is why we offer access to our experts by phone and free estimates on new air conditioners. Call us today at 623-872-2900.

Evaporator Coils – How Often Should Evaporator Coils Be Cleaned?

This entry was posted in Air Conditioning on by .

Don’t let the summertime heat or winter season get the best of your air conditioning system. Keep your unit working without a hitch with routine maintenance. That includes having the evaporator coils cleaned at least once a year. However, if the dust levels are high in your home or facility, then you need to get the coils cleaned more often.

What are evaporator coils?

Air conditioners don’t actually create cool air in your home, contrary to what some believe. What the system does instead is to condition your air or cool it by removing heat from the air that’s already inside. There are two types of air conditioner coils that do this: the evaporator and condenser.Evaporator coils—located inside the AC assembly—remove the heat and humidity from inside your home. Condenser coils, on the other hand, are units outside of the AC system that use refrigerant to transfer heat from inside to the outside of your home.

Why keep the coils clean?

Clearing the coils of dust allows the heat exchange to occur much more efficiently, allowing it to power through the coils. Dirt and debris can block the exchange, though, which could be why your energy bills are so high. Dirty coils force your unit to work so much harder, so you also get higher energy consumption levels and bills.

How often should they be cleaned?

You’ll want to get those coils cleaned at least once every year along with a seasonal tune-up. However, if there are high levels of dirt and dust at your location or site, you’ll need to get the coils cleaned with greater frequency.

How do I clean the coils?

Evaporator coils are inside the unit, which means you’ll need to open up your AC system to get to the coils. That’s easy enough with DIY manuals and online tutorial videos. However, only attempt a DIY approach if you are confident about your ability to follow instructions. If that isn’t the case, it’s best to hire pros. An expert knows how to clean evaporator coil.

Why should I hire a pro?

A professional has the experience to pull this off. The right credentials and qualifications mean that if something comes up during the cleaning process, an expert is in a much better place to address or resolve those issues or even nip potential problems in the bud. A proalso has better tools along with considerable industry knowledgethat’s up-to-date and accurate that ensures safety during the installation as well as stellar results.

How do I choose a pro?

Look for a business that offers AC maintenance & cleaning services. Ask them if they clean evaporator coils just to make sure you’re covered. One way to solve all your AC maintenance problems, though, is to go for a maintenance plan. That way, even when you’re busy, your AC unit won’t be neglected. You won’t have to worry about forgetting the next tune-up or having your unit checked for issues. The maintenance program should take care of that for you.

How Does a KVAR Unit Work?

This entry was posted in Air Conditioning on by .

Before you ask about how a kVAR unit works, it’s essential to know a few things first. Let’s start by being clear about what kVAR is. That means talking about the power factor.

What is the power factor?

The term refers to the ratio between active power and apparent power. Apparent power is the power we supply and is also called kVA. Apparent power is then broken down into two types: active power, which is symbolized kW, and reactive power, which is symbolized with kVAR. Essentially, though, the power factor is the measure of how effective the incoming power in your electrical system will be.

What are kW and kVAR?

Active power—or kW—is the one that supplies the energy for heat, sound, motion, and light. Reactive power, on the other hand, is inductive and is the energy that powers magnetic fields that are essential in rotating equipment. So, if something in the equipment moves, it’s likely operating under the inductive load. These are often in the form of compressors, refrigerators, freezers, motors, washers, dryers, dishwashers, pool pumps, and computer fans along with furnace blow motors, air conditioning units, well pumps, ceiling fans, and more. Now that you’ve answered the question: what is kVAR?, the next thing you should know about is a kVAR unit.

What is a kVAR unit?

You already know what the power factor is and its ratio of working power to total or Apparent power. To understand that with greater ease, the higher the kVar percentage in your load, the lower the ratio of the kW to the kVA. The result is a poor power factor. That’s where a kVAR unit comes in. It essentially reduces the reactive power that is supplied by the Utility. With the unit in place, you get to effectively use your electricity, reducing the amount of energy supplied to your system.

What does a kVAR unit do?

It increases the power factor, allowing you to make optimum use of your electricity. That matters because the reduced energy consumption levels mean that you save on electricity and energy costs. Installing a kVAR unit, then, is a smart cost-saving measure, one that you’ll want to take advantage of, so you won’t need to pay more than you need to.

Where is a kVAR unit usually installed?

Both residential and commercial spaces can benefit from the installation of a kVAR unit. Any facility or location that has a circuit breaker panel that comes with breaker switches is a good candidate for it. However, homes or facilities that still rely on the old screen-in type of switch will need to upgrade their systems before they think about installing a kVAR unit.

How do you install the unit?

Look for a reputable installation service that offers kVAR unit installation assistance. It’s always ideal to rely on the expertise and knowledge of industry pros. With their help and guidance, you can rest easy in the background. You know you can trust them to get the job done and done right.

Conserving Power While Maintaining Home Comfort in Times of Extreme Heat

This entry was posted in Air Conditioning on by .

As we continue to experience record-breaking heat in the greater Phoenix area, the possibility of power supply shortages grows. This week, both APS and SRP have asked customers to conserve energy to balance supplies. While we are not yet experiencing rolling blackouts like those in California, they are a possibility. To minimize the chance of experiencing an outage, we can all do our part to reduce our energy consumption. Here are a few strategies which can help:

Increase Your Thermostat Setting

Maintain a thermostat setting no lower than 80 degrees. To keep things cool, use ceiling or portable fans in occupied rooms.

Close Blinds, Drapes or Shades

Blocking the sunlight will help prevent your indoor temperature from soaring during the hottest part of the day.

Turn Off Lights

Check around your home for lamps and overhead lighting that are switched to on. Use only the lights that you need and consider switching to energy-conserving bulbs.

Use Your Outdoor Grill or Toss a Salad

Instead of turning to your oven or stove for meals, choose your outdoor grill or microwave. Or better yet, enjoy the bounty of summer fruits and vegetables and prepare a healthy salad that requires no cooking at all!

Use Appliances in the Evening

Wait to wash clothes and dishes until after the sun goes down. This will help reduce your energy usage during peak consumption hours.

Reset Pool Pump Timer

Like with indoor appliances, it’s a smart strategy to have your pool pump operating after dark.

Change Your HVAC Filter

A dirty filter results in your HVAC system having to work harder to keep your home cool. This simple step can go a long way towards conserving energy while improving your home’s air quality and the lifespan of your HVAC equipment.

The good news is that by taking proactive steps to reduce our energy consumption, we likely won’t have to deal with the rolling blackouts currently occurring in California. And by pitching in right now to conserve energy, you may also see the benefit of a smaller utility bill next month.

Coronavirus – Is It Safe to Use Your Air Conditioner?

This entry was posted in Air Conditioning on by .

With triple-digit temperatures now officially here, many Valley residents are once again turning to their air conditioners to keep their homes comfortable. Yet, with the continued advice to social distance and stay at home, it begs an important question. Is it safe to use your air conditioner?

Many homeowners have asked us this question lately – especially since the publishing of evidence that suggested that air conditioners may circulate infectious droplets of COVID19. While debate continues on how the virus is spread, nearly all health experts agree that the largest risk remains close contact with other people. In other words, if you’re practicing safe social distancing measures on a consistent basis, you have little to worry about when it comes to running your air conditioner.

Added Protection from Indoor Air Quality Solutions

Because most of us are staying inside due to the pandemic, indoor air quality has become more important than ever. Clean indoor air not only contributes to overall well-being and comfort, it can increase productivity – something that’s especially beneficial for family members who are working or learning from home.

An optimally functioning HVAC system can play an essential role in purifying indoor air from airborne contaminants, including bacteria, mold, mildew, and yes, viruses. So, it’s a great time to schedule an HVAC tune-up. Belts, condenser, evaporator coils and more are inspected and cleaned. Your filter will also be replaced as it serves as a first line of defense in indoor air quality.

At Cool Blew, we are also recommending to homeowners that they consider a complete cleaning of their air ducts to remove dust, mold and other microorganisms that can negatively impact air quality. For those who are at higher risk, we suggest the Air Scrubber Plus which has been shown to reduce up to 99.99% of harmful contaminants. The system uses advanced technology that is more than 50 times more powerful than standard air filters.

Call us today to learn more about our indoor air quality solutions and how we can help ensure your home’s indoor air is safe and comfortable all summer long.

Optimize Your Air Conditioner for the Summer

This entry was posted in Air Conditioning on by .

As desert residents, we all know the value of having a fully functioning air conditioner in the summer. You only need to step outside and feel the rising temperatures to be reminded of just how relentless our climate can be. So, it certainly provides peace of mind knowing that your air conditioner is ready to go when June arrives.

April Is Primetime for Air Conditioner Preparation

This month, temperatures are warm but still comfortable. It’s not only the perfect time to dig out those t-shirts, sandals and shorts, it’s also when you should be scheduling a spring tune-up of your air conditioner. Yes, there’s more to air conditioner maintenance than changing out your filter.

At Cool Blew, we recommend a complete inspection and evaluation of your HVAC system. Air conditioners are complex with many electrical, mechanical and moving parts that need to be checked and fine-tuned to ensure efficiency.

Consider a Programmable Thermostat

If your home still has an older, manual thermostat, spring is also a good time to consider replacing it with a smart, programmable thermostat that learns your routine and regulates settings according to your habits. With this heightened level of control, the thermostat will not only pay for itself, it will save you considerably over the coming months and years.

Avoid Summer System Failures

Small HVAC malfunctions now can be very disruptive in the middle of the summer. If you haven’t had your system tuned up recently or if you’ve noticed a loss of efficiency, unusual sounds or other potential problems, don’t hesitate to call Cool Blew. We’re here for all your HVAC needs and can ensure that you’re ready to go for when hot weather hits the valley.

Coronavirus – Safety Precautions

When Should You Turn on Your Air Conditioner?

This entry was posted in Air Conditioning on by .

We all know that spring-like weather starts early in Arizona. And this year is no exception. Temperatures are already starting to creep back up above 80 degrees. Although nights and mornings can still be chilly, many of us are tempted to turn on the air conditioner in the afternoon to cool off a bit. But before you touch that thermostat (and long before that first 100-degree day hits), it’s important to ensure your air conditioner is working optimally.

Spring Cleaning for Your AC

Like with the rest of your home, your air conditioner requires maintenance to stay in tip-top shape. Early spring is the ideal time to make sure it’s clean. This includes replacing or cleaning air filters, cleaning up dirt and debris around the exterior unit and cleaning the coil and condensate drain. If you don’t feel comfortable with any of these tasks, the team at Cool Blew is happy to help as part of preventive maintenance service.

Professional Tune Up

As part of preventive maintenance, you will also gain the advantage of having an expert technician ensure every component of your air conditioner is working optimally. If malfunctions are identified, they can be fixed in a timely manner. This means not having to experience an unexpected system failure on a summer day when cooling is critical. Even if you think your air conditioner is working fine, it makes sense to schedule a tune-up with an HVAC professional. And spring is the optimal time before the busy summer season begins.

Considering a New Air Conditioner?

If you’ve been putting off replacing an aging, inefficient system, we can help you with that, too. We provide free in-home estimates and can help you determine the best system for your specific needs. A new air conditioner will save you a substantial amount on your monthly utility bill and will improve your home’s comfort considerably.
