10 Common HVAC Issues & How Pros Troubleshoot Them

This entry was posted in HVAC Maintenance on by .

It’s important that you reach out to a trustworthy service technician when you come across signs that your AC unit isn’t working as well as it should. To make that happen though, you need to recognize the signs. Here are common HVAC issues—and how they look like or what their signs are—to help you. By knowing what to watch out for, you’ll know right away if you need to reach out to an HVAC service technician as soon as possible.

Clogged Filters

This is a common HVAC problem. Signs include compromised airflow. If there are hot and cold spots in your room or stuffy air, that’s a sign that you have clogged air filters. You’ll need to replace the filter to fix this issue. However, it’s easy enough to do. Have pros do this every two to three months on average. You can do this yourself but if you aren’t sure what to do, it’s better to hire pros of an HVAC repair company in Peoria to do the job.

Obstructed Condenser Unit

The condenser unit is typically located outside your home. However, being outside means it could get crowded around the unit. If there plants around the condenser, then that could cause the unit to get overheated. Is the unit always hot to the touch? Is it smoking? Don’t let it worsen. Before those things even happen, clear out the clutter around the unit.

Outdated HVAC Design

When you renovate your home, it’s smart to upgrade your HVAC unit too. An outdated HVAC system won’t be able to handle the needs of your home. If your unit isn’t cooling the room as well as before, or it doesn’t get as cold as before, then it’s time to replace that with a new one.

Slow Fan

Blower fans should work efficiently. If yours is slow and sluggish, that could be due to the grime and dirt that’s accumulated on the fan. This can also be one of the reasons why you’ve got poor airflow. Have a pro clean the fan to restore its smooth, efficient operation.

Low Refrigerant Levels

If your AC is leaking, that’s usually a refrigerant problem. Signs of this are compromised airflow and reduced cooling comfort. If this isn’t fixed right away, it could lead to the unit’s gradual decline in performance.

Blocked Vents and Registers

These are other common problems that HVAC owners find themselves dealing with sooner or later. One way to fix this is to check if you’ve misplaced rugs or furniture. Check if anything is blocking your vents or registers and then remove them.

Wrong Size

Big isn’t always better. You need a unit that’s just the right size for your property or rooms. Anything that’s too small won’t be able to provide the level of cooling comfort that you want. On the other hand, if you pick an oversized unit, it might often cycle on and off and might not remove the humidity in your space. The result is that you’ll end up feeling like your room is even stuffier or more uncomfortable than before. Pick a unit that’s properly sized.

Leaky and Blocked Ducts

Are your ducts leaky? Are they blocked? That’s another common problem that you’ll want to look into. Dust and dirt build up over time. That’s why you need to hire pros to check the condition of your ducts. If the airflow is impeded, then that means there’s a blockage that needs to be removed. It’s easy enough to get your ducts cleaned. Also, some ducts might have cracks or holes. That will affect the airflow of your unit as well. A professional service technician, though, will know what to do to repair the damage. Don’t try to DIY by putting duct tape on the cracks or holes, since it doesn’t really work well and is only a temporary measure. Stop-gap measures won’t help you in the long run. You’ll need to hire a professional to deal with the problem. Also, old ducts require a light touch. That’s another reason why you’ll need pros with expertise and the proper tools to make sure the ductwork isn’t damaged any further.

Dirty Coils

Dirt on the coils can lead to airflow issues. That’s why it’s best that you check the coil for dirt since dirt and dust build up over time. If there’s too much dirt and dust, the coil won’t be able to release the heat effectively and that’s why the air’s cooling comfort is compromised. If you don’t want that to happen, then clean those coils regularly. Hiring a pro to take care of this is convenient, though, as you can ask the technician to take care of all the other issues that need to undergo troubleshooting. To make it easier, you might want to come up with a list of the issues that you think your unit has. That should give the technician a bit of a guide on where to get started.

Eco-Friendly Home Tips to Make the Most of Earth Day 2021

This entry was posted in HVAC Maintenance and tagged on by .

April 22nd will mark 51 years of Earth Day celebrations. It’s a wonderful opportunity to take small steps toward changing your consumption habits. The ability to positively impact the environment around your home through simple fixes can mutually benefit your family, neighborhood, and ultimately our world. Let’s look at some ways to get involved besides classic Earth Day activities like picking up trash and tree planting campaigns. Here are eight eco-friendly home tips to save energy and natural resources.

Fix Leaky Faucets

A slow drip from one leaky home faucet can waste 7-10 gallons of water every day. That’s over 3,600 gallons a year, increasing your water bill by over 10% each month. That’s more than 60 showers annually! In other words, learn how to stop the drip and call in the experts, like Cool Blew, to ensure the water is only flowing when you want it to.

Turn the Faucet Off

What’s the best way to save up to eight gallons of water a day? Shut off the sink faucet when brushing your teeth! You can also conserve water while washing your hands. Turn off the tap when scrubbing your hands with soap before washing for 20 seconds.

Clean Refrigerator Coils

The condenser coils on the back of your refrigerator should be cleaned every six months by dusting or vacuuming. Keeping your freezer and refrigerator full helps to retain cold air better, utilizing less energy. Inspect and clean gaskets periodically to help your refrigerator operate more efficiently.

Vary Cooking Times

By cooking early in the morning or at night, you’ll reduce energy consumption especially if you’ve signed up for off-peak hours energy plans with your local utility company. When using your oven, turn it off 15 minutes before the timer is up. Your food will continue to heat up.

Turn on Ceiling Fans

According to Energy.gov, when using air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4 degrees Fahrenheit with no reduction in comfort.

Install a Smart Thermostat

Did you know you can save up to 8% on home cooling costs for every degree set above 78 degrees? By replacing your thermostat with a smart thermostat, you can earn even more energy savings with an environmentally friendly system which pays for itself.

Wash Laundry in Cold Water

Your washing machine uses almost 90% of its energy-related consumption towards heating the water. Choose the energy saving setting for your clothes. Hot water also can fade, shrink, or wrinkle certain fabrics. So stick to the cold.

Turn Dishwasher Heat Dry Off

One of the easiest ways to save about 15% of your dishwasher’s energy usage is to turn off the heat dry function. The air-drying cycle will dry your dishes and save money. If your dishwasher doesn’t have this function, simply crack open the door to let dishes dry once the load has finished washing.

It makes good sense for Earth Day to implement these simple, cost-effective, home lifestyle changes. It’s more important than ever to be environmentally friendly, and every tiny bit helps to save planet Earth.
Not everyone wants to take a DIY approach for Earth Day 2021. We get it! That’s why Cool Blew offers a team of licensed professionals to help you. Call the experts at Cool Blew today at 623-872-2900.

HVAC Strategies to Prevent Hay Fever

This entry was posted in HVAC Maintenance on by .

Hay fever season is here for an estimated 40 to 60 million Americans. If you’re one of the unlucky sufferers of this common condition, you’re probably already suffering from sneezing, sniffling, and itchy, watery eyes. Luckily, spring HVAC maintenance can remove many of the allergens that can cause symptoms of hay fever. Proper maintenance can remove pesky allergens like dust mites, mold, and pollen, helping you avoid irritating allergic symptoms. In fact, these common home contaminants found in your indoor air can be easily controlled.

Use high quality air filters

You know air filters are your first line of defense against poor air quality in your home. MERV is the filter industry standard. Filters with higher MERV ratings offer increased filtration. Look for MERV ratings of at least 8, with 20 being the highest rating. This will go a long way toward reducing indoor allergens. Replace air filters every month for best results. Dirty air filters not only will contribute to seasonal allergy symptoms, they also decrease HVAC system efficiency.

Clean the outdoor unit

The outdoor HVAC unit pulls in air circulating throughout your home. Airborne particles make the air in your home harder to breathe. Check for dust, dirt, and debris and clear it away from the unit frequently to keep allergens from being pulled into the system and entering inside.

Dust house vents

Even if you make it a habit to dust weekly you may forget to dust air return vents. Dust mites are the most common hay fever trigger, so cleaning your air ducts will get rid of dust mites and help reduce allergy and breathing symptoms. Cool air transported through air ducts can also lead to condensation and mold which is a major irritant for many allergy sufferers. Dust lingering in home vents and registers will blow throughout your home, so clean them on a regular basis. Use a damp or treated cleaning cloth to keep from kicking up dust particles and worsening your allergy symptoms.

Schedule an annual maintenance appointment

Spring allergy season is a great time to schedule HVAC maintenance.. Servicing by an HVAC professional will help reduce indoor allergens and ensure your system is healthy, and your air filtration system is dust and blockage free.

Why You Shouldn’t Tackle Do-It-Yourself HVAC Maintenance

This entry was posted in HVAC Maintenance on by .

You enjoy being handy around the house, making common household repairs with a wrench or screwdriver. We get it! Saving yourself a great deal of money and honing your handyman skills is rewarding. However, HVAC maintenance and repairs simply shouldn’t be something to add to your list of do-it-yourself projects.

The following are just a few of the many reasons why it’s wise to only let a skilled, experienced HVAC technician maintain and repair your system:

1. HVAC Systems Need Professional Tools

HVAC systems need to be periodically serviced, repaired, and carefully calibrated with equipment and tools designed specifically for HVAC specialists. Everyday tools are not only impractical when it comes to fixing your HVAC system, they can be risky.

2. Safety Threats

HVAC systems require knowledgeable and experienced technicians who are trained to minimize the risks of working with flammable, pressurized gas, high electrical voltage and environmentally toxic combustion fumes that have the potential of causing injury or even death.

3. Decreased HVAC System Capacity

Do-it-yourself repairs and system tune ups have a high likelihood of decreasing the operating life and efficiency of your system. Without professional training, you can make mistakes with the system that could prove to be difficult to resolve in the future. And there’s always the chance that you can unknowingly turn a minor problem into something major, which can lead to expensive repairs down the road.

4. Voided HVAC Warranty

Replacing parts on your HVAC unit with generic parts or performing any do-it-yourself maintenance will likely result in a voided warranty. You must work with an HVAC trained and licensed professional as all repairs and maintenance usually require documentation by the HVAC manufacturer. In other words, to maintain your warranty, don’t do the job yourself.

Call Cool Blew Instead

We know that it can be appealing to attempt a DIY project like HVAC maintenance. But, stop before you start. For expert HVAC maintenance that will keep both your warranty protected and give you peace of mind, call Cool Blew instead at 623-872-2900.

A trained professional can detect HVAC issues before they cause bigger system problems. The benefits of using a trained HVAC professional will far exceed the potential damage you may incur by doing DIY servicing and cleaning of your system.

Schedule Your Spring HVAC Maintenance

Spring is rapidly approaching with temperatures climbing, and flowers already in bloom. As you prepare for the seasonal shift, don’t forget HVAC maintenance.

The optimal time to schedule air conditioning maintenance is now. Damage or stress placed on your system over the past months can be addressed with some springtime attention. Air conditioning maintenance includes a professional inspection, tune up, and cleaning by a trained Cool Blew technician. We highly recommend scheduling bi-annual HVAC system tune ups—one in the fall for heating, and one in the spring for your air conditioner.

Why Is Spring the Right Time for HVAC Service?

Triple-digit temperatures will be here soon, requiring you to flip the switch on your air conditioner. It’s no surprise that late spring and summer are peak times for HVAC repairs, placing HVAC technicians in high demand.

When you schedule a professional tune up prior to when the peak temperatures hit, you’ll be guaranteed a convenient appointment. You’ll also gain the peace of mind knowing that your system is ready to keep you cool all summer long. Post-winter repairs can also be handled proactively.

Why put off HVAC maintenance for when we’re in the midst of a scorching heat wave? Be prepared by taking the preventive route. Schedule professional maintenance now, and you’ll be glad that you did this summer.

Show Your HVAC System Some Love This Valentine’s Day

This entry was posted in HVAC Maintenance on by .

Valentine’s Day is just around the corner. While love is in the air, why not show a little love for your air conditioning and heating system? The wonderful thing about caring for your HVAC system, is that it will reciprocate in the form of fewer repairs and lower utility bills. No, you don’t need to buy a box of chocolates or a dozen, long-stem red roses. But you do need to make these gallant gestures:

Change Your Air Filter

Swapping out that dirty old air filter is one way to say “I love you” to your HVAC system. Why? A clean air filter prevents your system from having to work harder than necessary to cool and heat your home. By doing this two-minute task, you will reduce your energy bills, prevent the overheating of system components, prevent frozen evaporator coils, and minimize uneven cooling and heating throughout your home.

Open the Vents

Closing vents doesn’t save energy, it actually makes your system work harder by causing a pressure imbalance. So, open the vents and let the love and air flow freely through the ductwork.

Call an Expert for Maintenance

Doesn’t your HVAC system deserve the best when it comes to regular maintenance? Don’t scrimp on or altogether skip seasonal tune ups. By scheduling regular HVAC maintenance with a qualified service technician, you can keep a healthy long-term relationship with your system. Remember – you should have your HVAC system maintained at least once or twice a year.

Want to buy your HVAC system something extra special this Valentine’s Day? Consider a maintenance plan that delivers the benefits of:

  • Priority service
  • No overtime charges
  • Discounts on repairs
  • And much more

Happy Valentine’s Day

Is HVAC Duct Cleaning Necessary?

This entry was posted in HVAC Maintenance on by .

With air quality more of a concern than ever, many of our customers have inquired about HVAC duct cleaning. They wonder if it’s a good idea or a waste of money. At Cool Blew, we’re here to provide you with honest answers and professional advice.

Air duct cleaning is not typically part of general HVAC maintenance, but there are times when it is a good idea. We follow guidance from the US Environmental Protection Agency (EPA) which recommends that air ducts in a home should be cleaned when:

  • There’s visible mold growth inside the ducts or other components of the HVAC system.
    Mold can make for dangerous conditions, including making you and your loved ones sick. If mold is found, you’ll not only want to get your ducts cleaned, you’ll also need to identify the cause of the mold and get it corrected.
  • Vermin, rodents, or insects are in the ducts.
    Whether you’re alerted to the presence of critters because you hear them or see evidence of their droppings, you’ll want to schedule a duct cleaning, along with an exterminator. You will also want to eliminate any sources of water or food that are attracting them.
  • Excessive dust and debris
    Over time, plenty of dust and debris can collect in your ducts. By looking at your air filter, you can gauge just how much is building up and being circulated in your home. By scheduling duct cleaning every few years, you can reduce allergens and help keep your entire HVAC system running more efficiently.

How Are HVAC Ducts Cleaned?

Ducts are primarily located above the ceiling or under the floors of a home. This means that it really does take an HVAC professional to clean them. At Cool Blew, our technicians have a specialized cleaning process that removes the debris from your ducts without causing any to spill out into your home. We thoroughly clean and sanitize ducts, always keeping your safety and comfort in mind.

Spooky HVAC System Problems and How to Fix Them

This entry was posted in HVAC Maintenance on by .

Halloween is here, and it’s time to turn our attention to those spooky, scary things that send shivers up our spine. Yet, being frightened by a ghoul or ghost is one thing, being haunted by a malfunctioning HVAC system is something else entirely. The best way to avoid an unexpected and unwanted air conditioner or heater problem is to schedule regular, preventive maintenance.

Without those twice-yearly tune ups and inspections, your HVAC system is at risk of some scary and potentially dangerous problems.

Loss of Cool Air or Heat

Neglected systems are prone to unexpected and sudden system breakdowns. And you know what that means? Yes, you got it. You’ll be dealing with an uncomfortable home and an unhappy household.

Reduced Airflow

Clogged, dirty air filters restrict airflow, create stress on your system and diminish indoor air quality. If you do just one thing for your HVAC system, make it regular filter replacements!

Overflowing Drain Pans

Yuck! Drain pans can leak and overflow if they’re not regularly cleaned. This can result in water damage, as well as unhealthy mold and mildew growth.

Misaligned Belts

A slipping belt can wreak havoc on bearings, pulleys and shafts within your system. This ultimately will damage the motor – resulting in higher utility bills and costly repairs.

Bearing Failures

Bearing cavities require regular lubrication to keep them operating effectively. If things aren’t maintained, you can expect to be dealing with costly issues of overheating and bearing failure.

Leaking Refrigerant

Refrigerant leaks, big and small, can reduce the efficiency of your system. With a routine maintenance visit, any refrigerant level issue will be identified and repaired.

Broken Compressor

Like filters and drain pans, compressor coils require regular cleaning.

Heat Exchange Failure

A faulty heat exchanger isn’t just a hassle. It can be downright dangerous – by causing carbon monoxide to seep into your indoor air.

What’s not scary? Making an appointment for a tune up of your HVAC system. Don’t wait until you’re dealing with the unexpected. Schedule some time with Cool Blew today.
