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.

The new year is finally here – time to wipe the slate clean and maybe even make a few improvements in 2021. While eating healthier or getting a solid eight hours of sleep each night are positive resolutions to tackle, they both require self-discipline and dedication to stay with them for more than a couple of weeks. On the other hand, vowing to take better care of your HVAC system is easy to accomplish while also delivering some significant benefits.

Are you ready to be a better HVAC system owner in the coming year? At Cool Blew, we can help. The following resolutions can extend the life of your heating and cooling equipment, while enabling you to improve your home’s comfort and save you money.

Change Your Filters Regularly

Your indoor air has contaminants that can trigger allergies, asthma and other health issues. When was the last time you changed your filter? If you can’t remember, it has been too long. Consider filter replacement a quick monthly task. Once you’ve done it a couple of times, you’ll be able to swap out a filter in less than 60 seconds. Not only will this improve your home’s air quality, it will help keep your system running more efficiently, too.

Invest in Preventive Service

Seasonal maintenance checks on your heating and cooling equipment can help keep moving parts functioning optimally. They’re also helpful for spotting problems early on before they turn into costly breakdowns. Call us any time to schedule preventive service.

Get Ductwork Inspected

HVAC duct leaks can cause temperature fluctuations in your home, along with costing you a lot of money. With a thorough inspection, duct leaks can be identified and repaired. You might be surprised by how much you can save with this one simple HVAC decision.

Invest in a Programmable Thermostat

Gain better control of the temperature in your home in 2021. With a programmable thermostat, you can easily set the right temp for when you’re home and when you’re not, as well as different times of the day and night. Trust us when we say that it will help you save on your monthly utility bill while making your home much more comfortable.

Get More HVAC Knowledgeable

By learning about your HVAC system, you can become more proactive about identifying and addressing minor concerns before they become serious issues. Even if you don’t want to tinker around with the system yourself, having a basic understanding of how heating and cooling systems operate can be downright helpful. You may even find yourself offering a few tips to others, too.

Wishing you and your family the best HVAC year ever!

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.

Have You Been Putting Off Air Conditioning Maintenance?

This entry was posted in HVAC Maintenance on by .

Procrastination is a problem for many of us. Whether you tend to put off dental cleanings or stall until April 15th to pay your taxes, waiting for another day is a common human trait, but also one that is rife with risk. In the case of air conditioning maintenance, procrastination can lead to an array of costly and inconvenient problems.

Out of Sight, Out of Mind

It’s easy to ignore maintenance when your system seems to be working fine, but this can be a costly mistake. Remember the old idiom, “An ounce of prevention is worth a pound of cure?” Well, it’s definitely a true statement. By changing your filters and having your system cleaned on a regular schedule, you can greatly minimize the chance of having a major breakdown.

Diminished Efficiency

Even if you’re lucky enough to dodge a system failure, HVAC procrastination will cost you when it comes to energy efficiency. Dirt buildup, clogged drains and leaky ductwork can all result in your system working harder than it needs to. By simply scheduling maintenance service with Cool Blew, you can avoid wasted energy consumption and sky-high utility bills.

Lack of Comfort

An air conditioner that’s not getting the attention it deserves will also lead to problems with maintaining a consistent temperature. Neglect will result in poor indoor air quality and even wiring hazards. Want home comfort? Schedule maintenance service today!

Replacement Sooner than Later

A properly maintained air conditioner should last you at least 15 to 20 years. Yet one that has been ignored will often fail in under 10 years. With at least five more years of service, you’ll substantially lower your cooling costs.

If you’ve been putting off getting maintenance or keep forgetting to call for service on a minor problem, take this opportunity to pick up the phone and call Cool Blew now. Yes, it’s late in “air conditioning season,” but you’re likely to still be using your system until late fall or even into the early days of winter. In other words, you still need your air conditioner. And procrastination only makes any problems you have even worse. Call Cool Blew today at 623-872-2900.

Protecting Your HVAC System During an Arizona Monsoon Storm

This entry was posted in HVAC Maintenance on by .

Although monsoon season officially started on June 15th, we still are awaiting the dramatic conditions that come with this annual weather phenomenon. With humidity now finally starting to creep upwards and tall cloud formations building in the afternoon sky, we’re likely to begin seeing those monsoon storms, here in Phoenix, very soon.

While these storms are exciting to watch, they can wreak havoc on your HVAC system if you’re unprepared. So, we wanted to provide you with some timely tips as we enter this wild and wooly time of year.

Stock Up On Air Filters

High amounts of dust and other contaminants and particulates circulate through the air during summer storms in the Valley. And they can end up being sucked into your home and through your HVAC filter. To ensure clean indoor air quality throughout the summer, get into the habit of replacing your filter at least every 30 days. Choose a pleated filter that offers increased surface air to collect the maximum amount of debris.

Add a Surge Protector

With summer monsoon storms, lightning strikes can cause electrical surges that can trip your home’s circuit breaker and even kill power to your air conditioner. With a surge protector for your air conditioner, you can protect your breaker, your AC unit and eliminate a costly service call to get everything back up and running.

Clean Up the Yard

Winds often exceed 50 miles per hour during an Arizona summer storm, sending tree branches and loose debris flying. If they get blown into your air conditioning unit, they can damage the rather delicate coils that surround it. As we’re entering the thick of monsoon season, take some time to look around your yard for overgrown landscaping and loose items that can potentially go airborne. And remove them!

Call for Maintenance

Although monsoon storms can bring some relief from triple digit temperatures, it’s still very hot. In other words, you’ll still be relying on your air conditioner for many months to come. So, if you haven’t already, call for preventive maintenance to ensure your air conditioner is up to the challenge of keeping you and your loved ones cool and comfortable.

Your Home’s Air Ducts and Your Utility Bill – What You Need to Know

This entry was posted in HVAC Maintenance on by .

It’s that time of year when air conditioning isn’t just a refreshing option. Arizona homeowners know that without the continuous hum of their air conditioner, indoor temperatures can quickly climb to uncomfortable levels. And, with around-the-clock air conditioning comes higher energy bills. In fact, it’s very common for electricity costs to jump by 50 percent or more during the summer months. While turning off the air conditioning certainly isn’t an option, there is another way to effectively lower costs.

Many homes have a hidden HVAC problem that causes energy waste and higher-than-needed energy bills. What is it? It’s old ductwork.

In many homes, older ducts have leaks and creases which enable cool air to escape to the outside or internal areas that don’t require conditioned air. Outdated ductwork can also cause unequal cooling throughout a home and increased humidity, as well as musty, foul odors. Yuck!

If your monthly electricity costs seem to be skyrocketing, your ductwork could be the culprit. It’s time for a home energy audit. At Cool Blew, we start with a thorough inspection of your home’s ductwork. If leaks are detected, we will provide you with a detailed quote on air duct sealing.

Why Trust Cool Blew for Duct Inspection and Repairs?

As your local HVAC experts, we have many years of experience repairing ductwork. We don’t use taping or mastic to seal air ducts. They produce less than quality results. Instead, we rely on the advanced technology of AeroSeal – an advanced sealant that ensures your ductwork remains airtight with a 10-year warranty. By fixing these leaks, cooling will be evenly distributed throughout your home, and your air conditioning unit will be blowing cool air only where you want it to go – saving you each month on your utility bill. And with a thorough cleaning of your ductwork, those musty odors will be a thing of the past, too.

Isn’t it time to get a better handle on your summer energy bill? Call Cool Blew today at 623-872-2900.

Maximize Your Air Conditioner Efficiency in 2020

This entry was posted in HVAC Maintenance on by .

While most of us aren’t running our air conditioners in February, there’s no disputing that they are essential throughout most of the year in Arizona. So, it’s a good thing that they’re built to last and work reliably for years.

Yet, like all good things, air conditioners can be taken for granted. Most work without a problem, even in extreme heat, without missing a beat. But, if they are neglected or not properly maintained, problems can happen.

The Time to Call Is Before There’s an Issue

Consider that your air conditioning system has many components – both inside and outside of your home. These include motors, switches, fans, vents and more. They all work together to generate comfortable, cool air. Keeping this mechanical and electronic symphony playing in harmony requires regular, preventive maintenance.

Choose a Trusted Provider of Air Conditioning Maintenance and Repair

Today’s air conditioners are complicated. You want an HVAC service provider that is both highly trained and experienced. Establish a relationship so that the provider can get to know your HVAC system. The goal is to get in the habit of twice-yearly service inspections (ideally in the spring and fall), so that you don’t have breakdowns in the hot summer months or in the chill of winter. Yes, air conditioners, as well as other HVAC, parts and components can wear out or malfunction – and at different times. With regular maintenance, potential problems can be identified proactively, and parts replaced before you experience a problem.

Don’t Forget Your Ductwork

In the dusty environment that we live in, ductwork isn’t something to ignore. Ducts are vital for delivering conditioned air to every room in your house. So, if they’re loaded with dirt or mold, you and your loved ones are breathing that in. As part of HVAC system efficiency and upkeep, make sure that your ducts are checked and cleaned.

Make 2020 the year for an air conditioner reset. Let Cool Blew help you maximize the efficiency and effectiveness of your air conditioner and entire HVAC system. Call us to schedule a tune-up and inspection today!

Is Your Heat Pump Leaking Refrigerant?

This entry was posted in HVAC Maintenance on by .

Just like your refrigerator and air conditioner, a heat pump requires refrigerant to work. Yet unfortunately, many homeowners don’t discover that their heat pump’s refrigerant levels are low until they’re experiencing a problem like icing or no heat.

Is It a Leaking Heat Pump?

Within your HVAC system, your air conditioner and heat pump both rely on refrigerant to provide an optimal temperature inside your home. And, it shouldn’t dissipate during operation. Instead, your HVAC system should convert refrigerant from liquid to gas and vice versa – never decreasing in volume. However, leaks can happen, and they often occur at connector points.

During the cold winter months, often the first sign of a refrigerant leak is an indoor temperature that begins to drop. You may notice that the heater seems to be running continuously. Yet, the temperature doesn’t seem to be matching the thermostat setting. If it’s getting chilly, and the heat doesn’t seem to be where it should be, it’s time to call for a technician.

What About Icing?

When a heat pump is leaking refrigerant, there’s often a snowball effect of problems. The first of these can be the heat pump’s evaporator coil. Because heat absorption is the refrigerant’s purpose, leaking refrigerant can prevent the coil from absorbing heat. This ultimately causes moisture on the evaporator coil to ice over. You may be tempted to scrape off the ice but note that this isn’t going to solve the problem. What you actually need to do is call an HVAC technician who can both seal the leak and add the necessary refrigerant to enable your system to operate efficiently.

Don’t Neglect a Refrigerant Leak

Low refrigerant isn’t an HVAC problem to put off for another day. The stress caused by this problem can leave you in the cold, as well as impact the compressor and drive up electrical costs. If you’re struggling with a lack of heat, call the experts at Cool Blew. We’re here to help you identify the cause of the problem and ensure that you’re up and running as quickly as possible.
