In Knots and Coils: Fixing Your Evaporator Coil

The loss of your air conditioning is probably the last thing you need in the midst of the relentless July heat.

And when you start to notice high energy bills in tandem with longer cooling times while lazing around the house, it’s easy to break a sweat in figuring out where, exactly, to point your finger. If this sounds a little too familiar, we’d like to take this opportunity to introduce you to a key element on your home’s cooling system: your evaporator coil.

A single piece of your overall HVAC unit, you may think to fix a damaged or inefficient evaporator coil would be a quick fix… but that isn’t always the case.

What is an evaporator coil?

The evaporator coil is the coil of your HVAC unit that aids in cooling and dehumidifying your home.

It is one of the most important components of your system, as it plays a major role in regulating your home’s temperature year-round.

How do I know if something is wrong with the evaporator coil?

If your home is becoming more hot and humid despite constantly turning down the temperature on your thermostat, your evaporator coil might be in need of attention.

For one, it may be an issue of cleaning. When the coil collects dirt and debris, it won’t be able to absorb any moisture from the air around it, rendering it essentially ineffective.

Leaks of the coil may also occur, however, when the joints are otherwise not connected well or if portions of the coil are corroded and weak. A leaky evaporator coil will lead to a loss of refrigerant in your overall HVAC system, and thus a warmer indoor temperature.

Okay, what do I do from here?

If the evaporator coil is in need of a cleaning or routine maintenance, a simple replacement may be all that’s in order.

But in some cases, replacing your entire unit may actually be more cost-effective. You should opt to replace the entire unit instead of a single coil if:

● Your A/C unit is more than 8 years old
● Your evaporator coil is an obsolete model
● Your evaporator coil relies on R-22 refrigerant (as the industry standard is currently being transitioned to the R-410A refrigerant)

If you’re unsure about what may benefit your system the most — or if you’re in need of a professional diagnosis for your evaporator coil — be sure to contact Bold City Heating and Air today! A locally owned and trusted Jacksonville business who is dedicated to ensuring that you experience the bold difference, we guarantee we can blow some cool air on your summer stresses.


Now that summer is here, you can anticipate walking out your front door and being slammed by a wall of humid air just about every morning, even if the sun hasn’t been up all that long.

One of the most common (and dreaded) factors about Florida weather, the humidity, is usually only escapable upon setting foot indoors and closing the door securely behind you. But what if it’s still humid in your home?

Why isn’t your HVAC system dehumidifying the air as it should?

  1. Your refrigerant is leaking
    A refrigerant leak is actually one of the most common air conditioning problems. Refrigerant is a working fluid that serves to remove heat and moisture from your home and effectively move it back outside.But your refrigerant lines are susceptible to daily wear and therefore… daily tear. And when they’re a little older, they’ll likely leak or lose overall cooling power, meaning your home will remain more humid until they are properly repaired.
  2. Your ducts are leaky

    If the rooms in your home are only becoming increasingly difficult to cool or heat during a given season, leaky ductwork may be to blame. When your ducts are not secure at the joints or are otherwise not properly sealed, outdoor air is going to pass more easily both in and out of your home, meaning you’ll be out of control of the indoor temperature and also out of more money as your electric bill begins to skyrocket.

    If you’ve noticed humidity creeping in where it shouldn’t, consider calling your local professionals to come and test your ducts for leaks. They can then seal or repair them accordingly.

  3. Your evaporator coils are dirty
    Evaporator coils perform a similar task to that of your refrigerant — they’re designed to absorb surrounding heat and moisture, rendering your home both cooler and drier. When your coils get dirty, however, they won’t be able to do their job. Thus, the humidity will move back in pretty quickly and spoil your summer comfort.If you believe your coils are covered in a layer of grime, you’ll want to hire a reputable air conditioning company to come out and clean them properly.

Don’t let the sweltering heat bog you back down. If you’re tired of the humidity and ready to take advantage of a free air conditioning estimate, contact Bold City Heating and Air today! Not only are we your trusted heating and air conditioning experts in repair, maintenance, and installation, but we’re dedicated to helping you experience the bold difference.

Why are my ducts making popping noises?

Why are my ducts making popping noises?

Hearing all sorts of snaps, crackles, and pops may be delightful when you’re pouring milk into your cereal, but not so much when you realize it’s your home making those noises. However, the good news is not all odd sounds are a sign of danger.

Popping ducts, for instance, are actually relatively common and easy to fix!

But if you’re wondering why, exactly, those popping noises are occurring, the answer is probably just the good ol’ Florida weather, which sees dramatic fluctuations in pressure throughout the year.

Ducts frequently pop due to changes in pressure, and both the size and shape of your overall ductwork will determine how your system will react to such changes in surrounding pressure.

For instance, round ducts are most capable of withstanding changes in pressure, which makes them the quietest duct shape. Rectangular or square ducts, however, will be more likely to pop. Similarly, pressure increases will cause your ducts to expand, leading to popping and rattling once they contract again.

In either case, you’ll want to contact your local professional to modify your ductwork properly, so as to increase your ductwork’s ability to withstand changes and pop less.

Additionally, your ductwork has a sheet of metal that will also expand or contract in response to pressure changes and the thinner it is, the more it will pop.

If you find that the popping is relentless even with round, clean ductwork, you may want to invest in a thicker sheet of metal for your duct system.

But here at Bold City Heating and Air, we understand that any noise your HVAC system makes just might be cause for stress, especially if you aren’t sure who to turn to. That’s why, if you’re left scratching your head over your ducts, indoor air quality, or general maintenance, be sure to contact us today!

Defeating Dust In Your Home: What You Can Do Differently

Defeating Dust In Your Home: What You Can Do Differently

If your feather duster is your weapon of choice, we commend you on your commitment to dusting and cleaning your home! But, sadly, a feather duster won’t arm you properly against poor indoor air quality if you’re not approaching your HVAC system correctly.

We get it — defeating the dust bunnies ravaging your home and health can feel impossible, especially when you’re contending with whatever pollutants blow through the front door with you on any given day. But it doesn’t have to stay that way.

So, before you reach for yet another allergy pill, here are three steps you can take to reduce the dust and improve the air quality in your home first:

Clean Out Your Ducts

Nothing makes you realize just how behind you are on your spring cleaning than… when summer rolls around. Seasonal changes aside, you know you’ve officially hit the, “it’s been too long” mark when you dust and dust and dust, but your sniffles just always come back around.

Step one to reducing dust is to simply catch up on cleaning out your ducts and ventilation system — take those particles out of circulation completely.

Seal Your Ducts

You’ve cleaned out your ducts? That’s great! Now, the key is to maintain them. Leaking air ducts are one of the most common sources of perpetual dust, which is why step two is to have your ducts sealed by a professional so that more dust isn’t simply pulled back into your system post-cleaning.

And if you’re not sure whether duct-sealing is warranted, we recommend you schedule a routine duct inspection with your local professionals.

Take Advantage of Your Thermostat

While you’re dusting your home, you can actually find a little help in the form of your thermostat. By switching your thermostat’s fan to the “ON” position, the blower will circulate air continually throughout your home, essentially pushing dust particles back through the return vent and trapping them in an air filter, making it easier to remove them altogether.

Once you’re done dusting, however, remember to switch your fan back to “AUTO” so that you don’t waste extra energy!

If you’re struggling to keep up with the battle to keep your home dust-free, know that you don’t have to give in to relentless sneezing and wheezing. Instead, be sure to call Bold City Heating and Air today! When you schedule an appointment with us, you’ll experience the bold difference both in and around your home.

Don’t Let Your Wallet Feel The Heat: Summer Energy Saving Tips

Don’t Let Your Wallet Feel The Heat: Summer Energy Saving Tips

We all know the allure of a heat-induced afternoon nap. Whether you’ve been mowing the lawn, watching the kids at swim practice, or just going for a walk, being out in the summer heat for too long during the day can really suck the energy out of you.

But does it have to suck the energy from your home and your wallet, too? The answer is no! Not if you take the right steps:

Watch your windows

One of the easiest ways to save money on cooling costs is to simply seal and cover your windows. Blackout curtains will deny entry of sunlight in your home, reducing the need for cooling by virtue of designing your own indoor shade. Also, be sure to check around your window edges, where cracks and structural inconsistencies can be the culprit for unwanted warm air flow — if you come across any leaks, use caulk as a quick and efficient DIY solution.

Program your temperature changes

Setting your thermostat to “cool” is the natural action to take when lounging around at home in the mornings and evenings. But during the day, you’re likely away at work while the kids are at camp or with a friend. When nobody is home, you can actually save money by turning your HVAC system off or setting your thermostat to a higher temperature. Particularly if you have a Smart Thermostat, you can program is to start cooling down prior to your return at the end of the day.

Invest in preventative maintenance

Nobody wants to be drenched in sweat and fuming further when their HVAC system breaks down during the blistering summer months. By investing in preventative maintenance, you’re not only prolonging the life of your AC system — thus avoiding costly replacements — but you’ll actually be saving your money by increasing your system’s overall efficiency. And as a bonus? You may actually protect your warranty, as many systems require annual maintenance by a qualified professional to stay active.

If you’re ready to start prepping your HVAC system for the summer, contact Bold City Heating and Air. We’re a locally owned and trusted company, so call us today to schedule your pre-summer inspection and experience the bold difference!

The Importance of Air Quality

The Importance of Air Quality

The heat of the coming summer has a lot of us around Jacksonville already reaching for the thermostat to bring in some cooling reinforcements against the sweltering temperatures. While the comfort of a well-cooled home or office is a nice sanctuary against the summer (or late spring) heat, that comfort can disappear quickly if you or a loved one are susceptible to the angry inflammation, stuffy head and watery eyes associated with seasonal allergies.

Pollen is a byproduct of the natural beauty that surrounds us here in Northeast Florida. And while we wish no harm on any of the beautiful local flora, we could stand to have less pollen to sneeze through in our homes. Pollen enters the house attached to shoes and clothes, and through open doors and windows. Proper maintenance and regularly changing out of the filters in your AC system are easy ways to fight pollen in your home.

Dirty filters and dusty HVAC systems can lead to problems with excessive condensation as well. One of the issues that comes with the rising temperatures of summer is an increase in the humidity in the air. This can lead to mold and mildew infiltrating your system due to clogged lines and blocked filters. The importance of maintaining and monitoring your HVAC system cannot be expressed enough.

Pet dander can also trigger sneezing fits, and the increase in temperatures can lead to your pets shedding their coats. Loose pet hair and excess dander often accompany an increase in temperatures when the seasons change. Regular brushing and general grooming are not only good ways to keep your pet healthy and happy, they’re excellent methods of minimizing the impact that pet dander has on you and your loved ones.

If you are experiencing any of these issues, don’t hesitate to give us a call to set up a consultation on cleaning, maintaining or replacing your AC system today!

Hurricanes & Your HVAC

Hurricanes & Your HVAC

June is right around the corner, and we understand that hurricane season might not have crossed your mind… YET. But it’s always better to be ahead of the curve and, in this case, you don’t want to get caught in the rain trying to prepare your HVAC system for a hurricane at the last second.

As May comes to a close, you’ll want to start to prepare for the upcoming season by learning about hurricane maintenance for your HVAC system sooner rather than later when the first named system is about to barrel its way to the Sunshine State.

Here’s what you need to know about how to take care of your HVAC should a hurricane head your way:

Cool Your Home First

You definitely should not be trying to cool your home in the middle of a hurricane. Be sure to cool your home by several degrees prior to the storm hitting the area. Once set to the proper indoor temperature, you’ll want to turn off the electricity and/or unplug your unit in order to avoid the danger that accompanies power surges and lightning strikes.

Secure Your Outdoor Unit

You don’t want the hurricane-force winds to take your outdoor unit with it, so be sure to get outside and secure all of the bolts around your HVAC system’s base and consider investing in condenser straps. If flooding is a concern in your home’s area, see if there is any way that you might elevate your unit in a timely manner. Finally, if there are any other pieces of unsecured outdoor equipment, be sure to bring them inside.

Before The Storm Checklist

  1. Turn off your breakers — this includes your indoor air handler, furnace, AC system, and heat pump
  2. Turn off your gas
  3. Double check your outdoor unit, as stated above.

After The Storm Checklist

  1. Do not turn on your HVAC system immediately following the storm. First, have it inspected by a professional.
  2. Conduct a basic, preliminary inspection yourself. Look to see if your unit has experienced any external damage. If there are carbon deposits, charred metal or refrigerant leaks, the area around the unit is hazardous and you need to stay away from it.
  3. Follow this specific item-by-item safety guide provided by The Air-Conditioning, Heat and Refrigeration Institute (AHRI) following Hurricane Sandy.

When you get through several hurricane seasons without too many hiccups, it can be easy to feel increasingly lax about storm preparation. But even if the greater Jacksonville area isn’t hit directly, it is still widely susceptible to flooding, as well as both the storm and power surges that are associated with a hurricane’s outer bands. Hurricane preparation is crucial and arming yourself with knowledge is the best way to enter June this year.

If you have any other questions about maintaining or improving your HVAC system prior to the start of the 2019 hurricane season, be sure to contact us at Bold City Heating and Air today. We’ll ensure that you don’t just experience the bold difference — but the safe one as well!

Spring Is In The Air: Maintaining Indoor Air Quality

Spring Is In The Air: Maintaining Indoor Air Quality

According to the United States Environmental Protection Agency, “Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations.”

And as the spring season rolls in, so, too, do all of the allergens that can make you sniffle, sneeze, and battle your asthma.

So, what exactly can you do to ensure that you’re maintaining a healthy standard of indoor air quality? Here are our suggestions:

Regularly Clean Your Duct and Ventilation Systems

One of the most effective ways of maintaining indoor air quality is to start fresh and take whatever dust or pollutants might already be present out of circulation. Before the spring season progresses too far, you’ll want to invest in cleaning out your ventilation system, as well as your ducts. According to the National Air Duct Cleaners Association, dander, dust, and other pollutants are pulled into your HVAC system, circulated 5 to 7 times a day on average, and then become clogged in your ductwork. Cleaning those systems out regularly is key in maintaining your home’s air quality balance.

Invest In A Dehumidifier

You might not be able to control the Florida humidity outside, but the good news is that you can control the humidity in your home. When there’s too much moisture indoors, bacteria and mold are likely to grow in areas that are hidden from view, and then those particles are circulated throughout your AC system. Especially as we move from a “hot” spring to a “sweltering” summer, you’ll want to cut down on the humidity that creeps through all of the spots in your home that are in need of sealing… and a dehumidifier will help you do just that.

Schedule Your Home’s Regular HVAC Check-Up

The U.S. Department of Energy has reported that poor indoor air quality costs businesses up to $168 billion annually — but imagine what that might mean for your family’s wallet. If indoor air quality is a primary concern for you, one of the best moves you can make is to call your local professional to perform an air quality test and diagnose any preexisting HVAC problems you might otherwise be unaware of. Not only will this ensure that your home is checked through thoroughly, but you’ll know you’re walking away with a solid, long-term plan.

If you’re ready to tackle your home’s indoor air quality, call Bold City Heating and Air today to schedule an appointment! We’re here to keep your family healthy, your home safe, and to make sure you experience the bold difference, no matter the season.

Video Duct Inspections: What’s Going On Up There?

Video Duct Inspections: What’s Going On Up There?

When your ducts are out of whack, your home and health just might follow suit. After all, many Americans suffer from asthma, allergies, and other medical conditions that can be caused or exacerbated by poor air quality.

And as the Florida humidity nourishes the growth of fungus and mold during the summer, being able to effectively tackle the bacteria that might be flourishing in your house’s upper passageways isn’t just irritating—it can also be a physical challenge.

In other words, the key to maintaining your home’s indoor air quality isn’t just cleaning the ducts, it’s knowing what, specifically is going on up there.

But just how can you lay eyes on a system that is out of your immediate reach?

By turning to video duct inspections.

Video duct inspections are pretty much exactly what they sound like: it’s the process of using a camera to view and diagnose HVAC or other air quality issues inside of your home.

Not only are video duct inspections efficient in that you can use special equipment to navigate a camera around the tight angles and tricky corners throughout your entire duct system, but they’re also cost-effective!

They help you catch potential problems in the early stages, providing you the opportunity to detect and fix any issues that might have otherwise wreaked havoc on your home—and your wallet—down the line.

After all, when you can’t see it, you can’t fix it.

Video duct inspections, in particular, grant you a detailed record of images and videos that will allow you to take your health and safety back into your own hands. And what’s more empowering than knowing your own home like the back of your hand (both inside and out)?

That’s where Bold City Heating and Air comes in. By offering our expert video duct inspections, we’re here to help you take control of your home and provide you with the best HVAC service in Northeast Florida. Contact us today to schedule an appointment and experience the bold difference!

Freshen Up Your Air Conditioner: Part 2

Freshen Up Your Air Conditioner: Part 2

Last week we began covering our checklist on properly preparing your air conditioning unit for another season of battling the blistering heat of summertime in Florida. We discussed the need to keep a tidy, debris-free area outside around your unit. We also explained how to check and clean you air conditioning unit’s drain line. Finally, we stressed how easy (yet also important) it is to change your filter each month.

This week, we will cover the final items left on our pre-summer air conditioning unit checklist. Follow along and you’ll have an air conditioning system that will help you stay cool all summer long!

Discoloration is not your friend. If you look up at your central air vents and notice discoloration around them, you are looking at a condensation issue. This could be caused by air ducts that don’t have enough (or any) duct insulation. It gets hot in your attic during the summer, and air ducts that are improperly insulated allow condensation to form when the hot air in your attic comes into contact with the air ducts that are circulating cool air throughout your home. This can lead to rot and further damage to your drywall and home insulation.

Don’t block return vents.Many people make rearranging their furniture a part of their annual spring cleaning routine. Most people know that blocking air conditioning supply vents will make it tougher to cool a room down. But surprisingly, many people don’t think twice about covering or blocking the return vents. This can lead to a myriad of potential problems for your air conditioning unit. Things like frozen coils and the extra effort your unit will require to try to cool your home can lead to diminished efficiency and potential failure of your air conditioning system.

Call in the pros.The most important thing to make a part of your annual routine maintenance checklist for your home air conditioning system is to schedule a semi-annual system maintenance with one of our trained and trusted professionals from Bold City Heating and Air. We can do everything on this list and more to make sure you and your family have your coolest summer ever this year, and in the years to come.
