The Importance of HVAC Maintenance

Because it maintains the comfort of our homes, HVAC systems are important but often taken for granted. To prolong your HVAC system’s life, you need to maintain it. It works alongside the thermostat and central heat system, so if one fails, the others will follow. 

Maintaining your HVAC system means regular checkups, cleaning, and quickly repairing faulty parts. But many other things can help keep the HVAC system functioning properly! 

This article will elaborate on the importance of HVAC maintenance, how it works, and what the benefits are in the long run. 

What Is HVAC Maintenance?

HVAC is an acronym encompassing the heating, ventilation, and air conditioning processes. The term combines all the appliances you use to control the home or office temperature. This complex system cleans the air and maintains the humidity at optimal, healthy levels. 

HVAC systems have to be fully functional throughout the year. Keeping the right temperature levels and stale air requires work; hence a maintained and operating system is a must. But what is HVAC maintenance and what obstacles you may encounter?

Some problems HVAC maintenance teams come across in these systems are dirt particles stuck on the heating coils, dirt around the condensate unit, debris collected in the blower, an outdated thermostat, and too little or too much refrigerant. 

Maintenance also involves repairing parts that break. This usually concerns the interior components of the furnace or air conditioner. Maintenance is preferable before the summer and winter sessions, meaning at least two times a year. 

What Does HVAC Maintenance Include

The lifespan of the HVAC system depends on regular maintenance. Disregarding the care may lead to a malfunctioning HVAC system and an extremely hot or freezing house. Sometimes the cleaning you do yourself isn’t enough to desensitize every part. You will need to call professionals who know what a routine HVAC maintenance procedure involves.

Let’s take a closer look at what does HVAC maintenance include.

Inspecting the Functionality of the Thermostat 

A faulty thermostat can create a hotter or cooler home than usual. If temperatures in the rooms change often, you should check if the thermostat works. 

Checking the Connections

Check the heating elements and their connections. These can cause many headaches, and they are your first indicator that something might be wrong. They are also the most dangerous parts of the system that always need monitoring. Keeping the heating elements connections clean and unblemished is imperative to an HVAC system. 

Examining the Motor Operations 

Maintaining a clean blower helps maintain proper and clean airflow. If you notice that your AC is running low and you don’t feel a change in temperature when you leave or enter your home, there might be something wrong with motor commands. Wire damage or electric leakage may be the cause of this. 

Thorough Cleanups of Coils And Condenser  

The coils and condenser are parts that require continuous cleaning. Dust usually collects around the evaporator coils and the condenser, which could hinder them from working efficiently. They keep the HVAC system running smoothly. 

Clean these parts once a year unless you live in a big city with highly polluted air. If that’s the case, clean them twice a year before summer or winter starts. The same is applicable for those who use their AC 24/7, all year round. 

Monitoring Refrigerant Pressures 

Your HVAC system needs a specific quantity of refrigerant. Keeping the refrigerant at optimal levels will have the system running smoothly. Too much refrigerant means the HVAC system cannot cool down your home efficiently. 

The reason is that the refrigerant switches from gas to liquid state. If the refrigerant remains in a liquid state, it warms the system and hinders cooling.

The Most Important Things to Know About HVAC Maintenance

Usually, what is done during HVAC Maintenance and cleanups is hosing down the entire system. Inspect every part for damage or dirt, including every coil, duct, filter, fan, and refrigerant. 

A maintenance check-up also inspects whether the motors are working fine and the connections are stable. Preparing the HVAC systems for the winter and summer seasons should be part of the routine. This twice-a-year cleaning habit will maintain the HVAC system in tip-top shape.

Cleaning the HVAC system is not a “one man’s job” because it requires precision. Sometimes the wise thing is to call professionals. 

DIY HVAC Maintenance: Is it a Good Idea?

The recommendation is always to leave the maintenance of HVAC systems to professionals. However, you can do some of the simpler tasks yourself! Here are a few tips on DIY HVAC maintenance, so you’ll know what to expect.

Cleaning Outdoor Units Together With Indoor Ones 

Many people forget that cleaning the debris from the outdoor unit prolongs the efficient working of the indoor ones. The key to proper HVAC repair and maintenance is looking into every component, indoors or outdoors. 

Outdoor units are a target of all kinds of debris, like leaves, dirt, and dust. All these particles can hinder the functioning of the HVAC system, so get your gloves and hose. Remove the cage or fan to clean every inch of the outdoor unit better. A clean outdoor unit means smoother indoor airflow. 

Don’t Overuse the AC 

Many prefer the cool temperatures the AC provides, but the ceiling and portable fans can do the same job. You don’t have to power your AC if it’s not scorching outside. All fans, whether portable or ceiling, do a fantastic job of lowering the temperature of a room. 

Sometimes, even opening your windows can do a lot for indoor airflow. The point is to refrain from using the AC unless absolutely necessary. It will prolong its lifespan and help save on the bills in the long run. 

Monitor the Evaporator Coil and Condensate Drain

The evaporator coil is what keeps you cool during scorching summer days. Its job is to absorb the heat, cool it, and then release it inside the house. Evaporator coils are very important to the HVAC system because they condense the air humidity to water during the cooling process. The condensed water then exits through the condensate drain. 

Monitor the condensate drain, as over time it can get clogged with mud, mold, or algae. The system’s drainage is vital and it’s a good idea to check it often. 

Inspect the Air Filters 

The top suggestion for spotless DIY HVAC maintenance tips is keeping your air filters clean. It’s easy and beneficial because you allow other components to work efficiently. If the filters are dirty, you are risking the malfunctioning of the whole HVAC system. The airflow restriction is the reason for this, making the blower motor work twice as hard. 

An overworked blower motor can die faster than expected. Lots of debris gets caught up in the filters, hindering the whole cooling or heating process. A new filter guarantees cleanliness in your air, with no bacteria or particles. 

Turn Off the Humidifier 

The funny thing about humidifiers is that most furnaces use one. These humidifiers don’t need to be working all the time. Once summer hits, try to turn off the water supply in your furnace and allow the humidifier to rest. 

When the cool weather returns, reduce the humidity back to 35-45% and turn on the water supply.  Also, replace the humidifier pad with a new one to avoid collecting bacteria. 

Clean Registers and Ducts 

Keep the registers and ducts squeaky clean for your HVAC system to continue functioning smoothly. Registers are a breeding ground for all kinds of gunk and bacteria, so put gloves on and get to detailed cleaning. 

The air ducts attract the most dust, and keeping them clean will guarantee the longevity of your heating system. This means fewer allergens, and you can usually clean the ducts using your home vacuum. Wipe down the registers once you finish. 

Reach Out to Professionals

Although you would do a fantastic job cleaning and maintaining your HVAC, sometimes the processes could be more detailed and complex and require an expert’s touch. For example, only a professional knows how to get your air ducts 100% clean.

5 Tips For Maintaining Your HVAC System

The HVAC System is one of the most important parts of your home, especially here in Arizona! It’s essential to keep your HVAC system properly maintained. By doing so, you’ll prolong its life, save money on energy bills, and ensure that your home or business is always comfortable and cool.

A Professional Heating and Cooling expert will be able to help inspect, repair or replace your HVAC System when needed. However, there are a few things each Homeowner can do to help keep their AC Running Smoothly.  By following these simple tips, you can maintain your HVAC system and keep it operating at its peak efficiency for years to come. Here are 5 tips on how to maintain your HVAC system: 

1. Change your air filter regularly.

 A dirty air filter can make your system work harder than it needs to, which can lead to premature wear and tear. This will reduce airflow and put a strain on your HVAC system. Your HVAC System is already working hard in the hot months of June, July, and August, you don’t want to put additional strains on it that you can prevent. A dirty air filter will also circulate dirt, dust, dander, and allergens through your home and put your family at risk. Changing your air filter with each system is an effective and affordable way to help maintain your HVAC System.

2. Keep your HVAC System Clean.

One of the most important things you can do to maintain your HVAC system is to keep it clean from dust, dirt, and debris that can clog up the system and make it less efficient. Leaves, dirt, and other debris can also block airflow and cause your HVAC system to work harder than necessary. Give your HVAC a helping hand and remove any debris that could be damaging it or decreasing its efficiency.

3. Inspect your ductwork regularly.

Another important maintenance task is to inspect your HVAC System and Ductwork regularly.  Inspecting your ductwork regularly can help you spot any leaks or damage that would need to be addressed by a professional. Leaks can develop in an HVAC System over time and cause your HVAC system to work harder than it needs to, which leads to higher energy bills. If you find any damage or leaks, be sure to have it repaired as soon as possible.

4. Schedule regular maintenance checks with a professional. 

One of the best ways to maintain your HVAC system is to schedule regular maintenance with a qualified technician. This will ensure that your system is running properly and can help prevent future problems. A professional HVAC technician can identify potential problems and prevent them from becoming major issues! It’s recommended to have your HVAC System inspected by a trusted professional once a year at a minimum. 

5. Know when to call for help.

While your HVAC system is a crucial element in maintaining your home’s comfort, it’s not the only component that requires attention. Being attuned to signs of trouble in other areas of your home can help prevent issues from escalating. Here are some common problems homeowners may encounter:

a. Unusual Noises: If you hear strange sounds emanating from your HVAC system, it could signal a problem. Similarly, when you notice your roof creaking or your windows rattling, it’s time to take action.

b. Peculiar Smells: Unpleasant odors wafting from your HVAC system or elsewhere in your home are indicators of potential issues. Don’t ignore these scents, as they could signify problems with insulation, plumbing, or even pests.

c. Roof Issues: To maintain the structural integrity of your home, schedule regular roof inspections. Leaky roofs or damaged shingles can lead to more extensive and costly repairs if left unattended.

d. Insulation Concerns: Proper insulation is vital for energy efficiency. An inspection can identify inadequate insulation, which can result in increased energy bills and decreased comfort.

e. Window Problems: Inspect your windows for signs of damage or poor sealing. Drafty windows can affect temperature control and energy efficiency in your home.

Addressing these common issues promptly with the help of trained and certified professionals can prevent larger problems and ensure that your home remains a comfortable and efficient sanctuary. Whether it’s your HVAC system, roof, insulation, windows, or other components, investing in regular inspections and timely repairs will keep your home in its best condition.

How To Keep Your Air Conditioning Running Smoothly This Summer

With temperatures rising above 100 degrees in Tucson, let’s talk about something every homeowner has on their mind: how to keep their air conditioning unit running properly for the season!

While Arizona is known for having year-round heat, the hottest months of the year such as May, June, July, and August are when your air conditioner will see the most action. You will need to run your HVAC around the clock to keep your home or business comfortable and cool during the summer and the last thing you want is your HVAC to break or not function properly when it’s scorching outside.

The best way to maintain your A/C is by getting it inspected regularly, keeping up with the recommended maintenance, and hiring trusted experts when the time comes for Repairs or Replacements!

How To Maintain Your Air Conditioning System

An HVAC system is one of the most essential components of a house, especially for households located in extreme climates such as Arizona.

You’ll want to get your HVAC unit inspected to ensure all parts are functioning as they should be, especially before summer begins. There are a lot of components and a specialist can analyze your unit to make sure it’s in tip-top shape.

One of the most basic steps you can take to maintain your HVAC system is to always keep the unit clean, both inside and out. Homeowners will want to ensure that there is no buildup or debris on the outside of the unit, such as dirt or leaves. You can also hire professionals to clean inside the Air Vents to keep it running smoothly.

You will also need to change the filter on your AC regularly, at least every three months or when the seasons change. A new filter can drastically improve the air quality inside your home and help your unit run efficiently.

What Happens if Your Air Conditioner Isn’t Working

An Air Conditioning System failing during summer is every homeowner’s nightmare. It’s hot and you, your family, and your pets need a comfortable and cool environment. Don’t wait until the problem gets worse!

If it feels hot in your house, check to make sure the thermostat is set to Air Conditioning Mode. If it’s three or more degrees warmer in your home than your thermostat is set to and the air conditioning isn’t working, call a trusted company to inspect the unit.

There are other warning signs to watch out for that can indicate your HVAC isn’t working efficiently. Common problems you may be experiencing with your air conditioning unit include:

  • AC Not Turning On
  • No Cool Air Flowing
  • Hot Air Blowing Out
  • Water Leaking
  • Unit Turning On and Off Repeatedly
  • Strange Smells Coming From System

Some common components that may cause these issues include the power source, the thermostat, refrigerant levels, evaporative coils, ducts, drainage systems, or fans. We suggest you do not try to fix your AC unit yourself to keep yourself safe and avoid causing further damage to your AC unit and your home.

How To Fix a Broken AC Unit

 Air conditioners have a lot of moving parts that work together to make them run smoothly, so if your air conditioner stops working, the best thing to do is to call a licensed professional to see if your air conditioner can be repaired before you start worrying about replacing the entire unit.
