Getting to Know Your HVAC: A Quick Overview

Okay, let’s get a little more technical. Before you start tinkering with anything, it’s a good idea to understand the main players in your home’s comfort system:

1. Heating: Your furnace (usually gas-powered), heat pump (electric and can also cool), or boiler (water-based) are your winter warriors. They keep you cozy when the temperatures drop. Furnace repair is one of the most common HVAC services.
2. Cooling: Your central air conditioner or the cooling mode of your heat pump is your summer savior, battling the Arizona heat. AC repair is essential for surviving those scorching months.
3. Ventilation: The unsung hero! Your ducts and vents circulate the air, ensuring even heating and cooling, filtering out dust and allergens, and controlling humidity levels.

Different Types of HVAC Systems

Think of HVAC systems like people – they come in different types with unique quirks:

• Split systems: The most common type, with an indoor unit (usually your furnace or air handler) and an outdoor unit (your AC or heat pump).
• Packaged systems: All components are housed in one unit outdoors.
• Ductless mini-split systems: Great for individual rooms or additions, without the need for ductwork.

No matter what type of system you have, regular HVAC maintenance is key to keeping it running smoothly and efficiently. It’s like getting an oil change for your car – a little preventative care can save you from a major breakdown down the road.

It may interest you to know that a well-maintained HVAC system can help you to save on your energy bills. That’s right! In this way, you can save energy and have lower monthly bills if you maintain the cleanliness of your system.

DIY HVAC Tune-Ups

Okay, let’s get down to business! Of course, some HVAC repairs are best left to the professionals (like the good people at Morehart AC & Heating), but there are a few things that you can do yourself to keep your system running smoothly and maybe even save a little money in the process.

Easy Fixes for a Happy HVAC System

1. Air filter

Your air filter is the lungs of your HVAC system. If it is filled with dust and other materials, then your system will have to struggle and this will result to high electricity bills and system failure. Fortunately, it is very easy to change – you just need to find the filter slot (it is often located behind a panel of your indoor unit), remove the old one, and insert a new one of the same size and type. Ideally, it should be replaced every 1-3 months, depending on the type of filter and the amount of dust in your home.

2. Thermostat troubles

Is your thermostat behaving erratically? It may be as simple as checking the batteries again! If that doesn’t work, try changing the temperature settings to see if it helps to solve the problem. However, if your current thermostat is old or is always giving you a hard time, then it is high time you consider upgrading it. Morehart AC & Heating can assist you in selecting a new thermostat that will work with your system and your lifestyle.

3. Dust bunnies

Grab your trusty vacuum cleaner and give your vents and registers a good cleaning. This will help improve airflow and prevent dust from circulating throughout your home. While you’re at it, take a peek at your outdoor unit. Clear away any debris, leaves, or overgrown plants that could be obstructing airflow.

4. Drip Drop

If you notice any water pooling around your indoor unit, it could be a sign of a clogged condensate drain line. This line carries away excess moisture from your air conditioner or heat pump. Clearing it out is usually a simple fix – just flush the line with a mixture of water and bleach or use a wet/dry vacuum to suck out any blockage.

A Word of Caution

Remember, DIY repairs are best for minor issues. If you’re dealing with more complex problems like refrigerant leaks, electrical issues, or major component failures, it’s always best to call in the experts. Morehart AC & Heating has the knowledge, experience, and craftsmanship to handle any HVAC repair, big or small. Plus, we use only the highest quality parts and materials from reputable brands to ensure your system is running at peak performance.

So, go ahead and give those simple fixes a try! But if you’re ever in doubt, don’t hesitate to reach out to Morehart. We’re always happy to lend a helping hand (or wrench!) to keep your home comfortable all year round.

Basic Troubleshooting

Now that you’ve got the basics of HVAC maintenance down, let’s tackle some common problems you might encounter with your system. Remember, these tips are for minor hiccups – if things get too complicated or you’re unsure, it’s always best to call in the experts at Morehart AC & Heating.

Scenario 1: Your AC is Blowing Hot Air (Not Cool!)

The Arizona heat is brutal enough without your AC turning on you! If your air conditioner is blowing hot air instead of cool relief, don’t panic. There are a few common culprits you can check yourself before calling in the pros:

• Thermostat: First things first, make sure your thermostat is set to “cool” and the temperature is set a few degrees lower than the current room temperature. It sounds obvious, but you’d be surprised how often a simple setting adjustment does the trick!
• Filter: A dirty air filter is a common cause of AC woes. It’s like trying to breathe through a straw – your system has to work harder, and it just can’t keep up with the demand for cool air. Swap out that dirty filter for a fresh one and see if that makes a difference.
• Refrigerant: If your AC is low on refrigerant (the stuff that makes the cooling magic happen), it won’t be able to do its job. Unfortunately, this isn’t something you can fix yourself. If you suspect a refrigerant leak, call in the experts at Morehart AC & Heating to diagnose and repair the problem.
• Breaker: Before you call anyone, double-check your electrical panel. If the breaker for your HVAC system has tripped, simply reset it. Easy peasy!
• Condenser Coil: The outdoor unit’s condenser coils can get pretty grimy, especially in our dusty desert climate. This buildup can prevent the coils from releasing heat, causing your AC to struggle. Gently hose off the coils (remember to turn off the power first!) and see if that improves things.

Scenario 2: Your Furnace is Giving You the Cold Shoulder

Brrr, a cold house in the winter is no fun! If your furnace isn’t producing any heat, here are a few things to investigate before calling in the cavalry:

• Thermostat (again!): Just like with your AC, make sure your thermostat is set to “heat” and the temperature is set a few degrees higher than the current room temperature.
• Pilot light problems (gas furnaces only): If your furnace has a pilot light, make sure it’s lit. If it’s out, try relighting it according to the instructions on your furnace. Still no luck? Call Morehart AC & Heating – it could be a gas supply issue or a problem with the thermocouple.
• Filter: Yep, that pesky air filter can cause problems with your heating too. A clogged filter restricts airflow, making it harder for your furnace to do its job. Swap it out for a new one and see if that helps.
• Gas gauge: If you have a gas furnace, make sure the gas valve is open. If it’s closed, your furnace won’t have any fuel to burn.
• The flame: Take a peek at the furnace flame (if it’s safe to do so). If it’s weak, uneven, or flickering, it could indicate a problem with the burners or gas pressure. This is another situation where it’s best to call in the professionals.

Scenario 3: Weird Noises From Your HVAC Unit

If your HVAC system starts sounding like a scene from a horror movie, it’s definitely time to investigate. Those creaks, groans, and bangs could be trying to tell you something important. Here’s a breakdown of some common HVAC noises and what they might mean:

• Rattling: This usually means something’s loose. It could be a screw that needs tightening, a panel that’s come undone, or even debris rattling around in your ductwork. If you’re feeling adventurous, you can try to locate and tighten any loose screws yourself. Just be careful not to overtighten them! If the rattling is coming from inside the ductwork, it’s best to call in a professional to investigate.
• Squealing: This high-pitched noise often indicates a worn-out belt or bearing. These components are essential for the smooth operation of your system, so it’s important to address this issue promptly. Unfortunately, replacing belts or bearings usually requires specialized tools and expertise, so it’s best to leave this repair to the pros at Morehart AC & Heating.
• Grinding: A grinding noise is often a sign of trouble with your HVAC motor. It could mean the bearings are worn out, the motor is overloaded, or there’s another mechanical issue. This is definitely not a DIY repair – call in the experts to diagnose and fix the problem before it causes further damage.

Remember, safety first! If you’re not comfortable working with electrical or mechanical components, don’t attempt any repairs yourself. Call Morehart AC & Heating and let our experienced technicians handle it for you.

Scenario 4: Your Energy Bills Are Sky-High

Unlike a noisy HVAC unit, high energy bills might not be immediately obvious. But they can sneak up on you, draining your wallet month after month. Here’s what could be causing those bills to soar and how you can take action:

• Inefficient system: If your HVAC system is older or outdated, it might simply be less efficient than newer models. The technology has come a long way in recent years, with more energy-efficient compressors, motors, and fans. If your system is nearing the end of its lifespan, it might be time to consider an upgrade. Morehart AC & Heating can help you choose a new system that fits your budget and saves you money on energy costs.
• Dirty air filter (The Usual Suspect): Yep, we’re back to the air filter again. It’s amazing how much impact this small component can have on your energy bills. A clogged filter forces your system to work harder, consuming more energy and driving up your costs. So, make sure you’re changing your filter regularly according to the manufacturer’s recommendations.
• Leaky ductwork: Your ductwork is like the circulatory system of your HVAC system, delivering conditioned air to every room in your home. If there are leaks in your ducts, you’re essentially paying to heat or cool the attic or crawl space. Have your ducts inspected and sealed if necessary to prevent energy waste.

DIY Energy-Saving Tips

• Smart thermostat: Investing in a programmable or smart thermostat can be a game-changer for your energy bills. These thermostats allow you to create custom schedules and adjust the temperature remotely, so you’re not wasting energy when you’re not home.
• Regular maintenance: Proper HVAC maintenance is essential for optimal performance and energy efficiency. Schedule regular tune-ups with Morehart AC & Heating to keep your system running smoothly and catch any potential problems early on.
• Proper insulation: Make sure your home is properly insulated to prevent heat loss in the winter and heat gain in the summer. This will reduce the strain on your HVAC system and help you save on energy costs.

When Your DIY Skills Just Won’t Cut It

Listen, we’re all for empowering homeowners to tackle minor HVAC fixes. But there comes a time when you need to wave the white flag and call in the pros. Here are a few signs that it’s time to call Morehart AC & Heating for backup:

• Burning smell: If you smell something burning coming from your HVAC unit, turn it off immediately and call Morehart. This could indicate an electrical problem or a motor that’s overheating.
• Noises that go bump in the night (and day): While some noises are normal, persistent or unusual sounds (think grinding, screeching, or banging) could mean serious trouble. Don’t ignore these warning signs – call in the pros to investigate.
• Refrigerant leaks: Refrigerant is the lifeblood of your AC system, and leaks can be dangerous and harmful to the environment. If you suspect a leak, leave it to the professionals at Morehart AC & Heating to fix it safely and responsibly.
