Understanding A/C Sizing: Why It Matters for Your Home in Tiffin, Ohio

When summer heat hits Tiffin, a working air conditioner is a must. But did you know that even a brand-new A/C system can struggle if it’s not the right size for your home? As a trusted HVAC contractor in Tiffin, Ohio, I often see comfort issues, rising energy bills, and even system breakdowns that stem from improper A/C sizing. Whether you’re noticing problems or considering an upgrade, here’s what you need to know about matching your system to your space.

Signs Your Air Conditioner Might Be Too Small

If your air conditioner is undersized, it won’t be able to keep up—especially on hot and humid Ohio days. You might notice:

• The A/C runs constantly but never reaches the set temperature.

• Hot rooms or uneven cooling throughout the house.

• Higher energy bills from overworked equipment.

• Frequent air conditioner repairs due to system strain.

  
  

These signs indicate that your A/C may not be able to handle the demands of your home.

Signs Your Air Conditioner Might Be Too Large

Yes, it’s possible to have too much cooling power. An oversized unit might seem like a good idea, but it can create comfort and efficiency issues:

• Short cycling (turning on and off too often).

• Excess humidity, making your home feel clammy.

• Uneven temperatures from room to room.

• Increased wear on parts, leading to more frequent A/C repairs.

  
  

An oversized system can lead to discomfort and higher costs, just like an undersized one.

How HVAC Sizing Works

Many homeowners assume you can size a system based on square footage alone—but there’s a lot more to it. At Greene’s, we take several factors into account when calculating the perfect size:

• Your home’s insulation, windows, and layout.

• Ceiling heights and square footage.

• Ductwork condition.

• How much sun your home gets.

• The number of people living there.

  
  

These details help our HVAC technicians in Tiffin, Ohio recommend the right system—not just a bigger one.

What to Do If You Suspect a Sizing Issue

If your A/C isn't performing well or you're facing repeat air conditioner repairs, it's time to take a closer look. Here's what you can do:

1. Schedule an A/C inspection with a qualified HVAC contractor.

2. Request a load calculation before installing a new system, specifying current issues.

3. Ask about zoning or duct upgrades for hard-to-cool spaces.

4. Keep up with maintenance to extend system life.

   
   

Taking these steps can help you identify and resolve sizing issues effectively.

The Importance of Professional Assessment

It's crucial to have a professional assess your air conditioning needs. A qualified technician can provide insights that you might overlook. They will consider all aspects of your home and lifestyle to ensure you get the right system. This is essential for maintaining comfort and efficiency.

Benefits of Proper A/C Sizing

When your air conditioner is properly sized, you can enjoy several benefits:

• Enhanced Comfort: A correctly sized unit will maintain a consistent temperature throughout your home.

• Lower Energy Bills: Efficient systems use less energy, which translates to savings on your monthly bills.

• Fewer Repairs: A well-sized unit experiences less strain, leading to fewer breakdowns and repairs.

• Longer Lifespan: Proper sizing helps extend the life of your air conditioning system.

How to Care for Your Furnace: Beginner's Guide to HVAC Care

Congratulations! You've purchased a home, filled it with furniture, and decorated the space to make it your own. It's a big step, and a life event most take great pride in. Unfortunately, homeownership doesn't come with a manual, leaving you in a tough spot when something goes wrong.

Furnaces in Ohio are typically turned on in the fall, around September and October, and are most heavily used between December and February. Whether in a new home or a house you've lived in for years, understanding how to care for your furnace is important. It can increase the life and reliability of the equipment and prevent issues with carbon monoxide, a deadly gas.

Here are the 5 areas of furnace care every homeowner needs to know:

1. Annual Maintenance - Cleaning and Servicing the Furnace Before Winter

2. Changing The Filter - Keeping the Blower Motor and Evaporator Coil Clean

3. Carbon Monoxide Alarms - The Best Safety Measure

4. Ducts & Registers - Allowing Your System To Breathe

5. Observing Operations - Sounds & Signs to Look Out For

Annual Furnace Maintenance

Regularly cleaning and servicing the furnace is a great way to keep your furnace efficient and running properly. Professional HVAC technicians will have a list of components to check and clean to prepare your furnace for heavier use during the winter. These appointments are generally less expensive than a standard service call and may even come as part of a maintenance subscription.

Changing The Furnace's Filter

Regularly changing the air filter in your ductwork is crucial to ensuring your equipment stays clean and efficient. The filter protects the blower motor and evaporator coil from getting dirty and is the easiest way to prevent damage to the furnace. Depending on lifestyle and household size, we recommend changing filters every 1 to 3 months.

Carbon Monoxide Alarms

Kidde Carbon Monoxide Alarm

Carbon Monoxide alarms, or "CO Alarms", are designed to detect carbon monoxide in the home. Carbon monoxide, or CO, is a deadly gas that has no odor or color and occurs when natural gas does not burn completely.

With any gas appliance, it's important to have CO alarms to know when the gas is present in your home. Testing these alarms and changing the batteries regularly is the best way to make sure you have the proper safety measures in place. If the alarm goes off, it's important to call an expert right away so they can find where the CO is coming from and remedy the issue.

Ducts & Registers - Letting the Furnace Breathe

Ducted HVAC Systems need adequate airflow to work properly. If ducts and registers are blocked, it can prevent the air from flowing through as easily, forcing your furnace to work harder. Check all registers in the home to be sure they are clear of objects to allow air to flow through the furnace.

Ductwork cleanings are a great way to improve airflow to the unit. We recommend clearing the ducts before having the furnace serviced due to excessive dust and dirt being kicked up from the ductwork. It's also good practice to check ductwork for any holes or damage that might inhibit airflow, too.

General Observations

Just like your wife, sometimes all a furnace needs you to do is listen. The best way to care for your HVAC equipment is to pay attention to the way it usually sounds so you can notice anything abnormal later. Looking at the unit and noting areas of corrosion, water around the unit, ice building up, or the color of the flame allows you to notice when these things change and could indicate a problem. Even the smell around your unit could help you recognize a gas leak or poor combustion.

During an annual cleaning, it can be helpful to ask your local furnace technician about any concerns they may have noticed. This way, if they notice something, you can keep tabs on it and notify them if the condition worsens (example: small hum becomes loud clanking noise).

Keeping up with these simple practices will allow your furnace to run efficiently, effectively, and for as long as possible.

Fresh Air, Fresh Start: Air Purification Solutions For Your HVAC System

As the days become warmer, there's a certain joy in the air! Springtime is wonderful for so many reasons, but some of us take the first sign of spring as a reminder to stock up on allergy meds.

As HVAC technicians, it's our job to understand air quality and how it affects the human body. If someone complains of constant congestion or frequent headaches, the symptoms could be caused by toxins or allergens in the air. These symptoms are usually a result of environmental factors, connecting air quality in the home to the health and well-being of those living there. Carbon Monoxide causes sickness and death, dust and pollen cause allergies and respiratory issues, and mold spores cause odors and general health issues (links are to sources for the facts).

Every year, we receive a multitude of questions about improving air quality. The industry is full of solutions- some excellent, some borderline scams, and most sporting big price tags. We're going to go through our list of tried and proven air quality solutions.

Air Filters: Your First Line of Defense

Heating, Ventilation, and Air Conditioning (HVAC) Filters should be changed regularly throughout the year as part of your usual home maintenance routine.

Not sure how often to change them? We've got another quick article about that here (HVAC Filters).

Your filter's main purpose is to protect your unit from building up with dust, hair, dander, and debris. By filtering out pollutants, but still allowing air to pass through, the filter keeps your HVAC equipment in optimal condition. Expensive anti-allergy filters are usually made with a thicker material because they're designed to let as little debris through as possible. They work great for collecting the gunk out of the air- so much so that they end up restricting airflow and putting stress on your unit. As a result, they need to be replaced more often because they get dirty much faster than a standard filter.

In our professional opinion, allergy-free filters are not worth it.

There are better solutions that will save you money in the long run and give the same, or better, results.

Mid-grade, light paper filters are your best bet for allergy season without breaking the bank or your unit. Change them more often during the worst parts of the season. You might also consider a reusable filter or an electric filter. Our customers have had great experiences with these options, and they're much better for your health and wallet.

Air Purifiers: The Best Air Purification Solution

Air purification is HUGE when combatting allergy season! Here are two of our favorite options and some associated prices from our experience:

AirScrubber by Aerus | $800 - $1000

AirScrubber by Aerus

By far, our favorite air purifier is the AirScrubber by Aerus. Their technology is cutting-edge, providing you with clean, oxygen-rich, allergen-free air. It eliminates odors, air-borne viruses, and mold to allow for a healthier home environment for you and your family as well.

Installation typically takes technicians an hour and requires a transformer to work properly. We estimate total costs to be between $800 and $1000 depending on area and company.

**Sometimes, Greene's runs a special, so check out our current deals!

HALO by REME | $600 - $900

HALO by REME

The next favored solution is the Halo by REME. These units will cleanse the air of any viruses, odors, allergens, and mold with the use of hydrogen peroxide. The results are not as exceptional as the AirScrubber, but it does a thorough job of purifying the air you breathe. For maintenance, the hydrogen peroxide cartridges need to be replaced every 2 or 3 years.

Installation typically takes technicians an hour, and some additional materials may be required when fitting the unit. We estimate total costs to be around $600 to $900 depending on area and company.
