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.

HVAC Service Technician: A Career Overview

As society acknowledges the labor shortage in the trades, more young individuals are exploring traditional careers like HVAC. Due to misconceptions about the value of trade careers there's a significant generational gap that exists. As highly skilled tradespeople retire with no one to fill their shoes, this wealth of knowledge and passion risk being lost.

Recently, more young people have shown interest in HVAC careers. Nate, the owner of Greene's Plumbing, Heating, and Electrical in Tiffin, Ohio, has worked in large industrial settings, fast-paced commercial projects, and residential service. He’s shared insights into the different “flavors” of HVAC service to help newcomers navigate the industry.

Residential vs Commercial vs Industrial

Residential HVAC is the most people-focused area of the industry. Technicians often work directly with homeowners, who personally cover service costs. This means emotional intelligence, patience, and strong soft skills are essential. Projects typically range from an hour to a few days, offering a high variety of tasks and projects. For those who get bored with repetition and enjoy problem-solving, residential HVAC is a great fit. At Greene’s, we’ve found residential service particularly rewarding because it allows technicians to take pride in delivering quality work and ensuring homeowners are comfortable and safe.

Commercial HVAC serves small businesses to large corporations. Our experience includes restaurants, commercial kitchens, and laundromats. This field offers a balance between variety and repetition, as projects can last from several days to several months. While technicians might not interact directly with the end-user, there’s a focus on efficiency and teamwork. The environment can feel more task-oriented, though it’s an excellent fit for those who prefer structured projects and steady workflows. Opportunities to specialize and advance into roles like system design or project management are also more common.

Industrial HVAC involves large-scale systems in factories and plants. This area requires specific certifications and strict adherence to safety standards due to complex environments. Technicians often work on heavy-duty equipment, and while there’s less focus on the end-user, the scale and technical challenges can be highly rewarding. Industrial HVAC is perfect for those who enjoy working with complex systems and want to develop niche expertise.

Job Security of HVAC Service Technicians

Job security in HVAC is strong across all sectors, though it does vary slightly.

• Residential HVAC offers high job security. Homeowners consistently need climate control, regardless of economic shifts, due to health and safety concerns. While demand can fluctuate seasonally, there’s always work to be done.

• Commercial HVAC can be more sensitive to economic changes. New construction and large projects may slow during downturns, but maintenance and repairs continue to offer steady work. For those who enjoy larger-scale projects that allow for a more repetitive and predictable work day, commercial offers stability with room for growth.

• Industrial HVAC is often the most stable, especially when working with large factories or plants that require constant climate control (though it can be more susceptible to major economic movement than residential). While economic downturns can impact this sector, many industrial facilities maintain their HVAC systems year-round, providing consistent work.

Finding Your Fit

Each area of HVAC offers unique challenges and rewards. Residential is ideal for those passionate about quality craftsmanship and customer satisfaction. Commercial provides a fast-paced environment with opportunities to specialize. Industrial offers complex, large-scale projects for those who love technical challenges.

At Greene’s, we’ve found residential HVAC to be the most fulfilling for technicians who take pride in their work and enjoy creating a positive experience for homeowners. But every path has value, and finding the right fit depends on your interests, strengths, and career goals.

No matter which direction you choose, HVAC is a stable, rewarding career with plenty of opportunities to grow and make a difference.

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.
