Schedule Your Furnace Tune Up Before Cold Weather Hits

As the cooler air starts to roll in, your furnace becomes one of the most relied-on systems in your home. Without regular care, even the most reliable units can become inefficient or fail unexpectedly—usually right when you need them most. Early furnace tune up service from Postma ensures your system is ready for the months ahead and helps prevent mid-season breakdowns.

What’s Included in a Professional Furnace Tune Up?

A typical tune up includes a complete inspection of your furnace’s internal components—cleaning burners, testing ignition systems, inspecting the heat exchanger, and replacing or cleaning the air filter. At Postma, our technicians also check for potential safety hazards like gas leaks or carbon monoxide, and make sure your thermostat and airflow are working properly.

Carrier emphasizes that routine furnace tune ups help maintain performance, improve air quality, and reduce the risk of unexpected repairs. Keeping your system in peak condition ensures consistent comfort during the coldest months.

How a Tune Up Can Lower Heating Costs

When your furnace isn’t tuned up regularly, it has to work harder to heat your home. Dust buildup, clogged filters, and worn parts reduce efficiency and drive up energy bills. Regular service helps your furnace run smoothly and keeps costs under control. According to Bryant, proper tune ups not only lower energy usage but also extend the life of your system—saving you from premature replPostma HVAC technician performing furnace maintenance, using tools to service internal components of a residential heating unit inside a utility room.acements.

Why You Should Book Early

Once temperatures drop, HVAC companies across Ontario fill up fast with emergency repair calls. Booking your furnace tune up now ensures a convenient time slot and gives technicians time to identify and fix any issues before winter fully sets in.

Early Warning Signs Your Furnace May Need Service

Strange noises, uneven heating, short cycling, or higher-than-normal bills may be signs your furnace needs a tune up. Even without obvious symptoms, regular service is essential to catch small problems before they become big, expensive ones.

How Tune Ups Help Your Furnace Last Longer

A well-maintained furnace can last 15 to 20 years, but neglecting annual tune ups puts extra strain on your system. Over time, this wear and tear can cause premature failure. Keeping up with scheduled service protects your investment and ensures long-term reliability.

Heat Pump Installation in Chatham-Kent

Looking for a smarter, more efficient way to heat and cool your home in Chatham-Kent, St. Thomas, Windsor, or Sarnia? A properly installed heat pump provides year-round comfort and serious energy savings — especially when installed by the trusted experts at Postma Heating, Cooling, Plumbing and Electrical. Whether you’re ready to replace your air conditioner or want to take the next step for energy efficiency and head straight to a new heat pump installation, Postma can help.


🔥 What Is a Heat Pump?

A heat pump is a dual-purpose HVAC system that both heats and cools your home by transferring heat, not generating it. In winter, it extracts heat from the outdoor air to warm your home. In summer, it removes indoor heat and pushes it outside — just like an air conditioner.

Modern heat pumps, especially cold-climate models, work efficiently even in -25°C, making them ideal for Southern Ontario homeowners.


✅ Why Choose a Heat Pump?

✔️ Year-Round Efficiency

Keep your home cool in summer and warm in winter.

✔️ Lower Monthly Bills

Heat pumps can cut heating energy use by up to 60%, especially compared to electric baseboards or older systems.

✔️ Environmentally Friendly

They run on electricity and produce no on-site carbon emissions, supporting a cleaner future.


💸 Heat Pump Installation Costs in Southwestern Ontario

System Type Installed Cost (CAD) Best For
Air-source heat pump $4,000 – $9,000 Most residential homes
Cold-climate heat pump $6,000 – $12,000 Reliable in freezing conditions

Technician from Postma Heating, Cooling, Plumbing and Electrical performing a $99 AC tune-up on an outdoor air conditioning unit, including full system inspection and preventative maintenance to improve cooling efficiency, reduce breakdowns, and prevent AC not cooling issues in summer.

Why Is My AC Not Cooling?

When summer heat sets in, nothing is more frustrating than an AC not cooling when you need it most. Every year, Postma Heating, Cooling, Plumbing and Electrical gets a wave of service calls from homeowners with the same complaint: the air conditioner is running, but the air coming out is warm.

One of the leading causes? A small but essential component called the capacitor.


The Role of a Capacitor in Cooling Your Home

The capacitor works like a burst of stored energy for your AC’s motors. There are two main types:

  • Start capacitors – Give the compressor the power surge it needs to start running.

  • Run capacitors – Keep the motor running smoothly through the cooling cycle.

When a capacitor fails, your AC may hum but never start, shut off unexpectedly, or simply blow warm air. That’s when you end up with an AC not cooling right in the middle of a heatwave.


Why Summer Heat Triggers More AC Problems

Hot, humid summer weather puts extreme stress on air conditioning systems. Capacitor failures spike during this season because of:

  1. Heat stress – High outdoor temperatures cause internal components to overheat and wear out faster.

  2. Heavy workload – Long cooling cycles mean capacitors are charging and discharging constantly.

  3. Age – Capacitors generally last 5–10 years, and older ones are more likely to fail under pressure.

According to the U.S. Department of Energy’s guide to common AC problems, regular maintenance is key to preventing these situations by spotting worn parts before they break.


Signs Your AC May Have a Failing Capacitor

If your air conditioner is blowing warm air or taking too long to start, the capacitor might be to blame. Watch for these signs:

  • Weak or no airflow from vents

  • AC shuts off randomly during operation

  • Humming sound from the outdoor unit

  • Bulging or leaking capacitor casing

  • Burning smell near the outdoor unit

Any of these symptoms can lead to an AC not cooling — and running the system in this condition risks damaging the compressor.


How to Prevent Mid-Summer Breakdowns

Customer review praising Postma Heating, Cooling, Plumbing and Electrical technician Kyle L. for friendly, professional preventative AC maintenance service, explaining the air conditioner maintenance plan clearly with no pressure and earning a strong recommendation.

While capacitors will eventually wear out, you can lower the chances of an AC emergency by:

  • Scheduling annual AC maintenance in spring

  • Keeping the outdoor condenser free from dirt and debris

  • Avoiding sudden thermostat drops during extreme heat

  • Replacing older capacitors before peak cooling season


Other Reasons an AC Might Not Be Cooling

Not all cooling problems are caused by capacitors. Your system could also be struggling due to:

  • Low refrigerant from a leak

  • Dirty evaporator or condenser coils

  • Clogged air filter

  • Faulty thermostat

  • Compressor issues

Carrier’s troubleshooting guide for AC not working highlights that airflow restrictions, electrical faults, and sensor problems can also cause poor cooling performance.

Only a certified HVAC technician can confirm the cause of an AC not cooling and recommend the right repair.


Get Your Cool Back Fast

If your AC is not cooling, don’t wait for the problem to get worse. Capacitor failures are one of the most common issues we see every summer, but quick action can save you from costly repairs.

Whether you’re in Chatham-Kent or the surrounding area, Postma Heating, Cooling, Plumbing and Electrical can get your system running at full power again so you can enjoy a cool, comfortable home all summer long.

Postma HVAC technician in Chatham-Kent programming a smart thermostat to resolve heating and cooling issues and improve home energy efficiency.

How to Troubleshoot Thermostat Issues Before You Call the HVAC Pros

When your heating or cooling system isn’t doing what it should, it’s easy to assume the furnace or air conditioner is to blame. But more often than you might think, it’s a thermostat acting up. A few simple steps could help you figure things out—and possibly avoid a service call. At Postma Heating Cooling Plumbing and Electrical, we always recommend ruling out the basics before reaching for the phone.

Check the Thermostat Display and Power Source

Start by looking at the display. If the screen is blank or not responding, it could be as simple as drained batteries. Most battery-powered thermostats need a change once a year. For hardwired or smart thermostats, make sure they’re getting power, especially if you’ve recently had electrical work or a power outage.

Some smart thermostats, like Ecobee or Nest, need a constant flow of power and won’t work correctly without a common (C) wire. That’s something not all older homes are set up for. If you’re unsure how your thermostat gets its power, it’s a good idea to understand the basics of smart home wiring. The Electrical Safety Authority offers helpful info about wiring safely for smart technology in Ontario homes.

Double Check the Settings

It seems obvious, but it’s worth confirming the thermostat is set to the right mode—heating, cooling, or auto—and that the temperature is actually high or low enough to trigger the system. It’s common for someone to accidentally switch modes or change the schedule without realizing it. A quick adjustment might be all it takes.

Look at the Breaker Panel

If your system still won’t turn on, head over to your home’s electrical panel. A tripped breaker can cut power to your HVAC equipment or thermostat, causing it to stop responding. Flip the breaker fully off, then back on to reset it. If it trips again, it’s best to get that looked at by a licensed professional.

Give It a Gentle Clean

Thermostats can collect dust and grime over time, especially older mechanical models. Carefully remove the front cover and gently wipe around the sensors and buttons with a dry cloth. Avoid using any liquid cleaners or compressed air, as those can damage the internal components.

Review Smart Thermostat Settings

If you have a smart thermostat, open the app and check your settings. Things like disconnected Wi-Fi, outdated firmware, or a misconfigured schedule can all prevent your system from running. A quick reboot or re-connection can sometimes solve the issue.

Thinking about upgrading to a smart thermostat? The federal government may cover part of the cost under the Canada Greener Homes Initiative, which includes rebates for eligible smart home improvements.

Safely Test a Bypass (Only If You Know How)

If you’re confident working with low-voltage wiring, you can try a manual test. Turn off power to the system, remove the thermostat from the wall, and briefly connect the R (power) and W (heat) wires. If the furnace kicks on, the thermostat is likely the issue. This isn’t for everyone, so if you’re unsure, skip it and give us a call.

When It’s Time to Call Postma

If none of these steps fix the problem, it’s time to bring in the experts. Whether it’s the thermostat or something more complex like your HVAC system, our trained professionals at Postma will find the solution quickly and safely. We’ve been proudly serving Chatham-Kent for over 35 years, with honest service and dependable results that give you peace of mind.

Why Air Conditioning Services Matter

Summers in Chatham‑Kent and the surrounding areas can be hot and humid, and keeping a home comfortable depends on a well‑designed air‑conditioning system. For homeowners and business owners looking for expert air conditioning services in our community, a proactive approach is essential. As a mechanical contractor working with clients across Chatham‑Kent and southwestern Ontario, Postma Heating, Cooling, Plumbing and Electrical sees a common theme—people wait for their system to break before thinking about maintenance. In reality, the cost of ownership is driven by energy efficiency. Air‑conditioners account for a significant portion of household electricity use, so investing in regular service and strategic upgrades not only lowers utility bills but also prolongs equipment life.

Why preventive maintenance matters

It’s easy to forget about your HVAC equipment when it’s tucked away in the basement or outside. However, a neglected air‑conditioner loses efficiency each season as filters clog, coils get dirty and refrigerant levels drift. Natural Resources Canada (NRCan) recommends keeping your system clean and changing filters regularly; dirty filters and coils force the system to work harder, increasing energy consumption. Beyond cleaning, professional technicians will tighten electrical connections, lubricate moving parts and inspect condensate drains to prevent water damage.

According to Hydro One’s energy guide, heating and cooling account for roughly 65% of a typical home’s energy costs. Simple steps like sealing air leaks around windows and doors can reduce heating and cooling needs by up to 20%, while using a programmable thermostat can cut energy use by about 10%. These low‑cost actions go hand‑in‑hand with professional maintenance; a tune‑up ensures that your air‑conditioner delivers the comfort you pay for rather than wasting electricity.

When to consider replacing your AC Graphic featuring a customer review for Postma Heating & Cooling, Electrical, and Plumbing. A blue speech bubble contains a five-star rating and the review: “Today Kyle L visited our home for a AC checkup. He was thorough, polite and very informative. You have great employees!” — Mary M. The background shows a smartphone with the Postma logo and the tagline “Experts You Can Trust.”

If your current central air‑conditioner or heat‑pump is more than a decade old, it might be cheaper in the long run to replace it. NRCan notes that upgrading to an ENERGY STAR certified central air‑conditioner can save “upwards of 20%” in energy compared with an older model. Newer systems are quieter, more reliable and use less energy. Other signs that it’s time to upgrade include major component failures, frequent service calls and unusual noise during operation.

As an HVAC contractor, we often recommend high‑efficiency variable‑speed systems because they modulate output based on demand. They maintain more consistent temperatures and humidity, which improves indoor air quality and reduces wear on components. When paired with smart thermostats and zoning controls, these systems can trim energy consumption even further.

Take advantage of energy programs

Homeowners in Chatham‑Kent and southwestern Ontario don’t have to shoulder the cost of energy savings alone. For example, the Save On Energy CoolSaver program provides free tune‑ups for central air‑conditioners and heat‑pumps in eligible regions. The program focuses on reducing electricity consumption: participants receive a thorough inspection and cleaning that catches problems early, avoids costly repairs and improves efficiency. The tune‑up covers condenser and evaporator coil cleaning, blower adjustment and replacement of filters—helping your system run more efficiently.

In addition to provincial programs, federal incentives are available for major upgrades. NRCan’s Greener Homes initiative and the Home Efficiency Rebate Plus (HER+) program offer rebates for high‑efficiency heat‑pumps and central air‑conditioners. These rebates can offset a significant portion of the installation cost, making the switch to a modern system more affordable.

Best practices for homeowners

  • Schedule annual tune‑ups. An air‑conditioner tune‑up identifies minor issues before they become major breakdowns and keeps the system running efficiently.

  • Change filters and clean coils. Dirty filters and coils restrict airflow and lower efficiency. Replace or clean filters regularly and keep coils and ductwork free of dust.

  • Seal and insulate. Caulking and weatherstripping around windows, doors and attic hatches can reduce cooling loads by up to 20%. Adequate attic insulation also slows heat transfer.

  • Use smart thermostats and fans. Smart thermostats adjust temperatures automatically when you’re away, while ENERGY STAR certified ceiling fans help maintain comfort at higher thermostat settings.

  • Shade and ventilation. Close blinds during the day, use awnings, and plant trees to reduce solar heat gain. Use exhaust fans when cooking or showering to reduce indoor humidity.

How professional air conditioning services add value

Working with a certified HVAC contractor ensures that your system complies with the Ontario Electrical Safety Code and manufacturer specifications. Our licensed technicians conduct detailed load calculations, install ductwork for optimal airflow, and integrate smart controls to improve performance. We also handle permit applications and rebate coordination for you.

When paired with energy‑efficiency programs, these services provide immediate and long‑term returns. A properly sized, ENERGY STAR certified system reduces monthly bills, and installation costs may be partially offset through rebates. For property managers and investors, high‑efficiency HVAC upgrades also boost asset value and appeal to environmentally conscious tenants.

Final thoughts

Air‑conditioning is more than a luxury in Chatham‑Kent—it’s a necessity. By prioritizing preventative maintenance, upgrading aging equipment and leveraging government programs, homeowners and businesses can stay cool while controlling costs. Whether you need a routine tune‑up, an emergency repair or a full system replacement, partnering with a professional HVAC contractor like Postma ensures the job is done right.

Replacing your water heater at the right time can help you avoid costly repairs and wasted energy. Whether you’re upgrading for efficiency or dealing with an emergency, now’s the time to act. Get in touch with a trusted HVAC company in Chatham-Kent for a quote and expert advice.


What to Consider Before You Replace

Water heaters typically last between 8 and 12 years, and once they reach that age, especially if they’re showing signs of wear, it’s often more practical to replace them rather than invest in repeated repairs. While traditional tank models are more affordable upfront, tankless systems offer longer lifespans and greater energy efficiency, making them a smart investment for many homeowners. The choice often comes down to your household size and hot water needs; tankless units are great for smaller homes or those looking to reduce energy costs, while tank systems tend to be better suited for larger families with higher usage. No matter which option you choose, professional installation is key—it ensures your system is safely connected, up to code, and operating at peak performance. Some high-efficiency or ENERGY STAR® certified models may even qualify for rebates under broader retrofit programs, so it’s always worth checking with your local HVAC company.

Postma HVAC technician removing an old air conditioning unit from a residential home during an AC replacement service in Chatham-Kent.

Top Signs You Need AC Replacement

Is your home not cooling the way it used to? It might be time for an AC replacement. Many homeowners in Chatham-Kent, Sarnia, Windsor, and St. Thomas delay replacing their AC until it breaks down completely—but waiting too long can cost you more in repairs and energy bills.

In this post, we’ll walk through the most common signs that tell you it’s time to replace your AC, the benefits of upgrading to a new air conditioner, and what to expect from the process. If you’re unsure where to start, Postma is here to help with honest advice and expert service.

Still not sure if your system needs a repair or full replacement?
Read our full guide on AC repairs in Chatham-Kent to compare the signs and make the right call for your home.


Your AC Is Over 10–15 Years Old

Customer review highlighting professional air conditioner installation by Postma Heating & Cooling
Customer review highlighting professional air conditioner installation by Postma Heating & Cooling

Modern air conditioners are built to last—but not forever. If your unit is over 10 years old, it’s likely using outdated refrigerants and consuming more energy than necessary. Older systems are also more prone to breakdowns and typically lack the efficiency ratings of today’s models.

According to Natural Resources Canada, upgrading to a high-efficiency air conditioner can help reduce your energy bills and environmental impact.

How Long Do Air Conditioners Last in Southwestern Ontario?

With our mix of hot summers and humid conditions, most units in our service area last around 12–15 years if properly maintained.


Repairs Are Becoming Frequent and Expensive

If you’re calling for AC repairs more than once a season, your system may be on its last legs. Frequent breakdowns are a sign that components are wearing out and that you might save more in the long run by investing in a replacement.

AC Repair vs. Replacement—Which Saves More?

If the repair costs are over 50% of what a new air conditioner would cost, replacement is usually the better option.

How much does a new air conditioner cost in Ontario?

On average, expect to pay between $3,500 and $7,500, depending on the size of your home and system features.

Can I finance my air conditioner replacement?

 

Yes—Postma offers flexible financing options so you don’t have to sweat a big upfront cost.

Do I need to replace my furnace at the same time?

It depends on your setup. If your furnace is old or incompatible with a new high-efficiency AC, replacing both can improve long-term efficiency.


Energy Bills Keep Climbing

A steady rise in your electricity bill—even though your usage hasn’t changed—can be a clear indicator of an inefficient AC. Today’s energy-efficient air conditioners use far less power while cooling more effectively.

What Makes New AC Units More Efficient?

High SEER ratings, smart thermostats, and inverter technology help reduce energy consumption and improve performance.


Inconsistent Temperatures and Poor Airflow

Are some rooms too hot while others are too cold? Poor airflow or uneven temperatures can indicate duct problems—or a failing AC system. Newer systems are designed to distribute air more evenly across your home.


Your AC Uses R-22 Refrigerant (Freon)

If your system still uses R-22, it’s time to upgrade. R-22 has been phased out in Canada, meaning repairs requiring this refrigerant are not only costly—but nearly impossible.

This phase-out is part of Ontario’s Regulation 189/94 under the Environmental Protection Act, which outlines strict guidelines for handling and servicing ozone-depleting substances like R-22.

What Refrigerant Replaces R-22?

Most new air conditioners use R-410A or newer alternatives that are more efficient and eco-conscious.


Strange Noises, Smells, or Leaks

Unusual noises (like grinding or squealing), unpleasant smells, or moisture around your system are all red flags. These may signal internal damage, mould growth, or refrigerant leaks—all of which are serious concerns that may warrant replacement.

Is It Worth Repairing or Time to Replace?

Sometimes, repairs can keep an aging unit running through the summer. Other times, it’s a short-term solution to a bigger problem. Carrier’s guide to how long air conditioners last explains that most systems have a lifespan of 10–15 years. If your unit is older and frequently breaking down, a new, energy-efficient model might be the smarter investment.

ENERGY STAR’s replacement guidelines recommend considering a replacement if your system is over 10 years old, needs constant repairs, or struggles to cool evenly. Not sure which way to go? We’ll help you weigh your options without pressure.
