As warm weather approaches, many of us crank up our air conditioning systems to stay cool and comfortable. At Presidential Ventilation Systems Ltd., we understand that running your HVAC system smoothly is essential during hot months. Before giving us a call, there are a few things you can check yourself to ensure your system is working efficiently.
With over 2 decades of experience serving residential and commercial customers, we've seen it all. Here are some tips from our expert technicians to help you troubleshoot common HVAC issues before they become more significant problems. Remember, if you need assistance, we're always here to help. You can get in touch with us at any time for professional heat pump services or for advice.
Maintaining your HVAC system during the warm months is essential for keeping your space comfortable and your energy bills in check. These simple service tips can help you troubleshoot common issues before they escalate:
One of the most common issues that can affect your HVAC system's performance is a dirty air filter. When filters get clogged with dirt and dust, it reduces airflow, making your system work harder to maintain the desired temperature. This can result in higher energy bills and potential damage to the system over time.
Tip: Inspect your filter regularly, especially during heavy use periods like summer. If it's dirty, clean or replace it. For ducted systems, we recommend replacing the filter every 1-3 months depending on usage. By ensuring your filter is clean, you improve airflow and extend the longevity of your HVAC system. We provide high-quality filters and can help you find the right one for your system.
Checking the condensate line is essential for homes with ducted heat pump systems. Over time, the clear p-trap in the line can become clogged with debris, resulting in water leaks and potential damage to your home.
Tip: Make sure the p-trap is free of obstructions. Use the brush to clear any debris. If you're unsure about how to do this, our professionals can walk you through the process or take care of it during your next maintenance visit. Keeping your condensate line clear ensures your heat pump system runs efficiently without causing water damage.
If you have a ductless system, it's essential to ensure water drains properly from the exterior drain tubing. If you notice that no water is coming out, there could be an obstruction in the drain line or drain pan. This can cause an overflow of water, which may drip from the front or bottom of the unit.
Tip: If you suspect an obstruction, it's vital to act quickly to avoid water damage. You can try clearing the obstruction yourself, but if the issue persists, call us. We're experts in servicing ductless systems and can resolve the problem efficiently.
Sometimes, the issue with your HVAC system may be as simple as incorrect thermostat settings. Before assuming a bigger problem, check your thermostat to confirm it is correctly set for cooling or heating. If necessary, switch the mode to "off" and then back to cooling or heating. Wait for about five minutes, as some thermostats or outdoor units have a built-in delay that prevents the compressor from starting immediately.
Tip: Programmable thermostats are great for energy savings but can also be tricky to troubleshoot. If you're unsure about your settings or suspect a thermostat malfunction, our technicians are here to help. We can assist with troubleshooting or recommend an upgrade if your thermostat is outdated.
A tripped circuit breaker or a blown fuse could be the reason your HVAC system isn't working. However, it's important to approach this issue with caution. A tripped breaker usually indicates a more significant electrical problem, and resetting it without professional advice can be dangerous.
Tip: If you notice a tripped breaker, do not reset it on your own. Instead, give us a call. We'll assess the situation and determine whether it's a minor issue or if there's a more significant problem that needs to be addressed. We pride ourselves on offering expert diagnostics and solutions to keep your home safe.
Your outdoor unit requires proper airflow to operate efficiently. Obstructions like leaves, dirt, or debris can significantly restrict airflow, putting extra strain on your system. This forces your air conditioning or heating system to work harder to maintain the desired temperature, resulting in higher energy bills. Over time, restricted airflow can lead to overheating and potential damage to the unit.
Tip: Check the area around your outdoor unit and remove any debris obstructing airflow. Ensure the unit is not covered on the sides or top.
Sometimes, the problem with your HVAC system may be as simple as a blocked air supply or return grills. Furniture, rugs, or curtains can inadvertently block the grills, preventing proper airflow throughout your home.
Tip: Walk around your home and check that all supply and return vents are open and unobstructed. Keeping these areas clear helps your system maintain a consistent temperature and prevents unnecessary strain on your HVAC system.
Your HVAC system should operate relatively quietly, with only the sound of air moving through the ducts or the outdoor unit's fan running. If you find unusual sounds such as grinding, banging, or squealing, this could indicate a mechanical issue that needs attention.
Tip: Don't ignore strange sounds coming from your system. Call us immediately if you hear anything unusual. Catching a problem early can prevent a more costly repair down the line.
Many modern HVAC systems will display error codes when something goes wrong. For ductless systems, continuous blinking usually indicates an error. For ducted systems, you may see an error code on the thermostat or furnace.
Tip: If you notice an error code, refer to your system's manual to identify the problem. If you're unsure, our team can quickly diagnose and resolve the issue.
After performing these checks, if your system still isn't running smoothly, it's time to call the professionals.

Our experts are fully trained and certified, and we're members of the Better Business Bureau with an A+ rating. If you need assistance, don't hesitate to contact us today.

Heat pumps not working in Truro NS can quickly turn a comfortable home into a cold, frustrating situation. Whether you're dealing with cold air from your vents, a unit that won't turn on, or strange noises, you need answers fast. The good news is that many common heat pump problems have simple fixes you can try yourself before calling a professional.
Quick troubleshooting checklist for heat pumps not working:
For comprehensive guidance on heat pump services in the Truro area, visit our main heat pump services page. If you need immediate professional assistance, contact our certified technicians for expert diagnosis and repair.
Truro's cold winters put extra strain on heat pump systems. This guide walks you through the most common issues and shows you what to do about them, saving you time, money, and discomfort.

Before you panic about heat pumps not working in Truro NS, take a moment to perform a few simple checks. Often, the solution is something you can fix yourself in minutes without any special tools. This is your heat pump's "first aid" checklist.

Incorrect thermostat settings cause a surprising number of service calls. Start with the basics: is your thermostat set to "Heat" mode? Ensure the temperature is set higher than the current room temperature. If it's 18°C in your living room and your thermostat is set to 17°C, your heat pump is doing exactly what you told it to do – nothing.
The fan setting also matters. Keep it on "Auto" so the fan only runs when the system is actively heating. If it's set to "On," the fan blows continuously, which can feel like cold air between heating cycles.
Finally, check the digital display. If it's dim or blank, try replacing the batteries. Many hardwired thermostats use backup batteries that can cause issues when they die.
A clogged air filter can make your heat pump struggle, causing it to shut down or blow cold air. Your air filters should be checked monthly, especially during Truro's coldest months. Depending on your household, you may need to clean or replace them every one to three months.
For washable filters, follow the manufacturer's instructions and ensure they are completely dry before reinstalling. For disposable filters, simply slide the old one out and put the new one in, making sure the airflow arrow points in the right direction. Clean filters improve indoor air quality, reduce energy bills, and prevent major breakdowns.
If your heat pump is unresponsive, check if it's receiving electricity. Head to your electrical panel and look for tripped circuit breakers. Heat pumps typically have two breakers (one for the indoor unit, one for the outdoor). If a breaker is tripped, flip it fully to "off" before switching it back to "on."
Also, check the outdoor disconnect switch, a box usually mounted on the wall near your outdoor unit. Ensure it's in the "on" position.
After a power outage in Nova Scotia, a proper reset procedure is crucial. For a standard heat pump, once power returns, switch your thermostat to "Emergency Heat" and wait at least six hours before returning to normal heat mode. This allows the compressor oil to warm up, preventing damage.
For mini-split systems, turn the power off at the breaker, wait 30 seconds, then turn it back on. Wait about 30 minutes for the system to recalibrate before turning it on via the remote. Patience after an outage can prevent a simple power blip from becoming a major repair for heat pumps not working in Truro NS.
Even with diligent care, heat pumps can run into trouble, especially given Truro's challenging winter climate. Heavy snow and ice can push your system to its limits, leading to problems with your heat pumps not working in Truro NS when you need them most.

Feeling cold air from your vents doesn't always mean disaster. The most common reason is the heat pump's defrost cycle. When temperatures drop below 5°C, frost naturally forms on the outdoor unit. The system temporarily reverses itself for 5 to 15 minutes to melt this frost, during which it may blow cooler air. You might see steam rising from the outdoor unit, which is normal.
If the cold air persists, you could have low refrigerant levels due to a leak. Refrigerant is the substance that transfers heat, and low levels prevent your system from heating effectively. This requires a professional to fix. Also, double-check your thermostat settings to ensure they are correct.
A light dusting of frost is normal, but a unit encased in thick ice is a problem. This can be caused by several issues:
If you see heavy ice, gently clear away snow and debris, but never try to chip the ice off the delicate coils. If the ice doesn't clear on its own or keeps returning, it's time to call a professional.
Learning to distinguish normal from problematic sounds can save you from worry and expensive repairs. Normal sounds include whooshing as refrigerant moves, clicking from relays, and soft ticking as metal expands and contracts.
Problem noises require attention:
If a sound seems wrong, it's worth getting it checked out. Catching problems early is always better than dealing with a complete system breakdown.
While DIY troubleshooting can resolve minor issues, some problems with heat pumps not working in Truro NS require a certified HVAC professional. Attempting complex repairs yourself can be dangerous, void your warranty, and potentially make the problem worse.

Here's when to pick up the phone:
If you suspect any of these issues, our licensed technicians are ready to provide expert diagnosis and repair for your heat pump in Truro.
Sometimes, the reason your heat pumps not working in Truro NS effectively is due to improper sizing or installation. An undersized unit will run constantly without ever reaching the desired temperature, leading to high energy bills and premature wear. Conversely, an oversized unit will "short cycle" – turning on and off frequently. This causes uneven temperatures, poor dehumidification, and unnecessary stress on components.
Even a perfectly sized unit will underperform if not installed correctly. Issues like an improper refrigerant charge or poor electrical connections can hinder efficiency and reliability. At Presidential Ventilation Systems Ltd., we conduct a thorough assessment to ensure your heat pump is sized and installed correctly for your home and the Truro climate, guaranteeing optimal performance and longevity.
Regular maintenance is the best way to prevent heat pumps not working in Truro NS during a cold snap. Just like a car needs oil changes, your heat pump needs professional tune-ups to handle the demands of Nova Scotia's climate.
Annual maintenance with our licensed technicians offers several key benefits:
During a professional tune-up, we perform a comprehensive check, including cleaning coils, verifying refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing overall system operation. For tips on what you can do between visits, you can reference general regular maintenance advice.
As a leading Daikin Comfort Pro Dealer, we know what it takes to keep a heat pump running reliably in our local climate. Scheduling annual maintenance protects your investment and ensures your family's comfort year-round.
Here are answers to common questions about heat pumps not working in Truro NS.
During Truro's coldest months (especially below -10°C), it's normal for a heat pump to run almost continuously. It has to work harder to extract heat from the frigid air. Other common causes include a large thermostat adjustment, a dirty air filter, or a blocked outdoor unit.
However, if your unit runs constantly in milder weather (around 5°C), it could indicate a more serious issue like an undersized system or low refrigerant levels, which requires a professional inspection.
A reset can sometimes fix minor glitches. To do it safely:
For a ductless mini-split after a power outage, turn the breaker back on and wait 30 minutes for it to recalibrate before using the remote. If a reset doesn't solve the problem, call a professional.
Yes, a light layer of frost is completely normal in winter. Your heat pump has a built-in defrost mode that runs periodically (every 30-90 minutes) to melt this frost. During this 5-15 minute cycle, you might see steam rising from the unit, which is normal.
However, a thick, solid block of ice is a sign of a problem. It could mean the defrost cycle is malfunctioning, airflow is blocked, or refrigerant is low. If you see heavy ice that doesn't melt, it's a clear sign your heat pumps not working in Truro NS correctly and needs a professional inspection. Do not try to chip the ice off yourself.
By following this guide, you've learned how to troubleshoot common issues causing heat pumps not working in Truro NS. You know how to check your thermostat, filters, and power supply, and can distinguish normal frost from problematic ice.
However, safety always comes first. If you've tried the DIY fixes and your heat pump is still malfunctioning, or if you notice serious red flags like hissing sounds, burning smells, or loud grinding noises, it's time to call a professional. These issues are often too complex or dangerous for a DIY approach.
