GENERAL
Working With Excel
Service areas, response times, rebates and what to expect when you call us.
We aim to respond quickly, especially for no-heat and no-cool emergencies.
We serve homeowners across Halton, Hamilton, and Mississauga. That includes Oakville, Burlington, Milton, and Halton Hills in Halton, and Stoney Creek and Ancaster in Hamilton, plus surrounding communities.
Many Ontario homeowners qualify for rebates through the Home Renovation Savings Program, with interest-free financing available through ongoing rebate programs. Eligibility depends on your home and upgrade. We’ll help you check.
It depends on the system’s age, the cost of the repair, and its efficiency. As a rule, we repair what makes sense to repair and only recommend replacement when it’s genuinely the better long-term value. We’ll walk you through both options honestly.
With proper maintenance, most furnaces last around 15 to 20 years and central air conditioners about 12 to 15. Regular servicing helps you reach the upper end of that range and avoid early breakdowns.
We install, service, and maintain heating, cooling, and hot water systems (heat pumps, furnaces, air conditioners, and water heaters) for homes across the region, handled by one team from start to finish.
FURNACES
Furnace Questions
Repair, installation, maintenance and choosing the right furnace for your home.
Furnace Repair
Many common repairs are completed in a single visit, often within an hour or two, because our vans come stocked with the most-needed parts. More complex fixes may take longer, and we’ll let you know upfront.
Yes. Our technicians are trained and equipped to repair every major furnace brand, so you only need one call no matter who made your system or where it was installed.
If your furnace is under about 12 years old and the repair is affordable, fixing it usually makes sense. For older units with a costly repair, replacement may be the smarter long-term value. We’ll give you both options honestly.
Our diagnostic visit covers a technician inspecting your furnace and identifying the problem. We’ll confirm the exact fee when you book, and explain how it applies if you go ahead with the repair.
After-hours and emergency calls may carry an additional charge for the priority response involved. We’ll always tell you the cost upfront before any work begins, so there are no surprises.
We prioritize no-heat emergencies and reach most homes the same day. Response times vary with demand and location, and we’ll always give you a realistic window when you call.
Furnace Installation
In most cases we can schedule your installation with 1-2 days of approval, and sooner in a heating emergency. We’ll always work to get your home warm as quickly as possible.
Cost depends on the furnace model, your home, and the complexity of the install. We provide a clear, upfront quote after assessing your home, so you know the full price before committing.
Furnace size isn’t a guess. We assess your home’s square footage, layout, insulation, and heating needs to size the system properly, so it heats evenly without wasting energy or wearing out early.
Yes. We remove your old furnace and dispose of it responsibly as part of the installation, leaving your space clean and clear once the new system is up and running.
Most standard furnace replacements are completed in a single day, often within four to eight hours. Timing can vary with the complexity of the job, but we’ll give you a clear estimate before we start.
Furnace Maintenance
If we find an issue, we explain what we found, why it matters, and what your options are. Some items may be minor adjustments, while others may require repair or replacement. Our goal is to help you make a clear, informed decision.
Most furnace filters should be checked monthly and replaced every one to three months, depending on the filter type, pets, dust, allergies, and system usage. A clean filter helps protect airflow, efficiency, and the overall health of your furnace.
Yes. A furnace can appear to be working while still developing issues with airflow, ignition, burners, venting, or safety controls. Regular maintenance helps extends your equipment’s life, it can identify problems early, before they affect comfort, efficiency, or reliability.
Most furnace maintenance visits take about 30 to 60 minutes, depending on the system’s age, condition, and accessibility. During the visit, the technician inspects, cleans, tests, and checks key components to confirm the furnace is operating properly.
The best time to book furnace maintenance is late summer or early fall, before your furnace is working every day. Booking early helps avoid the seasonal rush and gives you time to address any issues before colder weather arrives.
Your furnace should be maintained once a year, ideally before the heating season begins. Annual service helps keep the system running safely and efficiently, while giving technicians a chance to catch small issues before they turn into costly winter breakdowns.
Furnace Buying Guide
Cost depends on the furnace type, efficiency, your home, and the complexity of the install. We give you a clear, upfront quote after assessing your home, so you know the full price before deciding.
Many Ontario homeowners qualify for rebates and interest-free financing through provincial and federal programs. Furnace-specific rebates tend to be modest, while larger incentives apply to heat pumps. We’ll help you check what fits.
Often, yes. A high-efficiency furnace costs more upfront but uses less fuel every winter, so it pays some of that back in lower bills. How quickly depends on your usage and energy prices. We’ll help you weigh it honestly.
Furnace size is based on your home’s square footage, layout, insulation, windows, and climate, not a rule of thumb. We calculate the right capacity for your home so it heats evenly without short-cycling or running constantly.
AFUE (Annual Fuel Utilization Efficiency) is the percentage of fuel a furnace turns into usable heat. A 96% AFUE furnace converts 96% of its fuel to warmth and wastes only 4%. The higher the AFUE, the lower your energy bills.
With regular maintenance, furnaces last around 12 to 16 years. Efficiency and reliability tend to decline in the final years, so if yours is in that range and needing repairs, it may be worth planning a replacement.
HEAT PUMPS
Heat Pump Questions
Cold-climate performance, rebates, sizing and keeping your heat pump running efficiently.
Heat Pump Repair
After-hours and emergency calls may carry an additional charge for the priority response involved. We’ll always tell you the cost upfront before any work begins, so there are no surprises.
Yes. Our technicians are trained and equipped to repair every major heat pump brand, so you only need one call no matter who made your system or where it was installed.
Weak heating can come from low refrigerant, a stuck reversing valve, a defrost problem, or a dirty coil, among other causes. Because heat pumps are complex, it’s best to have a technician diagnose it properly rather than guess. We’ll find the real cause.
If your heat pump is under about 8 to 10 years old and the repair is reasonable, fixing it usually makes sense. For older systems facing a major repair like a compressor, replacement may be the smarter long-term value. We’ll give you both options honestly.
Some frost is normal in winter, and a heat pump runs defrost cycles to clear it. Heavy or persistent ice, though, points to a problem, such as a stuck defrost cycle, low refrigerant, or airflow issues, and should be checked before it causes damage.
We prioritize breakdowns that leave you without heating or cooling and reach most homes the same day. Response times vary with demand and location, and we’ll always give you a realistic window when you call.
Heat Pump Installation
In most cases we can schedule your installation within a few days of approval, and we’ll always work to accommodate your timing, especially heading into the heating or cooling season.
Yes. Rebate applications can be involved, so we guide you through the process and handle the paperwork, making it as easy as possible to claim the incentives you’re entitled to.
Heat pumps qualify for the largest home-comfort rebates in Ontario. The exact amount depends on your home and equipment, and we’ll confirm everything you qualify for.
Not always. A properly sized cold-climate heat pump can replace your furnace entirely, or we can set up a hybrid system that keeps your furnace as backup for extreme cold. We’ll recommend the best approach for your home and budget.
Heat pump sizing isn’t a guess, and it matters even more in our climate. We perform proper load calculations based on your home’s size, layout, insulation, and windows, so the system keeps up on the coldest days without wasting energy.
Most heat pump installations are completed in one to two days, depending on whether it’s a straightforward replacement or involves ductwork, electrical upgrades, or a ductless setup. We’ll give you a clear timeline before we start.
Heat Pump Maintenance
Most heat pump maintenance visits take about 45 to 75 minutes, depending on the system’s age, condition, and accessibility. During the visit, the technician inspects, cleans, tests, and checks key components so the system is ready for the season.
Yes. A heat pump can appear to be working while still developing issues with refrigerant, defrost, coils, or electrical components. Regular maintenance extends equipment life and identifies problems early, before they affect comfort, efficiency, or reliability.
Most filters should be checked monthly and replaced every one to three months, depending on the filter type, pets, dust, allergies, and system usage. A clean filter protects airflow, efficiency, and the overall health of the system.
If we find an issue, we explain what we found, why it matters, and what your options are. Some items may be minor adjustments, while others may require repair or replacement. Our goal is a clear, informed decision.
Your heat pump should be maintained twice a year: once before the heating season and once before the cooling season. Because it runs year-round, regular service keeps it efficient and gives technicians a chance to catch small issues before they turn into breakdowns.
The best times are early fall, before heating season, and early spring, before cooling season. Booking ahead of the rush gives you time to address any issues before peak weather arrives.
Heat Pump Buying Guide
Cost depends on the type, size, efficiency, and your home. Rebates can offset a portion. We provide a clear, upfront quote after assessing your home, so you know the full price and the after-rebate cost before deciding.
With regular maintenance, most heat pumps last around 15 years. Because they run year-round for both heating and cooling, consistent servicing is especially important to reach the upper end of that range.
In many cases, yes, thanks to their efficiency, though it depends on your home, electricity and gas rates, and how cold it gets. We’ll give you an honest picture of the likely running costs for your specific situation rather than a blanket promise.
Heat pumps qualify for the largest home-comfort rebates in Ontario, which can offset a significant share of the cost. The exact amount depends on your home and equipment, so we’ll confirm what you qualify for.
Often, yes. A properly sized cold-climate heat pump can be your primary heating and cooling for the whole year. Some homeowners keep their furnace as backup in a ‘hybrid’ setup for extreme cold. We’ll advise which approach fits your home and budget.
Yes. Today’s cold-climate heat pumps are designed to deliver efficient heat well below freezing, far better than older models. Proper sizing matters, and some homes pair a heat pump with a backup heat source for the very coldest days. We’ll advise what suits your home.
AIR CONDITIONERS
Air Conditioner Questions
Cooling repairs, new system installs, seasonal tune-ups and picking the right unit.
Air Conditioner Repair
We prioritize no-cooling calls during heat waves and reach most homes the same day. Response times vary with demand and location, and we’ll always give you a realistic window when you call.
After-hours and emergency calls may carry an additional charge for the priority response involved. We’ll always tell you the cost upfront before any work begins, so there are no surprises.
Yes, our diagnostic visit covers a technician inspecting your AC and identifying the problem. We’ll confirm the exact fee when you book and explain how it applies if you proceed with the repair.
If your AC is under about 10 to 12 years old and the repair is affordable, fixing it usually makes sense. For older units facing a major repair like a compressor, replacement may be the smarter long-term value. We’ll give you both options honestly.
Yes. Our technicians are trained and equipped to repair every major air conditioner brand, so you only need one call no matter who made your system or where it was installed.
An AC that runs without cooling often points to a refrigerant leak, a frozen coil, a dirty condenser, or a failing compressor. These need a proper diagnosis, so it’s best to book a technician rather than keep running the system and risk further damage.
Air Conditioner Installation
Most standard AC installations are completed in a single day, often within four to eight hours. Timing can vary with the complexity of the job, such as new ductwork or electrical work, and we’ll give you a clear estimate before we start.
AC size isn’t a guess. We assess your home’s square footage, layout, insulation, and windows to size the system properly, so it cools evenly and efficiently without short-cycling or running constantly.
Yes. We remove your old air conditioner and dispose of it responsibly as part of the installation, leaving your space clean and clear once the new system is up and running.
Many homeowners qualify for provincial rebates and interest-free financing. The largest rebates apply to heat pumps rather than cooling-only ACs, so we’ll confirm what fits your situation and goals.
Cost depends on the system, your home, and the complexity of the install. We provide a clear, upfront quote after assessing your home, so you know the full price before committing.
In most cases we can schedule your installation within a few days of approval, and sooner during a summer heat wave when you need cooling fast. We’ll always work to get your home comfortable as quickly as possible.
Air Conditioner Maintenance
Most AC maintenance visits take about 30 to 60 minutes, depending on the system’s age, condition, and accessibility. During the visit, the technician inspects, cleans, tests, and checks key components to confirm the air conditioner is operating properly.
Yes. An air conditioner can appear to be working while still developing issues with coils, refrigerant, airflow, or electrical components. Regular maintenance extends equipment life and identifies problems early, before they affect comfort, efficiency, or reliability.
Most filters should be checked monthly and replaced every one to three months, depending on the filter type, pets, dust, allergies, and system usage. A clean filter protects airflow, efficiency, and the overall health of the system.
If we find an issue, we explain what we found, why it matters, and what your options are. Some items may be minor adjustments, while others may require repair or replacement. Our goal is a clear, informed decision.
Your air conditioner should be maintained once a year, ideally in spring before the cooling season begins. Annual service keeps the system running efficiently and gives technicians a chance to catch small issues before they turn into mid-summer breakdowns.
The best time to book AC maintenance is early spring, before your system is working every day. Booking early avoids the seasonal rush and gives you time to address any issues before the first heat wave.
Air Conditioner Buying Guide
Cost depends on the system type, efficiency, your home, and the complexity of the install. We give you a clear, upfront quote after assessing your home, so you know the full price before deciding.
Rebate programs mostly reward heat pumps, which both heat and cool, rather than cooling-only air conditioners. If you’re open to a heat pump, you may qualify for significant incentives. We’ll confirm what applies.
Central air is ideal if you already have ductwork and want whole-home cooling. Ductless mini-splits are great for homes without ducts, additions, or cooling specific rooms. We’ll advise which fits your home and budget best.
SEER2, the current efficiency standard, measures how efficiently an AC cools over a season. A higher SEER2 means less energy used for the same cooling, which lowers your summer bills. Higher-SEER2 units cost more upfront but save over time.
AC size is based on your home’s square footage, layout, insulation, and windows, not a rule of thumb. We calculate the right cooling capacity for your home so it cools evenly and efficiently without short-cycling or running non-stop.
With regular maintenance, most central air conditioners last around 12 to 15 years. If yours is in that range and needing frequent repairs, it’s often worth planning a replacement before it fails in peak summer.
WATER HEATERS
Water Heater Questions
Tank and tankless repair, replacement and how to choose your next water heater.
Water Heater Repair
Running out quickly can mean sediment is taking up space in the tank, a heating element or thermostat is failing, or your unit is simply undersized for your household’s demand. We’ll diagnose the cause and recommend the right fix.
Yes. Our technicians are experienced with both gas and electric water heaters, as well as tankless units, so we can diagnose and repair whatever type you have safely and correctly.
Rumbling or popping is almost always sediment that has built up and hardened at the bottom of the tank. It makes the unit work harder and less efficiently. A flush often quiets it and restores performance, and we can check whether additional service is required.
If your unit is under 10 years old and the repair is affordable, fixing it usually makes sense. For older units, a leaking tank, or a repair approaching half the cost of a new one, replacement is often the smarter long-term value. We’ll advise honestly.
A small leak from a valve or fitting is often repairable, but a leaking tank can cause water damage and usually means the unit needs replacing. Either way, it’s worth acting quickly, so turn off the water supply and call us to assess it.
We prioritize no-hot-water and leaking-unit calls and aim to reach you as quickly as possible, often the same day. Response times vary with demand and location, and we’ll always give you a realistic window when you call.
Tankless Water Heater Repair
Fluctuating temperatures, sometimes called the ‘cold water sandwich’, can result from scale buildup, a flow or sensor issue, or an undersized unit for your demand. We’ll diagnose why it’s happening and recommend the right fix.
Yes. Our technicians are trained and equipped to repair every major tankless brand, so you only need one call no matter who made your system or where it was installed.
Usually, yes. Tankless units are a significant investment and can last well over 15 years, so repairs are often worthwhile, especially for a newer unit. For an older unit with a failed heat exchanger, replacement may make more sense. We’ll advise honestly.
In areas with harder water, most tankless units benefit from descaling roughly once a year to clear mineral buildup that hurts efficiency and performance. Regular descaling is one of the best ways to keep your unit running well and lasting longer.
A tankless unit can stop heating due to scale buildup, a flow sensor problem, an ignition fault, or a gas or venting issue. Because these systems are technical, it’s best to have a specialist diagnose it properly rather than guess. We’ll find the cause.
Error codes point to a specific fault, from ignition or flow issues to scale buildup or venting problems. The meaning varies by brand and code. Our technicians can read the code, diagnose the underlying issue, and explain exactly what’s needed.
Water Heater Installation
In most cases we can schedule your installation within a few days of approval, and sooner if you’re left without hot water. We’ll always work to get your hot water back as quickly as possible.
Yes. We remove your old water heater and dispose of it responsibly as part of the installation, leaving your space clean and clear once your new unit is running.
Cost depends on the type, the unit, and the complexity of the install, especially if you’re switching types. We provide a clear, upfront quote after assessing your home, so you know the full price before committing.
Efficient models, especially hybrid heat pump water heaters, may qualify for rebates or financing programs. We’ll help you check what applies.
Yes. We can convert a tank system to tankless, though it may involve venting and gas-line changes to suit the new unit. We’ll assess your setup, explain what’s involved, and give you a clear quote before any work begins.
A straightforward tank replacement is often done in a few hours. Switching types, such as tank to tankless, can take longer if venting, gas, or electrical changes are needed. We’ll give you a clear timeline before we start.
Water Heater Buying Guide
Cost depends on the type, fuel, size, and installation complexity. A basic tank is the most affordable; tankless and hybrid units cost more upfront but can save over time. We provide a clear, upfront quote after assessing your home.
Efficient models, particularly heat pump water heaters, may qualify for provincial or federal rebates. Standard tank and tankless units typically do not qualify for rebates. We’ll help you check what applies to the unit you’re considering.
For many homes, yes. Heat pump water heaters are the most efficient type and can significantly cut water-heating costs over time. They cost more upfront and need adequate space, but rebates and long-term savings often make them worthwhile.
Sizing depends on your household size, number of bathrooms, and peak hot-water demand. A tank is sized by capacity in litres or gallons, a tankless by flow rate. We’ll calculate the right size so you never run short or overpay.
A conventional tank typically lasts about 10 to 12 years, while tankless units can last 15 to 20 or more with proper care. Regular maintenance, like flushing and descaling, helps any water heater reach the upper end of its lifespan.
It depends on your priorities. Tankless offers endless hot water, space savings, and long-term efficiency at a higher upfront cost. A tank is cheaper to buy and simpler to install. We’ll help you weigh which fits your home, usage, and budget.
