Call us for a Furnace Maintenance Service

Poor maintenance can lead to a crack in several ways:

Improper Air Flow

Dirty filters, closed off vents or furniture blocking return vents can all contribute to improper air flow. As a result the lack of air crossing through the heat exchanger causes it to overheat making it more prone to cracking.

Improper Manifold Pressure

Your gas valve controls the flow of gas into your burners. If it’s allowing too much gas it can cause the same overheating condition as restricted air flow. Likewise if it’s allowing too little gas it increases run time and wears out the heat exchanger faster.

Improper Displacement of Condensation

This is most common in devices that have not been run (heat or cool) in a long time; they accumulate condensation in the heat exchanger, eventually rusting out the system.It is imperative that the heat exchanger isn’t cracked in order for it to separate the burner gas from the circulation air. Mixing the two will create carbon monoxide.

The AccuServ Team – Furnace Maintenance Toronto

Our technicians are very knowledgeable about the operation of furnaces and how to properly maintain and repair them. As specialists they go through intensive one on one courses on how to do proper safety checks, readings, measurements and most importantly, ensure the heat exchanger is not cracked. We also ensure they’re equipped with the right tools to do the job. These include:

Camera Scope: a handheld camera with a scope in order to thoroughly inspect the condition of a heat exchanger

Gas Sniffer: A highly sensitive natural gas sensor that ensures there is no gas leak in or near your furnace

Combustion Analyzer: Probably one of the most important tools, it detects if there is any CO present in the room or in the furnace. It can also be used to detect other fatal gases

Low Monthly, High Value

Our highly skilled technicians follow a very detailed list of 21 inspections and cleaning, providing you with the most thorough maintenance in the industry.

Furnace Installation and Replacement Financing

Financing a Replacement Has Never Been Easier!

At AccuServ, we understand that HVAC repairs can be expensive – especially when you’re living with an antiquated, rundown machine. Whether your furnace needs a much needed tune-up, or you simply want to upgrade to a more energy efficient model (but can’t justify large upfront costs of buying one to make the switch), we have the solutions for your budget.

Let us serve as the financial segue to fast and friendly financing options. For a small monthly payment, you can have a one that delivers increased comfort and reliability. Best of all, if you’re replacing an mid-efficient device you can drastically reduce your energy bill; allowing you to relish the warmth during the winter months and save more money!

Why Financing Makes Sense

It’s a pretty simple concept: a low-to-mid efficiency furnace is burning your hard-earned dollars up the chimney. In fact, statistics show that a 30+ year old furnace could waste as much as 40 percent of your energy!¹ Even a furnace dated 15 to 20 years old poses an estimated 20-25 percent of wasted expenditures.

A quick way HVAC specialists estimate a system’s current efficiency level is by utilizing the following rule of thumb:

Take the systems efficiency rate upon installation and deduct 1 percent in efficiency for every year the system has been in operation. This would mean that after 15 years, a furnace originally installed at 80 percent efficiency would be operating at an estimated 65 percent AFUE.

Let’s put a monetary value in the equation. If you spend $1 of gas – but your furnace is only able to use 65 percent of that to heat your home – you’re only getting $0.65 worth of that $1 you put in. In short, you’re wasting $0.35 for every $1 you spend!

Frequently Asked Questions

How often should I have an inspection?

Annual inspections are recommended for most types of furnaces. This is best done before temperatures start to drop, so you can be sure that you’ll be able to enjoy your furnace when you need it. During an inspection, we’ll check for issues that could cause future breakdowns, and recommend replacements for parts that have experienced significant wear.

How can I tell if I need a fix vs. a replacement?

If you don’t have any experience, it can be difficult to tell if you need basic repairs or a full installation. Our team members have a lot of experience with all types of systems, including those that are decades old. We’ll do what we can to put even the oldest ones back in working order, and we can help you make the right decisions.

Is it always serious if I smell gas?

If you smell gas, particularly if you believe the source is your furnace, everyone should immediately leave the home and contact emergency services. Gas scents should always be considered dangerous. Once gas service to the home has been cut off, our repair experts should be able to inspect the furnace or other home appliances to determine if it is the source of the leak.
