How your Furnace and Air Conditioner work together to keep you Comfortable?

Furnaces are used to generate heat and spread it throughout your home.


 A furnace is connected to a duct system that will distribute heated air to the various rooms of your home, which is crucial during the colder months of the year.


The heating process begins when the thermostat senses the temperature in your house dropping a little below its set point.


The thermostat then sends a signal to the furnace to initiate the sequence of operation needed to bring on the heat source.


Heat can be produced by means of energy from multiple sources, such as electric heat, natural gas, propane gas or fuel oil.


Electric furnaces heat up like large toasters, while oil and gas furnaces employ the use of electrically signaled control valves to produce flames.


 Once the furnace heats up for a short time the furnace blower kicks in to circulate heated air throughout the rooms of your home.


When the thermostat is satisfied that the temperature it senses has slightly exceeded its set point it cuts off the signal to your furnace and the heating cycle comes to an end shutting off the burners or electric elements, leaving only the furnace blower fan running for a little longer to push any heat remaining in the duct system.


 During the summer when the temperature in your home rises above the air conditioning set point it sends a signal bringing on both the air conditioner and the furnace blower.


The outdoor AC unit houses a compressor which pumps refrigerant to an evaporator coil located inside near the furnace.


Proper functioning of your central air conditioner depends upon the correct indoor air flow provided by the furnace, and correct air flow through the AC condenser coil in order to keep the compressor running properly.


 To ensure that your furnace is running optimally, regular annual maintenance is recommended in order to minimize the chance that your system will break down during a heat wave in the summer, or during a winter cold spell.


Sometimes it is difficult to diagnose the reasons why your furnace or air conditioner is not working.


The best way to figure out the problem is by first looking over the entire system for any obvious installation related issues.


After all, you can buy the best equipment but if it’s not installed correctly the result can be unreliable or inefficient operation.


Proper setup, known as commissioning, is very important in a complete and thorough installation so that your furnace and air conditioner are operating as they were designed to.


 During the summer months, your furnace fan and electronic controls are used almost as much as they are in the winter.


If the furnace blower motor stops working this can result in the air conditioning coil freezing up which can damage your furnace.


Most of today’s gas furnaces contain electronic controls and do not like to get wet so when a frozen coil above the furnace starts to thaw and drip water onto the electronics the circuit board will usually short out and will need to be replaced.


A skilled technician will properly diagnose any issues with your air conditioning system such as improper air flow, incorrect refrigerant charge or any other common issues that are found on a service call.

by Linda, Toronto on Twintech Heating and Cooling

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

by Sean, Whitby on Twintech Heating and Cooling

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.


Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.


Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!

by Bill, Oshawa on Twintech Heating and Cooling

We are very happy with our new furnace. The service was excellent the guys worked 6 hours straight through and there was no mess at all they took the old furnace box’s etc with them they then explained everything to us they were very helpful and pleasant , when we need a new air conditioner we know who to call!

by Ken, Bomanville on Twintech Heating and Cooling

The crew from sales to installation was very professional and had great attention to detail

by Tracy, Pickering on Twintech Heating and Cooling

We couldn’t have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.


We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.


Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.


Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

by Skapoor, Ajax on Twintech Heating and Cooling

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

by Steve, Oshawa on Twintech Heating and Cooling

We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time


We would highly recommend them to whoever needed a recommendation


We have a very large dog and they were very understanding and respectful of him being around
