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.
Imagine, it's 5 minutes after the midnight countdown New Year's eve and the furnace quits. We called TwinTech fully expecting to leave a message and actually spoke with Greg, one of the owners! We had an immediate repair early the next morning & a new furnace within the week. We have entrusted TwinTech with all our home HVAC service needs for over 6 years. That's why this week with an opportunity to purchase a new BBQ, we called them 1st to see about a gas line install. It's chicken on the grill tonight! They are efficient, reliable, honest, hard working, and -- attentive is an understatement.
Wonderful customer service, starting from the job quote (Dave), to the clean install, to the follow-up. Twintech is a small company which installed my Napoleon furnace, A/C, John Wood tank, and ran the line for my gas dryer. The installation was completed as promised in one day. The work area was kept very clean, and they even took care of my old rental tank. The professionalism and wonderful customer service is second to none. They completed all of my rebate paperwork, and now I'm getting $2000 back! You will not be disappointed if you hire this company for your project.
I was referred to Twintech by a neighbour and was not disappointed. Not only was the customer service excellent their workmanship was second to none. Greg and Grant work extremely clean covering the pathway to the furnace room, labeling the essential parts, left the area spotless and were efficient. They cleaned up the mess left by the previous installers (wiring, improperly installed AC coil, and gaps in venting etc). They also ran through the operation of the new furnace and gave me some maintenance tips. Greg and Grant are professional and all around good guys. I will definitely recommend their service to anyone without hesitation.
Very satisfied with service from Twintech , beginning with all the information provided by Dave , which helped make the decision much easier . Installation was very smooth & done on time as promised & cleanup was well done . Would definitely recommend this company & use them again for any future needs . Well done.
Twintech Heating & Cooling Inc. came in and replaced my 39 year old furnace with a beautiful Napoleon variable high efficiency furnace! Their work was efficient and professional and they were a pleasure to deal with, from sales to installation! I would highly recommend them.
After receiving numerous quotes to replace my old furnace and AC unit (which was 20 years old) I went with Twintech. Dave, in sales, answered questions professionally and promptly and worked diligently in order to secure my business. Installation was scheduled the week after and Greg and Peter showed up, as scheduled, and did a fine job installing both units. The site was left tidy and neat. I would highly recommend Twintech for your furnace and AC work.
I chose TwinTech because they installed my new furnace a few years ago and did a great job. When they installed my new A/C, they replaced all parts -- the copper pipes, the housing on top of the furnace and the wiring. (Apparently, the wiring for my old A/C was insufficient.) Their pricing was competitive. The sales representative came to see me within a few hours of my call. My new A/C was installed a few days later and I couldn't be happier with Twintech's professionalism and work. I would recommend TwinTech to any homeowner.
Had a great experience with this company. Great price and great customer service. You wont be disappointed with twintech. Discussed the job with Greg while he was installing who was extremely informative and obviously enjoys the work he does.
I needed my AC unit relocated due to upcoming landscape work. I reached out to the Twintech team through Homestars. Dave connected with me immediately to discuss the project and various options. We decided the best option was to mount the unit on the wall. Greg was in touch with me the same day as well and we scheduled the work for later that same week. This was a small job so I did not think I would get immediate attention. The Twintech team exceeded my expectations in every respect. They were very knowledgeable and friendly. The team arrived exactly on time on the scheduled day and worked efficiently to get the job done quickly. I would definitely use Twintech again for any Heating and AC projects.
I have used Greg Dainty for over 15 years in 3 different homes, for heating, cooling, pool heaters, appliances and bbq lines. Greg has always been so professional, friendly and the workmanship nothing short of fantastic. Greg has always discussed my options and fixing versus replacing, giving his honest opinion and what works best for me cost effective wise and long term. I have valued his opinion so much and have not trusted my gas needs with anyone since using him. I have also referred him to many of my friends and family and have always been so thankful with how well and quickly he looks after us all. I hold Greg in the highest regard and would recommend him to anyone with complete confidence!

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
So am cleaning my window AC. Was wondering is there a way to open up the front panel fully My guide only shows how to pull out the filter and the part where it is. Cause it definitely needs cleaning further behind. I checked from the outsid
