How your Furnace and Air Conditioner work together to keep you Comfortable?
Posted On: April 14, 2019
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.

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Great Team! Furnace broke in the weekend, Bob visited same day and Greg installed new one on Monday. Team was professional, respectful and knowledgeable. Installation went very well, Greg found solutions to challenges, like hiding new conduits in the ceiling. Looks nice and new furnace is working great. Five Stars.

I used Twintech to install a new furnace for my home. Bob was terrific in explaining the sizing options and why the 2 stage furnace was the best option for me. Greg did a great job installing, clean and on time. Finished work looks great but the best part is how it works. The 2 stage heating is so much more comfortable. I run the fan continuously to keep the indoor air clean. Great investment! Would highly recommendTwintech!

Im going to start this by saying Im a very particular customer. My background is in mathematics and mechanical engineering so I have an eye for detail and a respect for technical knowledge.
Greg had already done an AC inspection and replaced a water heater tank and there was no question in my mind who to deal with replacing my rickety old furnace after it got pooched.
Bob dropped in ahead of time and clearly (and knowledgeably) outlined all technical, price and operational options.
Greg showed up on time, on the agreed date and did a fantastic job. (The OLD furnace was a house of horrors and was installed in a keystone cops sort of way- careless.)
The work Greg did was HIGHLY PROFESSIONAL and FAR MORE FUNCTIONAL than what I had.
Im also a musician with many instruments so maintaining predictable humidity/temperature is extremely important to me. Greg recognized this as did Bob. You NEVER feel like youre being brushed off.
In summary, if youre looking for PROFESSIONAL, QUALITY results by an EXPERIENCED, THOUGHTFUL team
(that also happen to be FRIENDLY and ATTENTIVE ) then youve come to the right page!!

I had a problem with the Furnace (Armstrong ultra V) and Greg diagnosed it on the phone. Even told me what the issue was and I was able to fix it. This level of service from a Business that is almost unknown today.
If you require service, reach out to Greg. I will definitely use them in the future!
