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.

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.

We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.
