Conventional HVAC System FAQs – Burning Questions About Cooling Units

Conventional HVAC System FAQs – Learn the Mechanics of Your AC Unit to Prepare You for the Hot Season

While it’s still cold outside you may want to start thinking about updating or installing a new air conditioning system for when the temperatures start to rise. Two major options you have are to use a conventional HVAC (heating, ventilation, air conditioning, and cooling) system or a heat pump unit. Today we cover several FAQs generally asked about conventional HVAC equipment.

What is a conventional HVAC system?

A conventional HVAC system is a conventional air conditioner. Usually referred to as “central air conditioning”, its chief purpose is to move heat from the inside of your home to the outside during the summer. These units work using a condenser on the outside of your home and an evaporator on the inside to draw hot air from your house, cooling it on the evaporator coils.

How does a conventional HVAC system work?

A compressor compresses refrigerant contained in the AC system, causing the temperature to rise. This heated gas flows through the condensing coil and cools to ambient temperature, outside the home. Then, the gas enters the evaporator coil on the inside of the home where it expands and quickly decreases in temperature, cooling the coil.

This cool air is then distributed through your home using a fan or blower assembly that draws air through the cooled evaporator coil and throughout the ductwork to blow the new, refreshing air throughout each room of your house.

What’s the difference between a conventional system and a heat-pump unit?

Although both systems are technically considered to be a heat pump because they transfer heat from inside the home to the outside to cool interior temperatures, the two units are markedly different. The major difference is in the cycle of heat transfer. A heat pump can reverse its direction and transfer heat from the outside to heat indoor temperatures, whereas a conventional air conditioning system requires a separate furnace unit to produce and distribute warm air.

Which unit is the best for my climate?

People who live in climates where they experience long durations of temperatures below 40 degrees should utilize a conventional HVAC system. You do need an additional furnace or heating unit, but heat pumps lose their heating efficiency in these chronically extreme temperatures because they have to switch to emergency heat mode, which uses more electricity.

However, if the climate you live in is more balmy or moderate, a heat pump is a great idea. You don’t need a separate unit to heat your home in the winter and they tend to be more energy efficient than conventional HVAC units.

Are conventional HVAC units energy efficient?

Regarding the cooling apparatus, conventional HVAC units are about as energy efficient in the summer as heat pumps. However, in the winter, due to the previously discussed factors, a heat pump is more energy efficient (in climates that stay generally above 40 degrees Fahrenheit) and may actually yield a tax incentive if you install one.

How much does a conventional system cost?

A conventional system costs roughly five percent less than a heat pump, although they undergo less wear and tear than a heat pump as well, which adjusts the overall cost of installation and repair. We recommend speaking with a Gorman Mechanical HVAC professional who can help you determine which unit is best for you and will save you the most money.

Gorman Mechanical installed a brand new cooling and heating system in my home. The replacement unit was larger and more energy-efficient. Our house has never been cooler and our energy bill even went down…. I highly recommend them and their services.

I had an issue with my A/C unit not cooling properly. The technician, Stacy, arrived during the time frame I was given, and I received a phone call about 30 minutes prior to his arrival, letting me know he was on his way. He was very professional and conscientious in figuring out and explaining the issue to me. He work was complete in a little over an hour and my house is cool once again! I will definitely refer Gorman Mechanical to others.

A Gorman technician came over to set us up with a new A/C unit and he did a phenomenal job. He was very up front with any cost and got our install scheduled in one day. He did a great job at getting me the unit needed without running the price through the roof.

I met with Gorman Mechanical’s Sales Manager. When he came out I had a bad taste in my mouth due to some misrepresentations made by another company that happened to be A rated on Angie’s List. Because of this I’m certain I was on the defensive and asked a million questions. He was very patient and took plenty of time answering all my questions. He was very knowledgeable and helped educate me on my options and the advantages/shortfalls of each. When I came to the actual bid, I felt it was very competitive compared to other bids I’d received. I felt so well informed and confident at that point I cancelled two other appointments I’d made for that day and signed up with Gorman Mechanical. He was able to promptly arrange a great deal on financing the bulk of the cost, leaving me to pay out of pocket for a couple last minute additions (extended warranty/Reme Halo). They did not want this until installation was complete. A couple days later they installed my new system and I’ve been very happy with it. Shortly after installation I had several other questions about maintenance and a small amount that was overcharged upon installation. He was very responsive answering my questions and arranging for a prompt refund check to be sent. Fortunately, it isn’t often that I need to spend so much money on an important purchase like this, but I felt very confident with my decision and going through the process with him and Gorman Mechanical made it painless. I wouldn’t hesitate to recommend Gorman Mechanical to friends and family.

The repairman, Tim H., was prompt and courteous. I explained that he was a second opinion for our 21-year-old AC. The first company said that I would need 2 parts totaling $600 plus a coil that they would have to send a salesman out to quote me a price. Also first company was suggesting that I really needed whole new system. After inspection, Tim showed me how a part was wired the wrong way and he replaced a compactor and repaired a burnt wire. 2 lbs Freon were added. Total cost was retail: $217.75. I had a warranty so I paid less but what a difference in $600.00+ and $217.75! AC is working fine now. And we didn’t have to buy a new system. Thanks, Gorman Mechanical and Tim H.! The world needs more honest repairmen like you!
