What are the benefits of updating your HVAC unit?

Believe it or not, most customers forget that updating their HVAC unit is essential. Why? Well, if it’s well-maintained, they won’t notice a problem.


The last thing you want to do is wait until it doesn’t work entirely before you replace it.


You need to ensure your system is working well for you, so here are six great benefits to updating your HVAC unit with professionals here at TMC!

Comfort Control. An upgraded system allows you to keep your home at an optimum temperature for the whole family. You can program the new system to adjust to your needs, with multiple thermostats in the house. The modern unit will pay for itself in the money you’ll save on energy, and you don’t compromise your comfort.


New Thermostat Programs. Most new HVAC replacement units come with programmable thermostats so you don’t have to worry about coming home from work to a cold house. You can even upgrade your HVAC system to be controlled by a smart thermostat, allowing you full control from anywhere.


Better Air. An HVAC repair can often show that there was dusty, stale air being pumped into the room. With an HVAC replacement, you will be able to breathe better with cleaner air. This will offer a significant difference in your health and your home. With better efficiency and better motors, you get constant, high-quality airflow. 


A Quiet Option. Is your HVAC whirring noisily? It’s not supposed to do that. You will hear a big difference in sound when you upgrade your HVAC unit. 


Environmentally-Friendly. You can upgrade your HVAC to a new unit that is better for the environment. A high-efficiency system is going to use less energy than one that is in dire need of repair or is aging badly. You’re going to save money this way, while also reducing your carbon footprint.


New Warranty. When you upgrade your HVAC system, you are investing in something new. Ask our team at TMC what warranty options are available for your new investment.

Heating Repair and Replacement FAQ

When Is It Time To Replace My Heating Unit?

If you are having regular appointments with our experts at TMC, then you’ll know the right time for an HVAC replacement as we always repair first and replace when necessary.

However, it’s essential to recognize the signs and symptoms of a dying unit. Let’s look at five signs:

  1. It’s Over a Decade Old. Your HVAC unit is not designed to last more than ten years, so when it gets close to this point, you may need more expensive repairs. 
  2. It’s No Longer Efficient. It can cost you a lot of cash to operate your HVAC if it’s tired. A tired unit uses more energy, and you need to ensure your costs are cut back. A newer, more efficient unit will do this for you.
  3. The Repairs Are Expensive – And Frequent. You shouldn’t need constant HVAC repairs. In fact, it makes financial sense to have an HVAC replacement than the continuous payout for repairs. Our experts can recommend the best HVAC systems and brands for you to make an informed choice.
  4. It Breaks Down – Often! You shouldn’t be waiting for your HVAC unit to stop working. Ask our team today what to do if you notice that it’s breaking down regularly. You may as well invest the money in a new unit instead of paying for frequent repairs.
  5. Your Home Is Uncomfortable. You shouldn’t have a hard time keeping your home cold or warm. If you are struggling with your daily comfort, then you need a new system.

When Is The Best Season For a HVAC Replacement?

The best time to repair your HVAC is any time it’s broken, but when it comes to a replacement, you should look at the end of September – November.

Fall months are the best time to shop around, and you would have just had the summer heatwave and heavily used your air conditioning. You’re about to switch to warmth mode for the winter, so choose fall for a replacement so that you can bridge the gap easily between seasons.

Do You Know Your HVAC Parts?

To have an efficient HVAC system, you need to know what it’s made of. This is a device that’s responsible for the heating, air conditioning, and ventilation of your home.


If you know all of the components, you can learn what’s stopped working when things go wrong!


Not only will this help you when describing the issue to us, but we can also often repair and replace your system faster.


Let’s take a look at the essential components of your HVAC system:


  1. Thermostat. First, the thermostat is the most visible part of the system. It’s usually in an accessible room of the home and evident on the wall. It’s there where you set the right temperature you want for each room for the home, and you can use this to program different temperatures for different parts of the house. Once you set the temperature, your home will be maintained there until you change it.
  2. Furnace. A vital component of the whole HVAC system, the furnace is the largest of all of them. You should have space in your home for your furnace to go so that it can run properly with enough ventilation. Usually, the furnace goes in the attic or in the basement. It needs enough space around it for an engineer to inspect it when necessary.
  3. Heat Exchanger. Inside the furnace, the housing unit is a heat exchanger. When the thermostat is turned up for more heat, this is activated, and the cooler air is pulled in and converted to warmer air. It then circulates this air back out of the house.
  4. Evaporator Coils. These are the opposite components to the heat exchanger, acting as a coolant for the air when the thermostat is set to air conditioning. It’s inside the metal enclosure outside the furnace, and it produces cold air to go through the ducted vents.
  5. Condensing Unit. Connected to the evaporator coil, this is installed by our experts for you outside of the home. It’s filled with refrigerant gas, and when it’s been cooled to a liquid via the heat exchange with exterior air, the unit will pump liquid to the evaporator coil to become a gas once more.
  6. Refrigerant Line. The lines carry a refrigerant substance to the condensing unit, which is then vaporized in the form of gas before returning to the evaporator coil as a liquid. These are made from metal and are great at keeping the refrigerant cold.
  7. Vents. These outlets around the house transfer the air you’ve cooled or heated from the ducted system into each room. They are made of a safe metal that won’t burn or freeze your hand to touch, and they’re always by the ceiling. They move the air downward to be able to heat or cool the whole room and work to ensure the entire place is heated or cooled correctly.
  8. Ductwork. The ductwork in your home transports the hot or cold air from room to room. These are made of lighter materials, and they are designed to be sturdy. You will find some are made of steel, others with fiberglass but they all work the same way.
