In many instances, it’s unavoidable to have your heating system or air conditioner stop working for any number of reasons.

However, as a homeowner, there are things you can do to help keep your HVAC system in top working order, and you can save money by not making these common mistakes.

  1. When Was the Last Time You Changed Your Air Conditioner Filter?

The filter for your air conditioning unit is one of the most important components. It is what keeps dust and other debris from clogging the system and causing it to break down.

Your air filter should be changed regularly. How often it needs to be changed depends on several factors: the time of year and how much dust, pollen, etc. is in the air; what type of HVAC system you have; and how much you run your air conditioner or furnace.

Your local East Texas AC and heating company should also change your filter when performing HVAC maintenance.

  1. Are Your Vents and Ducts Free of Anything Blocking Them?

A very common mistake homeowners often make is accidentally blocking vents, ducts, or even the outdoor unit.

If the unit cannot intake air the way it’s supposed to, it will start to break down. If you notice that your HVAC unit isn’t working properly, one way you can troubleshoot is to check and make sure there is nothing blocking any part of the unit.

Check the outside unit for bushes, leaves, or even yard furniture that might be causing a blockage. Check inside for ducts or vents that may have accidentally gotten covered.

If your HVAC unit isn’t working properly, before you call an AC repair company in Texas like ETR, do your own inspection of the ducts, vents, and outside unit and remove any blockages to see if that fixes the issue.

 

  1. Are You Sure You Have the Correct Sized System?

One common mistake homeowners can easily make if they don’t work with a professional HVAC company is installing the incorrect size unit for their space. This could mean a unit that’s either too big or too small.

The correct size unit for your home or commercial space should be assessed by a professional HVAC technician. If you have the wrong size unit, it impacts the unit’s efficiency, your home’s comfort, and your home’s energy use.

An improperly sized HVAC system could cause you to pay more in utility bills because the unit won’t be working as it should.

Systems that are too small cause the unit to overwork, which means on really hot days your air conditioner will be working overtime. Having the incorrect size is also very hard on the system itself, causing it to wear out and for you to need a new air conditioner sooner than expected.

When a system is too large, it uses more energy than is necessary, it doesn’t control the humidity properly, and it often short cycles.

When installing an air conditioner, it’s important to work with professionals to ensure the space is properly measured, the ductwork is capable of handling the system, and there is proper and adequate insulation used.

  1. Do You Know How to Properly Use Your Programmable Thermostat?

If your AC unit isn’t working as it should, you might need to make sure you’re using your programmable thermostat properly.

Not using the thermostat as it should be used is a common mistake many homeowners make. If you’re not sure how to properly use your thermostat, contact a local East Texas HVAC expert and have them show you. It will make a big difference in your home’s comfort, the efficiency of your HVAC unit, and how much you’re paying in utility bills.

Sometimes people don’t know how to use the smart features on their thermostat, which can be very helpful when it comes to temperature regulation.

Another common mistake is confusing the “Auto” and “On” settings.

Additionally, make sure you set the temperature when you leave home so your unit isn’t heating or cooling an empty house.

 

  1. Don’t Ignore System Warning Signs and Always Schedule Regular Maintenance

One of the most common mistakes people make when it comes to their HVAC unit is ignoring warning signs until it’s too late.

In addition, many people wait until their unit is breaking down before calling an HVAC professional.

Regular HVAC maintenance with state-of-the-art products and diagnostic equipment saves you money in the long run. Details such as seasonally having your ductwork cleaned can make a big difference in keeping your HVAC unit running properly.

If you notice that your air conditioning or furnace is producing warning signs such as strange smells, sounds, dripping water, or running overtime, it’s crucial you contact a trusted East Texas HVAC professional and have your unit inspected.

One of the best things you can do for your HVAC system is sign up for a professional HVAC maintenance program.

Regularly scheduled maintenance and seasonal inspections, including carbon monoxide inspections, furnace check-ups, and HVAC system maintenance, will save you money in the long term.
