7 Common HVAC Mistakes Owners Make

PUBLISHED: September 15, 2015 6 MINS READ

Heating and air conditioning units make us feel nice and comfy. No matter what the temperature is outside, whether it’s too hot or too cold, HVAC units help us relax inside our homes. So, as owners of HVAC systems, we want to keep our heating and air conditioning units in good working condition. To do that correctly typically involves regular maintenance and occasional repairs. There are times when we make mistakes though, some of those being very common. Making mistakes with the maintenance of HVAC systems will typically reduce those systems’ performance and efficiency. We all make mistakes. But, how we handle them is the crucial thing. In order to correct these mistakes, you first need to know what is going wrong. To help you out, we have covered the 7  common HVAC mistakes owners make. After learning about these you should know what to avoid, while effectively dealing with your HVAC units.

Common Mistakes HVAC Owners Make

1. Old HVAC units

Like all other mechanical systems, the performance of HVAC units reduces with time.  But if you maintain your HVAC system properly it does tend to work well longer. People often ignore this fact. Moreover, older HVAC systems are not equipped with modern technology. Their construction and optimal efficiency become obsolete over time. Because of this, some homeowners trade an older system for a newer one rather than dumping good money into costly repairs up system upgrades. Also, you should know that HVAC installation mistakes can cost you dearly.

2. Playing with the HVAC settings

Many people constantly change the settings of their HVAC systems. They fiddle with the controls and settings of their HVAC systems, day in and day out. But they don’t realize that this can harm the overall performance and efficiency of their HVAC units. It is recommended that you set your HVAC systems to a particular setting, which will work for all temperatures. 

The settings should remain stable. This way the HVAC unit will adapt to your comfort level. You can also adopt other measures to control the temperature of your home. For instance, in winters, you can add another layer of clothing or use a blanket to keep yourself warm, instead of changing the settings of your heating unit. This is one of the common mistakes HVAC owners make.

3. Continuously running your HVAC systems

Some people continuously run their HVAC units. Some homeowners leave their air conditioning and heating units on when they go out so that when they return home they can find their homes at the preferred temperature. When it is very heat or cold, this approach to maintaining a constant, comfortable temperature may take a toll on your HVAC system. 

It also uses a lot more energy, resulting in huge electricity bills. Instead of this approach you might find a tolerable temperature and maintain that until you return home. Or you can opt for a programmable HVAC system with time-specific temperature controlling options. Such units allow you to pre-program the settings and govern how your HVAC unit operates when you are not at home so that when you arrive home you can feel comfortable without constantly running your HVAC unit. This is one of the common mistakes HVAC owners make.

4. Choosing the wrong temperature for the time of year

Keeping only one particular setting of your HVAC system throughout the year is also not good. Seasonal high temperatures or low temperatures can put excessive stress on the system. Keeping your home around 72 degrees Fahrenheit may be desirable, but it may not be ideal year round from the point of view of maintaining your HVAC system. 

If you are not sure of the temperature that is safest to maintain for your particular system at various times of year you should ask the company or technician maintaining your system for that advice. This is one of the common mistakes HVAC owners make.

5. Forgetting the V in HVAC

Yes, many people forget about the crucial V in HVAC. The V stands for ventilation. People oftentimes overlook the IAQ (Indoor Air Quality) of their homes. Kitchens and bathrooms are the most common places in a house that may be poorly ventilated. Depending on your region’s climate your house may suffer from high humidity in addition to having ventilation issues. 

Such homes require mechanical systems to deal with excess humidity. Excess humidity can cause your system to work much harder than is ideal for its expected operational life. And improper ventilation, even without extra moisture in the air can seriously affect the performance of the system. Make sure that your HVAC units incorporate adequate ventilation with the 3 essential pressures– positive, negative, and balanced pressure.

6. All HVAC systems are not created equal

Every house has a different structure and architecture. Modern homes tend to be much larger than ones from the past. HVAC systems have also changed. But you should never assume that the HVAC system in your home is the exact match to your home size and other unique factors. If you never seem to find a comfortable balance between the indoor temperature and the electric bill you may want to speak with an HVAC professional. Make sure that your HVAC unit or units are sized properly. And don’t skimp on costs at this point. Going with the best HVAC service and sales outlet in your area is wise.

7. Forgoing annual HVAC inspections

People often ignore the fact that they need to call on professionals once in a while, for maintaining and repairing their HVAC units. Remember to schedule an appointment with an HVAC technician, at least once each year, in order to ensure proper functioning of your HVAC unit. 

Twice per year may be better, and your local service company may offer pre-paid plans with discounts for paying in advance. Paying in advance may also help to avoid forgetting to schedule the service calls. And don’t fall into the trap of trying to save money at the expense of the longevity of your HVAC system. You get what you pay for. 

You might save some money by choosing the cheapest HVAC service contractor, but spend a lot more when the system starts to break down due to cheap parts, cheap filters or improper maintenance.

We hope you have learned a few valuable things here. Owning a home can be a daunting task when you really start to recognize all the details involved in maintaining it. But even when you don’t know a lot personally about the house or its systems you can always save yourself future problems by having a trusted professional to give advice and to do the actual work needed to maintain things around the house. 

For the HVAC there is no substitute for a great company or individual contractor, one with a good reputation in your area. Ask your friends or family members if you aren’t sure which company to choose. And just as this website provides reviews for home warranty companies, you can find great websites that you can trust which have thousands of reviews on HVAC installation and service companies.

What do HVAC Contractors Do?

HVAC Contractors specialize in the installation and maintenance of HVAC systems. HVAC is the abbreviation for Heating, Ventilation, and Air Conditioning. HVAC contractors understand the market to ensure that you purchase the right equipment for your needs.

Why is HVAC important?

HVAC is important as it helps with the heating and ventilation of the home and office buildings. This is why specialized HVAC systems are installed. Heating, Ventilation and Air Conditioning (HVAC) systems help maintain the safety and comfort in a building.

How do you maintain an HVAC system?

  • Inspect, Clean, or Change Air Filters Once a Month
  • Schedule Seasonal HVAC Maintenance
  • Clear the area around your HVAC system
  • Clean Evaporator and Condenser Coils
  • Maximize Air Flow
  • Install a Programmable Thermostat

What is preventive maintenance in HVAC?

Cut energy bills: With preventive maintenance, your HVAC system runs close to its best efficiency. Most components of the HVAC system are quite expensive and this is why you should invest in annual maintenance to keep them covered under a home warranty. This can save you money in the long run.

Are HVAC maintenance plans worth it?

Homeowners usually do not buy HVAC service contracts because of the cost. Contracts cost anywhere between $150 to $500 per year and this depends on the services offered. In case you go five years without a major repair then you would be paying $250 per year for the contract and this may not be worth your while.
