Thermostats with text: "control warmth with programmable thermostats"

The exceptional reliability of HVAC equipment tempts homeowners into ignoring the importance of HVAC maintenance. It’s easy to think very little about an HVAC system until something goes wrong. But soaring utility bills or a lack of air conditioning on a sweltering day gets our attention in a hurry! HVAC maintenance is so important because it can help prevent these problems (and HVAC emergencies). Following our HVAC preventive maintenance checklist will help you save money while boosting your family’s comfort and health.

Benefits of HVAC Maintenance

It’s difficult to overstate the importance of HVAC maintenance. Regular equipment maintenance provides the following benefits:

  • Reduces Utility Bills: Regular HVAC maintenance keeps your equipment working at peak energy efficiency, costing you less to use it.
  • Prevents Costly Repairs: Routine maintenance can extend the life of your system and prevent damage leading to costly repairs.
  • Fulfills Warranty Requirements: Many HVAC warranties run for 12-15 years, and they can save you significant money on repairs. However, most warranties require proof of regular maintenance for a claim to be paid.
  • Improves Air Quality: Your HVAC system does more than heat and cool your home. It filters out dust, mites, and other allergens and pathogens, leaving the air in your home cleaner and healthier for all to breathe.
  • Improves Safety: The National Fire Protection Association reports that over 44,000 house fires are started by faulty heating equipment every year.
  • Provides Worry-Free Comfort Year-Round: Routine HVAC maintenance ensures your heating and cooling system is always ready when you need it.

When considering your family’s health, comfort, and budget, you can see why HVAC maintenance is important.

HVAC Maintenance FAQs

Now that we have covered why HVAC maintenance is important and the tasks that should be completed, let’s take a look at some of your questions.

What happens if I avoid HVAC maintenance?

If you skip regular HVAC maintenance, you risk higher utility bills due to a loss of energy efficiency. Small problems are more likely to grow into large ones requiring costly repairs. You will need to make significant repairs more often or replace the equipment sooner; the air quality and comfort of your home will be compromised. These are some of the top reasons why HVAC maintenance is important.

How much does HVAC preventative maintenance cost?

Annual preventative HVAC maintenance typically runs between $75 to $200, depending on how much needs to be done. Charging the refrigerant costs more. Between the savings on your utility bills and avoiding costly repairs, HVAC maintenance pays for itself.

Is HVAC maintenance worth it?

Yes. The importance of HVAC maintenance is demonstrated in both monetary savings and improved health and comfort for your family. Well-maintained equipment is less expensive to operate, avoids costly repairs, and prolongs the life of your system. Heating and cooling are more efficient and less expensive, and your indoor air quality is improved.

How often should you maintain your HVAC system?

Annual HVAC maintenance is necessary to avoid costly repairs. But to ensure your system works at peak efficiency all year long, we recommend that you have the heating system fully checked in the fall and the air conditioning system checked in the spring.
