HVAC Service and Maintenance in South Maryland

When it comes to your HVAC system, preventative maintenance is crucial. Routine servicing keeps your heating and cooling system running efficiently for years to come. Preventative maintenance and annual tune-ups can alert your service technician to minor problems that — if left untreated — could lead to more costly repairs in the future. It can be a challenge to know when it is the right time to call a technician— SMO Energy can help. 
What Is Involved in HVAC Maintenance?

What Is Involved in HVAC Maintenance?

Certified HVAC technicians check several different parts of your heating and cooling system during a tune-up. During an annual tune-up, our technicians will:

  • Inspect your system: A technician will perform a visual inspection of both the interior and exterior of your heating and cooling system. During the inspection, they will look at the fan blades for signs of damage as well. The technician will also confirm that the HVAC unit starts and stops the way it should and that all parts are working correctly. They may also listen for any unusual sounds coming from your system.
  • Clean your equipment: A tune-up includes clearing away any debris from the interior and exterior of your HVAC unit, such as dirt, dust or leaves.
  • Change the filter: Air filters are the key to clean air. If necessary, the technician will change your system’s filters during the tune-up, ensuring your home has access to good indoor air quality at all times.
  • Check the connectivity: A connectivity check includes ensuring everything is wired correctly and connections are snugly fit. Not only does this keep everything working the way it should, but it keeps your home safe, too.
  • Calibrate the thermostat: Your technician will make sure your thermostat is functioning correctly. A working thermostat can help you keep your home comfortable at all times.
  • Add lubrication: Lubrication keeps all of your unit’s moving parts operating smoothly and with as little resistance as possible.

If you have specific concerns about your heating and cooling system, let your technician know before they begin your inspection. They can investigate the source of the problem. If the technician finds that your system needs additional repairs beyond the maintenance involved in the tune-up, they will discuss the costs with you and let you know what your options are.

Benefits of Regular HVAC Maintenance in Southern Maryland

Maintaining your HVAC system offers several benefits, including:

  • Ensuring everything is working well: Regular maintenance tune-ups keep your equipment operating at full-performance.
  • Extending your equipment’s life: Addressing minor issues and repairs as they arise, rather than ignoring your HVAC unit, can help your system last longer.
  • Keeping your equipment safe: Sometimes a problem with your HVAC unit, like an electrical issue or poor air quality, could be a safety risk. Regular maintenance is the best way to keep your home safe.
  • Saving you from potentially costly repairs: Addressing minor heating and cooling repairs as they come up, instead of letting the problems get worse, may save you from an expensive repair or replacement in the future.
  • Keeping your energy costs minimal: When your HVAC unit is not working the way it should, you could see a rise in your energy costs. Keep those costs minimal by scheduling regular tune-ups.

A big part of preventative maintenance goes beyond annual tune-ups. It also includes scheduling an appointment with your technician anytime you have a concern or notice something unusual with your heating and cooling system.

FAQ: HVAC Services and Maintenance

Want to know more? Below you will find some frequently asked questions regarding preventative heating and air conditioning maintenance and SMO Energy’s HVAC services.

1. What Are HVAC Services?

HVAC services include the installation, maintenance, repair and replacement of your home heating, ventilation and air conditioning system.

2. What Should I Look For in an HVAC Service Provider?

When you are looking for quality HVAC services, it is a good idea to check business credentials and read any customer testimonials. Rather than trying to service your HVAC system yourself, a certified technician should always do HVAC repairs and installations. High-quality HVAC servicers are well-trained, knowledgeable and take the time to address each of your concerns.The technicians who work for SMO Energy are all North American Technician Excellence (NATE)-certified, meaning they have passed a rigorous, closed-book exam and demonstrated comprehensive working knowledge of HVAC equipment. To maintain their certification, our technicians complete 2,700 hours of training annually.

3. How Long Do HVAC Units Last?

HVAC units typically have a lifespan of 10-15 years. However, the lifespan of your heating and cooling system depends on several factors, including regular maintenance and frequency of use. That means there may be times when you need to replace your HVAC unit sooner. Additionally,there may be instances where only a few parts of your unit will need to be replaced. A couple of things that can indicate it is time to replace your entire HVAC unit include:
  • Frequency of repair: If you have had to call a repair technician to address problems with your HVAC unit several times over the past few years, it may be time to consider replacing your system.
  • Rising energy costs: If you have noticed an unexplained increase in your energy bill,the efficiency of your HVAC unit could be to blame, and it may be time for a replacement.

4. How Much Does It Cost to Service an HVAC System?

The cost of servicing an HVAC system depends on a combination of factors, including the size and type of HVAC unit, whether the system is being repaired or replaced, the age of your unit and the overall nature of the service.

5. What Is Preventative HVAC Maintenance?

Preventative HVAC maintenance means taking the steps necessary to ensure your HVAC system continues to run smoothly and efficiently before a repair is needed. Preventative maintenance includes scheduling annual maintenance tune-ups, keeping track of when filters need to be changed and being proactive about any changes you experience with your HVAC system. Successful preventative maintenance includes notifying your HVAC equipment service provider of any problems or concerns you have regarding your heating and cooling.

6. Why Is Preventative Maintenance Important For HVAC Systems?

Being proactive about your HVAC unit’s health is the best way to ensure seamless operation. By scheduling routine maintenance on your system and addressing issues as they arise, you are keeping your HVAC system in prime shape. Not only does this prolong the life of your HVAC system, but it may save you from potentially more substantial and expensive damages that tend to arise from an ignored HVAC unit. Plus, taking preventative care of your HVAC system helps to reduce the likelihood of breakdowns, meaning you, your family and your home remain comfortable.

7. How Can Preventative Maintenance Help Extend the Lifespan of Your HVAC Equipment?

Routine maintenance can alert technicians to any problems — or potential future problems — with your HVAC unit. Without the eye of a trained professional, some of these issues could escalate further, causing a breakdown of your HVAC unit. If you wait until your system breaks down to have it repaired, it tends to be more costly to fix or may even result in total system replacement.

8. Does SMO Energy Offer Emergency Servicing?

Yes, SMO Energy understands the importance of a warm home, especially in those cold winter months. Should your heating system fail in the middle of the night or over the weekend, SMO Energy will send an emergency technician to your home for an additional fee.

9. What Does It Mean to Be a NATE Certified Technician?

NATE stands for the North American Technician Excellence program. SMO Energy’s technicians are all NATE-certified. NATE is the only program in the United States that uses a closed-book exam, administered by a third-party, to test technicians’ working HVAC knowledge. NATE-certified technicians also need to complete continuing education each year to maintain their certification.

10. When Should I Call an HVAC Technician?

When something happens with your HVAC unit, it can sometimes be difficult to know if the issue warrants a service visit outside of your annual tune-up and maintenance. Here are some signs that you should definitely schedule an appointment with your HVAC technician:

  • Unusual sounds or smells: If you notice a strange rattling or popping sound or notice an abnormal odor, it is time to call your HVAC technician.
  • Lack of airflow: If your HVAC unit is not putting out as much air as it used to, this is an indicator that something could be blocked internally. Certified technicians can locate the source of the issue and fix it properly.
  • Incorrect temperatures: If the temperature on your thermostat does not appear to match the temperature you are feeling in your home, it could be as simple as an issue with the thermostat. It could also be a sign of a more significant problem with the unit itself.
  • A noticeable change in air quality: Do you feel dizzy, sneeze more than usual and experience other symptoms while indoors? If the symptoms seem to clear up when you go outside, it’s likely poor air quality inside is to blame — and your HVAC system could be the cause.
