7 Common HVAC Problems

HVAC issues are a cause of frustration for any homeowner. Whether you’re not getting sufficient airflow from your vents or notice a musty smell when you turn on your HVAC system, the team at Bovio Rubino Service can help find a long-lasting and efficient solution. 

Our comprehensive HVAC services cover a wide range of issues, from the everyday to the emergencies. Keep reading to learn about 7 common problems South Jersey homeowners experience with their heating and cooling systems.

  1. Poor Heating & Cooling Distribution

When you experience inconsistent temperatures in your home and certain rooms are always too hot or cold, there’s a good chance the culprit is actually not your HVAC—but your ductwork. Leaky or improperly sized ducts can lead to a variety of comfort issues and energy waste. 

The team at Bovio Rubino Service can help find a solution to make sure everyone in your home stays comfortable with either our HVAC zoning services or installation of a ductless mini split for supplemental heating and cooling. 

  1. Loud Noises

Strange sounds coming from your HVAC system should never go ignored as they can be a sign of leaks or other serious malfunctions. Here are some of the most common noises an HVAC will make and what problems they can indicate:

  • Hissing – This can mean a refrigerant leak in your AC or a punctured duct
  • Squealing or screeching – This usually means that a belt within your HVAC needs to be replaced
  • Buzzing and clicking – This can indicate a compressor issue and should get inspected as soon as possible

Bovio Rubino Service can help identify the source of strange sounds coming from your HVAC and help get your system up and running again with our heating and cooling repair services. 

  1. Mildew & Mold Buildup

Mold and mildew thrive in the damp and dark areas of your home, making your HVAC system susceptible to its growth. Some signs to look for to determine if mildew is present in your HVAC or your duct system include musty smells, condensation, or leaks, as well as allergy symptoms like sneezing or a runny nose.

If your HVAC or duct system has grown mildew, call the experts at Bovio Rubino Service. Our team can determine the severity of the problem and solve it with duct cleaning and other indoor air quality services. 

  1. Poor Insulation & Air Leaks

Insulation and air sealing may not be the first thing that comes to mind when your HVAC is having issues, but they have more of an impact than you might think. In fact, upgrading your home’s insulation and sealing gaps and cracks can significantly reduce your energy waste and save around 20% of your heating and cooling costs!

With a home energy audit from Bovio Rubino Service, we can pinpoint exactly where your home is wasting energy through poor insulation and air leaks. We can then help improve your whole home performance with our insulation and air sealing services. 

  1. Malfunctioning Thermostat

When your heating and cooling systems are constantly running without reaching your desired temperatures, your thermostat could be to blame. 

Make sure to always check batteries and your system settings before calling for professional HVAC repairs—but in the case your thermostat is broken, Bovio Rubino Service is there to help. We can install a new, smart thermostat with programmable settings that save you money on your energy costs. 

  1. Dirty Air Filter

Dirty air filters are one of the most common causes for a wide variety of HVAC issues—from poor airflow to frozen evaporator coils. Your system’s air filter should be changed every 30-90 days, but may need it more often if your household is sensitive to allergens, you have pets, or have older HVAC equipment. The team at Bovio Rubino Service will check your air filters during our annual tune-ups!

  1. Lack of Maintenance

Regular maintenance is the most important thing you can do to keep your HVAC running efficiently for years to come. Whether you have a furnace, traditional air conditioner, or a high-efficiency heat pump, maintenance visits at least once a year are crucial to its operation. 

You can get peace of mind by enrolling in our Maintenance Protection Plans! We offer 4 different levels of plans in order to fit any budget, all of which come with several benefits to your HVAC, such as:

  • Improved performance
  • Longer service life
  • Less need for repairs
  • Improved energy efficiency

Applications for the 2026 Bovio Rubino Service Young Women’s Leadership Conference are Live

South Jersey Rising Junior and Senior High School Young Women are Encouraged to Apply

Voorhees, New Jersey – April 1, 2026 – Young women going into their junior and senior years of high school who are thinking about their futures are encouraged to apply to attend the 2026 Bovio Rubino Service Young Women’s Leadership Conference on Wednesday, July 15 in Voorhees.

The application to attend the Young Women’s Leadership Conference is now live and available through Friday, May 1 by midnight. The Conference is part of “LeadHERship in ’26,” this year’s Bovio Rubino Service community cause which “seeks to advance the opportunities of young women through career readiness, entrepreneurship, community betterment and a personal health and wellness mindset.”

Speakers, workshops and discussions are part of the one-day Conference in July. The opportunity to present an original idea that betters the community after the Conference will be presented to the Conference attendees.

Investing in young women is an idea close to the heart of Bovio Rubino Service president Angela Rubino Hines, a Mom of two young women and a leader amongst very few women in the HVAC and Plumbing service industry. In 2025 Hines was named one of the country’s “Top 12 Women in HVAC” by ACHR News. While she’s humble about the success she has achieved it inspires her to encourage the next generation of women leaders.

“We look forward to investing in young women this year at our Conference, through creative programs with our team members and through partnerships with nonprofit organizations. ‘LeadHERship in ’26’ is our way of giving back and inspiring the next generation of women leaders right here in South Jersey where we live and where our customers live.”
