10 Best HVAC Companies in Norfolk, MA

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or getting old, you might need an HVAC contractor for repairs or replacement. Watch for these common indicators that your system requires expert attention:

• Temperature control issues or thermostat malfunctions
• Strange noises when turning on
• Rust, corrosion, or cracking
• Refrigerant leaks
• Unusually high energy bills
• Frequent breakdowns and need for repairs
• Uneven heating/cooling or poor air circulation
• An HVAC system that's over 15 years old

Schedule an inspection if you notice any of these issues. A local technician can assess your system, detect problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Norfolk

The price of HVAC installation or maintenance changes depending on the type of unit you have. Common varieties of HVAC units include the following:

• Split or mini-split: If your home lacks the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have interior units in each room to regulate temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the benefit of being able to draw power from either electric or gas sources.
• Heat pump: Heat pumps move hot and cold air between your home and outside. These systems don't make their own heat or AC, so they work more effectively in milder climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. They have a single heating and cooling unit, normally in a basement or attic. This unit is often small, cost-effective, and easy to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complicated and may require different kinds of maintenance. Costs for common services are as follows:

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your system.

• Keep your system clean. Cleaning your ductwork, indoor evaporator coil, grills, and condenser fan blades regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.
• Change filters regularly. Air flows most effectively through your HVAC system when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the external sections of your HVAC.
• Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the frequency with which you need to run your HVAC.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary training and licenses. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

Massachusetts doesn't have state-level licensing requirements for HVAC contractors. However, HVAC technicians who do certain cooling work may need a Refrigeration Technician License for larger projects.

It's also a good idea to check with your city or municipal government to find out if there are any local licensing requirements for HVAC contractors. You should also check reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about great customer experiences.

Understand Work Details

Always make sure you understand the details of a planned project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are completed to verify that it’s working properly. When replacing your HVAC, have the contractor explain the new estimated installation time, brand, model, energy efficiency, and features. Before work starts, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Reputable HVAC companies stand behind their services with warranties. Look at warranties from different companies, bearing in mind that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote covers costs for both labor and materials. Ensure that you understand all terms before signing the contract.
