10 Best HVAC Companies in Dartmouth, MA

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting old, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:

• Frequent breakdowns and need for repairs
• Higher than normal energy bills
• Corrosion, rust, or cracking
• Thermostat malfunctions or temperature control issues
• Refrigerant leaks
• Strange noises when turning on
• Poor air circulation or uneven heating/cooling
• An HVAC system that's over 15 years old

If you're experiencing any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Dartmouth

The cost of HVAC installation or maintenance will vary depending on the kind of unit you have. Common types of HVAC units include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either electricity or gas for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and the outdoors. They don't create their own heating and cooling, so they work more efficiently in more mild climates.
• Packaged heating and air: Packaged HVAC systems are good for smaller houses. Packaged systems consist of a single combined heating and cooling unit, usually located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complicated and can require different maintenance services. Fees for common services are as follows:

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your HVAC.

• Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both helps minimize the amount of work your HVAC system must perform.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, grills, and condenser fan blades clean enables your HVAC system to function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice it starting to get dirty.
• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the outside areas of your HVAC system as much as possible.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on what kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled at the state level.

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

It's also important 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 a company's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You want to hire a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new energy efficiency, features, model, brand, and estimated installation time. Before signing paperwork, 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

Reliable HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection within your budget.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.
