10 Best HVAC Companies in Dedham, MA

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can pinpoint problems and determine whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Dedham

Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of internal units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps move hot and cold air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more moderate climates.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in an attic or basement. This unit is typically space-saving, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also depends on what kind of work being done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your HVAC system.
• Change filters regularly. Changing your air filters or washing them every 30–90 days allows efficient air circulation through your HVAC system. Also try to keep debris from accumulating on the outside components of your HVAC.
• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, grills, and ductwork clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual 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.

The state of Massachusetts doesn't have state-level HVAC contractor licensing requirements. However, HVAC technicians who work on certain cooling jobs 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 HVAC contractors have any local licensing requirements. You should also check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Choose a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should detail the exact parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to guarantee everything is working correctly. When replacing your HVAC system, ask the contractor to describe the new features, estimated installation time, model, brand, and energy efficiency. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Trustworthy HVAC companies stand behind their work with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Get written quotes before beginning any HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
