10 Best HVAC Companies in Hanover, MA

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or getting old, you might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:

• Corrosion, cracking, or rust
• Uneven heating/cooling or poor air circulation
• Strange noises when turning on
• Refrigerant leaks
• Frequent breakdowns and need for repairs
• Unusually high energy bills
• Temperature control issues or thermostat malfunctions
• 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 identify problems and determine whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Hanover

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have indoor units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps move warm and cool air between your house and the outdoors. They don't create their own heating and cooling, so they work more efficiently in more moderate climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically compact, energy-efficient, and straightforward to maintain.

The price of HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is 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. 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 amount of work your HVAC system needs to do.
• Keep your system clean. Keeping your condenser fan blades, ductwork, grills, and indoor evaporator coil clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system whenever it begins to look dirty.
• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
• Change filters regularly. Air flows most effectively through your HVAC system when you replace or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Get quotes from three or more HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians who "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 by the state.

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

It's also important to check with your city or municipal government to learn if there are any local licensing requirements for HVAC contractors. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can aid your decision as well. Choose a provider with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Make sure you understand the details of your project before starting. If HVAC repairs are required, have your provider detail which parts require replacement and why. Get confirmation that your technician will clean and test the system after the repair to ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, model, brand, features, and estimated installation time. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Reputable HVAC companies back their services with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

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