10 Best HVAC Companies in Nashua, NH

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Nashua

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

• Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have indoor 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 transfer hot and cold air between your home and the outdoors. They don't generate their own heating and cooling, so they work best in more mild climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined heating and air conditioning unit, typically located in a basement or attic. This unit is typically space-saving, cost-effective, and easy to maintain.

HVAC costs differ based on the work needed. HVAC systems are complex and may need a number of types of maintenance. Costs for common jobs 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 steps you can take to reduce wear and tear on your HVAC.

• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help decrease the work required from your home’s HVAC system.
• Keep your system clean. Cleaning your indoor evaporator coil, condenser fan blades, ductwork, and grills regularly helps your HVAC system work 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.
• Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the outdoor sections of your system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get out of hand.

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

Check Credentials

When selecting an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 by the state.

There are no state-level requirements in New Hampshire specifically for HVAC contractors. However, some contractors may require a Oil Heating Technician or Fuel Gas Fitting license from the Mechanical Safety and Licensing Board. You will also want to check whether your city or municipality has any local licensing requirements. Always check a provider's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, ask your installation company to provide details on the new features, energy efficiency, model, brand, and estimated installation time. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Good HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the most comprehensive protection for a fair price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote covers costs for both labor and materials. Make sure that you agree to all terms before signing the contract.
