10 Best HVAC Companies in Merrimack, NH

Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and recommend whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Merrimack

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

• Split or mini-split: Homes without ductwork for central air frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature, which all 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 transfer hot and cool air between your home and the outdoors. They don't make their own heat or AC, so they function best in temperate climates.
• Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. These systems consist of a single heating and cooling unit that's typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC costs differ based on the services needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC 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. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both decreases the amount of work your HVAC system is required to do.
• Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow efficiently through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
• Keep your system clean. Keeping your grills, ductwork, condenser fan blades, and indoor evaporator coil clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice it starting to get dirty.
• 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. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states need to 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." Contractors must pass an exam (the type of exam depends on the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.

New Hampshire doesn't have specific state-level licensing requirements for HVAC contractors. However, in certain cases, a contractor may require a Oil Heating Technician or Fuel Gas Fitting license from the Mechanical Safety and Licensing Board. You will also want to verify whether your city or municipality has any local licensing requirements. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with positive reviews and reports of fantastic customer experiences.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC, ask the installation company to provide details on the new estimated installation time, features, brand, model, and energy efficiency. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Reliable HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

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