10 Best HVAC Companies in Newmarket, NH

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 servicing or replacement from an HVAC company. Look for these indicators your system needs service:

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

Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, identify problems, and figure out whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Newmarket

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

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either gas or electricity for power.
• Heat pump: Heat pumps work by moving warm and cool air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more effective in more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. They have a single heating and cooling unit, typically in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be costly. Luckily, there are actions you can take to minimize wear and tear over time on your system.

• Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 30–90 days. Also try not to let debris pile up on the external sections of your HVAC.
• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. 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, indoor evaporator coil, ductwork, and grills clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating 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 contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians with 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 required for all contractors 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 what kind 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 Fuel Gas Fitting or Oil Heating Technician license from the Mechanical Safety and Licensing Board. You will also want to check whether your city or municipality has any local licensing requirements. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

Always make sure you know what a company’s process looks like. When getting HVAC repairs, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test your system after finishing the work to ensure proper operation. When replacing your HVAC, ask your installation company to provide details on the new features, brand, model, energy efficiency, 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

Reputable HVAC companies stand behind their services with warranties. Look at warranties from different companies, while remembering that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written estimate before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
