10 Best HVAC Companies in Durham, NH

Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:

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

If you see any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and determine whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Durham

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

• Split or mini-split: Homes without ductwork for central heating and cooling often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. They don't make their own heating and cooling, so they work more effectively in more mild climates.
• Packaged heating and air: Packaged HVAC systems are a practical choice for smaller houses. These systems have a single combined AC and heating, typically located in an attic or basement. They're space-saving, cost-effective, and easy to maintain.

HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complicated and might require different kinds of maintenance. Prices for some common services are as follows:

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your HVAC.

• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get out of hand.
• Keep your system clean. Cleaning your grills, condenser fan blades, indoor evaporator coil, and ductwork regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
• Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow efficiently through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
• 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 reduces the amount of work your HVAC system must perform.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor 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 providers for quotes. Explain 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

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on what kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

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 should also check whether your city or municipality has any local licensing requirements. Reviewing feedback on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can assist your decision. Choose a provider with stellar reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts need replacement and why. Confirm that your technician will clean and test the full system after finishing the work to ensure proper operation. For replacement, ask your contractor to explain the new HVAC system model, brand, energy efficiency, features, and estimated installation time. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review warranty terms for each contractor and choose the provider that offers the best protection at a reasonable price.

Get Quote in Writing

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