10 Best HVAC Companies in Durham, NC

Signs You May Need HVAC Repair or Replacement

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

• Uneven heating/cooling or poor air circulation
• Frequent breakdowns and need for repairs
• Thermostat malfunctions or temperature control issues
• Odd noises when the system turns on
• Unusually high energy bills
• Refrigerant leaks
• Corrosion, cracking, or rust
• 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 identify problems and recommend whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Durham

The price of HVAC installation or maintenance varies depending on the type of unit you have. Common types of HVAC units include the following:

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage 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 generate their own heat or AC, so they perform best in mild climates and may not be as effective during Durham's hot summers.
• Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single cooling and heating unit, normally in an attic or basement. This unit is often small, cost-effective, and easy to maintain.

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

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Fortunately, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

• Keep your system clean. Cleaning your grills, ductwork, indoor evaporator coil, and condenser fan blades 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 when it begins to look dirty.
• Change filters regularly. Switching out your air filters or washing them every 1–3 months allows smooth air circulation through your HVAC system. You should also try to keep debris from accumulating on the outside components of your HVAC.
• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your HVAC system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get out of hand.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with skilled technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the type of 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 at the state level.

In North Carolina, HVAC contractors are required to be licensed through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. Not all individuals who work for a licensed firm need to be individually licensed; however, all work must be supervised by a licensed contractor. Contractors may hold multiple different licenses for different jobs. You should also look at a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Make sure you know the details of your project before starting. When getting HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask the installation company to provide details on the new energy efficiency, features, brand, estimated installation time, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

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

Get Quote in Writing

Get written bids before starting any HVAC work. The quote should include costs for both labor and materials. Read all terms carefully before signing.
