How to Choose the Right HVAC Technician

Your HVAC system keeps your home comfortable year-round. Whether you need a repair, seasonal tune-up, or full system replacement, hiring the right contractor is the first step to making sure the job gets done right. This is what Modernize recommends:

  • Ask Around: Start by talking to friends, family, or neighbors who’ve had good experiences with HVAC techs. Online reviews can also give you a good sense of their reputation.
  • Check Credentials: Make sure the technician is licensed and certified. This guarantees they know what they’re doing and can handle your system safely.
  • Get a Few Quotes: It’s always a good idea to get quotes from at least three technicians. This helps you compare pricing and services. Modernize can connect you with vetted contractors so you can do this step a lot more easily.
  • Look at Experience: Ask if they’ve worked with your specific HVAC system or brand. Experience with your system means quicker, more reliable service.
  • Read Customer Reviews: Check reviews to see what others are saying. Positive feedback is great, but it’s worth reading the negative ones to get the full picture.
  • Ask About Warranties: Make sure to ask about warranties or guarantees on the work. A good technician will stand behind their service.

What Is the Cost of a New HVAC System Near Me?

The national average cost to install a new HVAC system ranges from $6,200 to $12,000, with most homeowners spending around $9,600.

What affects your final cost?

  • System Size and Type: Central air, ductless mini-splits, and heat pumps have different price points and energy demands.
  • Home Size: A larger home may need a higher-capacity system, which costs more to install and operate.
  • Energy Efficiency: ENERGY STAR® models and high SEER-rated units save on energy but usually cost more upfront.
  • Ductwork: If your ducts need repair or replacement, it can add to the total price.
  • Installation Complexity: Multi-zone systems or tricky attic installs take more time and labor.

How Much Does HVAC Repair Cost?

The average HVAC repair costs between $150 and $600, depending on the issue. Many HVAC technicians charge between $100 and $150 per hour for their services. If you need any replacement parts, that adds to the total cost. Most homeowners pay around $350 for minor HVAC repairs.

These are a few factors that influence repair costs:

  • Type of Problem: Replacing a thermostat or cleaning out blocked vents is cheaper than fixing a compressor or blower motor.
  • Necessary Parts: If the repair requires replacement parts to be installed, you’ll have to pay for the parts and the installation. Replacement coils, for example, cost an average of $1,200!
  • System Age: Older systems may require harder-to-find parts or more labor.
  • Time of Year: Emergency repairs during peak heating or cooling seasons may come with extra charges.
  • Warranties: Check if your system is still under warranty — some parts or labor might be covered.

Signs Your HVAC Needs Servicing

Catching HVAC issues early can help you avoid bigger repairs or system failure. Here are common signs it’s time to call a pro:

  1. Warm air from your vents during cooling season (or cold air during heating season)
  2. Weak airflow
  3. Higher-than-usual energy bills
  4. Odd smells or loud noises coming from the unit
  5. A system that cycles on and off too often

Signs of an Emergency HVAC Issue

While many issues can wait a few days to be serviced, some HVAC problems need immediate attention. Call for emergency service if:

  1. You smell burning or see smoke coming from your unit
  2. There’s no air coming from the vents and the system won’t turn on
  3. You notice leaking refrigerant or water pooling around the unit
  4. Your home’s indoor temperature becomes dangerously hot or cold

What Services Do HVAC Companies Offer?

HVAC companies do more than just fix broken systems. Many offer a full range of services to help keep your home comfortable all year long. These are some services that many of them offer:

  • System Installation: This includes new HVAC systems for homes under construction or replacing outdated units with energy-efficient models.
  • Repairs: From broken fans to faulty thermostats, technicians can fix heating and cooling issues quickly and safely.
  • Routine Maintenance: Seasonal tune-ups help catch small problems before they turn into expensive repairs and ensure your system runs efficiently.
  • Air Quality Improvements: Many companies install or service air purifiers, dehumidifiers, and ventilation systems.
  • Ductwork Services: Whether you need a repair, cleaning, or full replacement, your HVAC pro can inspect and improve airflow in your duct system.
  • Smart Thermostat Installation: Professionals can recommend and set up thermostats that help you save energy and allow you to control your system remotely.
