I pride myself on my diligence and attention to detail, and make a dedicated effort to reduce repair/installation cost.

Heating and Air Conditioning questions, answered by experts

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

A new HVAC unit typically adds about $2,500 to $3,000 to the value of your home or about 5% to 7% of your home’s value. Since a new unit can cost up to or more than $10,000 to install, it’s up to you to decide if the upfront cost is worth the added value. Consult a local AC installer to determine next steps.

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

HVAC technicians charge around $175 per hour, but anywhere between $100 and $250 per hour isn’t uncommon. The total cost of your HVAC service depends on the type of work, the type of system, and more. Here are some important cost factors to consider to get accurate pricing:

  • Time of year

  • Urgency of your repair or service

  • Type of system 

  • Type of repair you need

  • Whether or not you have a service contract

  • Size of your HVAC system

  • Brand of HVAC equipment

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
