Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward. He came today as promised and found that my thermostat only needed batteries, but my system was otherwise fine. He is very good and extremely honest and informative."

Heating and Air Conditioning questions, answered by experts

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.
