"I wanted to say a few things about this company. My other company sold to Dayco and this is my experience with the HVAC department. I called them because my upstairs unit was making a strange noise. Dakota came out and found the problem. He recommended what was needed and gave me an estimate. He was very professional. Later I spoke with Lane the service manager to ask a few questions. He was extremely helpful and also very professional. So, I will say that my first experience with Dayco was a very positive one. I would recommend anyone to give them a call."

"From the quote visit to the actual work, all the people were very knowledgeable and polite. I had multiple quotes and they were not only on par with the others I received but Guardian gave me alternative options. The gentlemen that worked my HVAC issue even took the time to pluck the little pieces of attic insulation out of the carpet that made it past the floor coverings they put down. So far so good and I am just happy that they were a no pressure outfit that seems to have gone above and beyond."

Heating and Air Conditioning FAQs, answered by experts

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.

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.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.
