"Every interaction with these people felt like I was talking to a used car salesman....they actually brought a pound of coffee to the visit like they were selling Rainbow vacuums. Marketing techniques aside, they claimed I needed an entirely new unit at an estimated cost of $8-$9000, and then never sent a written estimate. I contacted another company, who cleaned the unit and replaced a defective blower. Total cost: $900. To follow up on their Google response: Although my wife made it very clear we were looking for just a repair, I was called within seconds of the tech leaving our house by Grasshopper’s offices to set up an appointment to “get measurements for a replacement unit.” So, no, we didn’t ask for a replacement at that time, but Grasshopper was more than happy to push for that (far more expensive) option. Wonder how often that happens with your other customers? And again…we never received an invoice at any time, for any level of repair or replacement, so we couldn’t examine our options. With that said…I’d be happy to pay the outstanding invoice…if you actually sent one of those either. (For reference, the company we had the repair completed through was paid the next day.) Thanks for passive-aggressively mentioning that in your response though. Very professional. So, I guess since your organization has no clue how invoices work, I need to show up and pay with cash? Regardless, I want to get you guys paid so I can forget you exist, except when I tell this story to anyone looking for heating services recommendations in the future."

Heating and Air Conditioning questions, answered by experts

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
