Do not hire them. Huge huge integrity issue. They came to diagnose my heat pump/ac unit figured it out. Well because I didn't hire them on, they pulled the breaker out on the outside box so my ac wouldn't work - which was working prior to them leaving. I have 2 kids just unbelievable.

Heating and Air Conditioning questions, answered by experts

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

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.

Zoned HVAC systems can be worth it for some homeowners, even with the added HVAC replacement costs, because they offer tremendous benefits. Zoned HVAC may offer greater stability and efficiency if your home has multiple levels and experiences constant temperature fluctuations. However, even smaller homes without major fluctuations can benefit since zoned HVAC systems can adjust their temperature more quickly by heating and cooling only the spaces you need.

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.
