"He reattached the air condition hose to the vent but never came back with the part he said I needed and would not return my calls. He never finished the job. I hired someone else to complete his work. Beware."

"Scott was great, offered a fair price, was flexible for scheduling, and finished the job quickly and well. We had a Bath fan install + an exterior electrical outlet installed and he was able to get it done within a few hours. The install looks clean and he took care to clean up afterwards too. Great work Scott! Thank you!"

Hvac Repairs questions, answered by experts

Some states require special licenses for HVAC professionals, but most don’t. However, even if there is no state requirement for HVAC licensing, local requirements might exist. It’s always a good idea to check if HVAC technicians need to be licensed in your area and then Angi’s contractor license lookup tool to confirm that the contractor you’re hiring holds the necessary licenses. Additionally, you should always ensure the company you’re hiring is fully insured to avoid potential lawsuits if a technician gets injured on your property.

A dirty or clogged air filter is the most common reason a furnace stops working. Over time, the filter can become laden with dust, debris, and contaminants, obstructing airflow and causing the furnace to overheat. This overheating triggers a safety mechanism that shuts down the furnace to prevent damage or fire hazards. Regularly replacing or cleaning the air filter is essential to maintain proper airflow and ensure the furnace's smooth operation.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

Gravity furnaces, even when wrapped in asbestos, are generally considered safe. They become much less safe if any of the asbestos is removed or damaged, as it then spreads through the system into the house. Only a professional will be able to tell you if your gravity furnace poses a danger to your health or your home. After a proper assessment, you’ll be able to decide if replacing it is worth the time and investment.
