"He gave us an estimate then went to Home Depot to get supplies, for which we paid. He spread a drop cloth on entry pavement. He removed old pain pieces on frame, cut the screen he bought in half and screwed them to the bottom of each door. He then spray painted the doors white. The doors needed more paint, so he went to Home Depot again and bought additional cans of paint (12 in total). I got sick from the paint smell, so my sister took over. When he finished she paid him. When I was able to inspect the job, I saw a hole in one doors screen and long screws sticking out 3/4" on both screens. I sent hime a text message to his phone, but got no response, so I phoned him to discuss the matter. He said his drill slipped punching to hole in the screen and that's the only screws he had. He said the screen is too expensive to replace and the screws are it. He said he"

Heating and Air Conditioning questions, answered by experts

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

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.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
