"Our overall experience with Honest Abes for our HVAC replacement went quite well. Equipment, techs, timing was all 5 star. My 4 star rating is for the contractor not providing the manufacturers warranty info. Honest Abes provided thier warranty but l wanted all the warranty info. I went to Goodmans site, entered all serial numbers and received all my data related to our HVAC system. It even list the built date of each item. If Honest Abes starts leaving the manufacturers warratny with their installs, l believe most customers would be more satisfied."

Heating and Air Conditioning questions, answered by experts

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.
