"The latest visit diagnosed a failed ignition valve which needed to be ordered and replaced. They arrived promptly, assessed, diagnosed and ordered the parts immediately. It only took a few days for the parts to arrive and they were able to schedule me in for the service call. The first technician was able to maintain the ignition valve until the new part was available, which was directly responsible for heating my home. The second technician installed the part and was able to assist me in some technical updates on the app and digital thermostats. I learned so much from Michael and appreciated his knowledge and patience. He also fixed a safety issue on the second level and adjusted the air flow for the system. The system sounds so much quieter. It was a warranty issue with no cost."

"Bobby came out and installed a complete Trane system and even relocated the furnace and A/C compressor to a more sensible location. The installation crew was polite, professional and efficient. The new heating and air system works flawlessly. Best service I have ever gotten from a HVAC company ever!"

Heating and Air Conditioning questions, answered by experts

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

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.
