"Jamie was without a doubt the best HVAC technician I have ever dealt with. He responded to my service call faster than I expected and went above and beyond to repair my furnace. He explained everything up front and did the repairs very quickly. I will be using him for all my HVAC needs from now on!"

"We would highly recommend JMSM. John was extremely personable,professional and thorough. We had our gas fireplace inspected and cleaned and John took the time to inspect and test all parts. As a bonus, he educated us on the use in emergency situations...such as power outage. We are very happy."

"Impressed is an understatement! I called Apex when my mom's water heater went out and the company her home warranty sent couldn't repair the shut off valve. They came within 1.5 hours of me calling and were amazing. They repaired the shut off valve and took the time to explain everything. We were so impressed we had them install the new hot water tank instead of using the home warranty company. Charles was able to do everything the same day and worked around the water mitigation company. He was so professional and did a great job. We will definitely be using them for all our future plumbing needs!"

Heating and Air Conditioning questions, answered by experts

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

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.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
