"I hired Joe to inspect and clean my AC system. I will have him come back this Fall to do the same for the furnace. He was completely honest and made sure I wasn't paying extra for anything I didn't need. He recommended topping off the refrigerant, but said it wasn't necessary, and was upfront about how much he charges per pound of R-22 and how much my system might need. Joe also gave me advise on what maintenance I should regularly do. The pricing was reasonable and probably the cheapest around. He is now going to be my goto HVAC serviceman. I would have no problem recommending him to family and friends."

"The man who came to my house to describe the furnaces and help determine which one I wanted could not have been more wonderful. He was helpful and efficient. We had agreed on a week when the work would be done. The installers called and wanted to come a week earlier. I okayed it, but it wasn't the best day for me. They were nice and efficient. The new furnace appears to be exactly what I wanted. However, the new thermostat control was a different size and shape from the original one and they didn't patch the holes or repaint the edges--not a big deal but when I got a security system a few weeks ago, they did do all that finishing."

Heating and Air Conditioning questions, answered by experts

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.
