"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."

Heating and Air Conditioning questions, answered by experts

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
