"We recently moved to NJ and bought an existing home that unfortunately needed considerable HVAC and some electrical work, fortunately however, we found Dave Marshall and his crew, Don and John, of DM Solutions to fix our problems. They responded quickly with exceptional expertise, resolving every issue to our complete satisfaction and at an extremely reasonable rate. Their work ethic appears to be totally driven by customer satisfaction which we find rare this days. If you have plumbing, electrical, or HVAC issues, these are the guys to call! Sincerely, Dave B."

Heating and Air Conditioning FAQs, answered by experts

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

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.
