"Everyone we worked with at Prudhom Heat & Air was courteous and professional. This family-owned business offered a good product at a fair price that met our needs perfectly. There was one small issue a few days after the installation but we called and they were back out within 30 minutes and had the problem resolved in less than an hour. We'll definitely use them for our future HVAC needs!"

"Keaton was exactly what O should have had the first 2 times! He came in and told me everything he was doing. He had it going in less than 20 minutes!! I paid less than the other two companies who left me with no heat both times. This company is what you need do not waste you time with anyone else!!!! To be honest they left it better than anyone else had!!!"

Heating and Air Conditioning FAQs, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

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.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.
