"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"I recently bought my house in May and oh my God the sun was really keeping me hot in there. Something had to change, and that's when I started looking for someone to put in a ductless ac system. Wise came out gave me an estimate and it was the best I heard. They were very professional and neat with the job, and my house is no longer a sauna. I can say that I would easily recommend them to others as I know they would do a great job."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

Air Conditioning questions, answered by experts

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.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

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.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
