"I received a call back from Doneright HVAC within 5 minutes of posting on Home Advisor. Garret arrived to my home in 30 minutes with his technician (as promised.) They were friendly, knowledgeable and professional. He was thorough in trying to pinpoint the exact problem and offer the most cost effective solutions, while still informing me of the inevitable need to replace my 12 year old, failing system. He even identified a faulty outlet in my attic where the units heavy plug had been attached for over a decade, and had caused some type of electrical failure resulting in Black scorch marks on both the outlet and the plug which could very possibly have turned into a house fire had it not been identified. He immediately jumped in his car and drove all the way to Home Depot to go get The necessary materials to change the plug\ outlet to a breaker protected switch, and rewired it to prevent further danger, and hardly charge me a thing for it! To sum it up; I would recommend Doneright HVAC to anyone needing HVAC service of any kind and will be keeping them as my permanent HVAC professionals! Thanks for everything guys!"

Heating and Air Conditioning questions, answered by experts

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

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.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.
