"Updated 4/25/2025 review: would be delighted to change this back to 5 star, but no way at this time. 1 reply since 4/14. No followup; can't coordinate with roofer to actually install A/C unit to my home (each says they will, but neither does), months after it was craned to the roof. Only half the house has A/C, and the single unit working cannot cool the whole thing below 76°. Horrible in 80+° heat. Need relief, and very much not getting it here. Very unprofessional and unethical."

Heating and Air Conditioning questions, answered by experts

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.

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.
