    Service men were on time as scheduled. They were very knowledgable about their work and explained things to me as they installed boiler. I liked them being able to remove my old furnace for me. I would recommend them to anyone needing a service on their furnace or air conditioning.

Heating and Air Conditioning questions, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

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.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
