"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

Air Conditioning questions, answered by experts

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
