"Excellent Service! I highly recommend the Capitol Region Plumbing and Heating Services LLC! Avi, and Sean came to my home immediately when I needed their help with bathroom plumbing and a water pump system. They were courteous, knowledgeable, and thoroughly evaluated the problems. Their excellent assessment and quality of work were evident as I looked at their pictures of before and after replacements of PVC pipes for main sewer lines, sink and shower drains, and water lines for the toilet. Also, Avi and Sean installed a new well pump and pressure tank system. They even came to my home on a holiday to assure me that I'd have water. As true professionals, Avi, and Sean are efficient, punctual, and reputable. Their work ethic is commendable and gracious manners are exceptional. This was an incredible plumbing service that everyone expects and appreciates!"

Heating and Air Conditioning questions, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

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.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
