"After shopping around I selected BKR Plumbing and Heating because their prices were fair and they made time in their schedule to get my job done. My hot water tank was leaking and I did not want to wait until my basement was flooded. They came right on time with the proper parts and tools to do the job. Their work was neat and quick. I am very happy the the job they did."

Heating and Air Conditioning FAQs, answered by experts

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.
