"I was referred to Paze Heating and Cooling by a well-respected friend, and I immediately understood why. I have referred this company to several others and will continue to do so. Mr. Zeno Pace and his team are expert technicians. His responsiveness is very timely and his pricing is well worth the level of service he gives. I recently had an A/C problem that was covered by my home warranty company. Mr. Zeno helped me understand and articulate the repairs needed so that I would not be taken advantage of by the other contractor. Ultimately, I was taken advantage of by the other contractor, and Paze Heating and Air came to the rescue. Mr. Zeno responded immediately and fixed the damage the other contractor left. You will not go wrong with Paze Heating and Cooling."

Heating and Air Conditioning FAQs, answered by experts

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
