Customer Testimonials – See What Our Clients Say!

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.

Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!

Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

FAQs for San Francisco Residents

Can I Claim HVAC on My Taxes?

Yes, you may be able to claim HVAC expenses on your taxes if you’ve made energy-efficient upgrades to your home. Under the Federal Energy Efficiency Tax Credit, you can claim a credit for qualified HVAC systems, such as energy-efficient air conditioners, furnaces, and heat pumps. The credit amount depends on the specific system installed and the requirements outlined by the IRS. Be sure to consult with a tax professional for guidance on eligibility and the necessary documentation.

How Long Should a Residential HVAC System Last?

A residential HVAC system typically lasts between 10 to 25 years, depending on the type and regular maintenance. Furnaces generally have a lifespan of 15 to 20 years, while heat pumps typically last around 10 to 16 years. The longevity of your system can be extended with regular maintenance, such as cleaning filters, checking for leaks, and scheduling professional inspections to ensure it runs efficiently throughout its lifespan.

Do HVAC Companies Charge for a Quote?

Many HVAC companies do charge for a quote, especially if they need to conduct an on-site inspection to assess the scope of work. However, some companies offer free estimates for basic repairs or installations. It’s always a good idea to ask upfront whether a quote will be free or if there will be a charge, so you know what to expect.

Why Is Replacing HVAC So Expensive?

Replacing an HVAC system can be expensive due to the cost of the new unit, labor for installation, removal of the old system, and potential ductwork modifications. Additional costs may include permits and upgrades to meet local codes. However, an energy-efficient system can lower long-term operating costs.

How to Find a Reputable HVAC Company?

To find a reputable HVAC company, check for proper licensing and insurance, read online reviews and customer testimonials, and ask for referrals from friends or family. Ensure they offer written estimates and provide transparent pricing. Look for companies with experience, positive track records, and a guarantee on work. Always choose a company that meets local codes and offers 24/7 support.
