"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

Hi every body, this is Oscar and I know the quality of work I can do for you. I have maintenance experience from different companies. My work is about painting, some flooring, drywall repairs, appliances troubleshooting, gutters and roof cleaning, downspout, dryer vent cleaning and general cleaning services at home. Anything I can help let me know. I speak English, Spanish, and Italian if it’s needed.

"Top marks all the way around for Oscar. Oscar is the best handyman we’ve ever employed. He was everything you want in someone working on your home: excellent communication, reasonable cost, high quality work, prompt, dependable, friendly, neat, cleans up after each day of work, very detail-oriented, and just a really nice guy. He re-screened our 3-season porch, replaced all the exterior wood facings on the porch, hung a new and much improved door on same porch, replaced about 12 feet of cedar privacy fence, and power washed the full exterior of our house. There is no question that we will call Oscar again when we need work done. If you’re looking for a talented handyman, look no further; just call Oscar. "

Boiler Repair questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Many states don’t have specific license requirements for HVAC repair companies, but your local city or county might. You can check online for local requirements and then Angi’s contractor licensing tool to see if the company you’re considering is licensed. Regardless of licensing, you should ensure your company is fully insured. We recommend checking to see if the company holds third-party certifications, including North American Technician Excellence (NATE) certification and R-410A certification, which qualifies your provider to work with HVAC refrigerants.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.
