"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"Top quality work on short notice. I cannot be more pleased with how they helped us by inspecting the oil boiler and multiple HVAC systems prior to settlement on our new home which was built in 1971. Now we have complete knowledge and piece of mind concerning these systems. Dominion will be our "go to" contractor for maintenance and service calls."

\n\nHi, I'm Jason, owner of TriFixCo, a locally owned handyman service based in Clayton, NC. I keep my service area close to home, serving Clayton and the surrounding Raleigh area, so I can show up on time and give every job real attention.\n\nBefore starting TriFixCo, I spent years in building materials sales: windows, doors, trim, trusses and lumber. That means I know what products hold up, what they should cost, and how they should be installed. I've also done plenty of hands-on work myself, including drywall repairs, flooring and trim installation.\n\nI also have a background in customer service leadership, so I believe in clear communication, upfront pricing, and leaving your home cleaner than I found it. Whether it's a punch list, a repair that's been bugging you, or a small install, I'll give you an honest quote and do the job right.

"Vendor install a Honeywell 7200 series thermostat in my new home, but I decided to upgrade to a 6580 WiFi unit. I did all the work myself but couldn't get the A/C to work. I called Honey well who referrred me to Enhanced Heating and A/C. I called them at 3:45 PM on a Friday afternoon and got a live person who said someone will call me back after I presented the problem I had. Around 4 PM I got a call from Sean who helped me out with the wiring and the A/C is now working."

Boiler Repair FAQs, answered by experts

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.

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.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
