"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"On Monday, May 12, our A/C wouldn't turn on and was scrambling around trying to find someone to fix our A/C ASAP since this weeks forecast weather is going to be hot.  I called a few repair companies and the closest appointment is on Wednesday.  Left a message with this company and Nick called me back.  Nick came over to fix our A/C on the same day.  He was prompt, friendly, professional and got our A/C working.  I highly recommend this company and I will use their services again.

"Repair was done on my daughter's car who is in college in California, I live in Colorado. The owner spoke with me on the phone prior to doing the repair to explain issues with car. His assessment was consistent with the problems my daughter described to me. The price was very reasonable for all the parts and labor. The job was completed quickly and they stayed past closing until my daughter could get there to pick up car. They accepted my payment over the phone and offered to check her fluids and inspect car periodically in the future for free. I think you will be very satisfied using this garage as this and other reviews have clearly shown.

"The technician looked at the washing machine & found that there was a major problem with it, requiring the replacement of a very  expensive part. The cost to repair it would have been over $500, so we both agreed it would be better for me to just get a new washing machine. Normally, they charge for the service trip, but because the problem couldn't be fixed they gave me a great discount on it. I will definitely use this company again.

Boiler Repair questions, answered by experts

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

The average cost for HVAC repairs is approximately $350. However, prices can range from as low as $100 to as high as $3,000 or more, depending on the type of repair and the extent of the damage. For example, a relatively inexpensive capacitor replacement may cost $100 to $500, while a major compressor repair can range from $750 to $2,000. Other common repairs and their typical costs include:

  • Blower motor repair: $200–$500

  • Circuit board repairs: $100–$600

  • Evaporator or condenser coil repair: $400–$1,500

  • Heat exchanger repair: $100–$200

  • Thermostat repair: $175

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

Costs depend on issue severity, parts needed, and labor rates.
