"I am very thankful that I found DG Mechanical on Home Advisor. After getting a few estimates from big name companies for getting central air conditioning installed in our home with existing ductwork I was getting exhausted with hearing all the upsell tactics. Derek was straightforward and prompt with all communications and very fairly priced. I felt even better after the work was done and seeing how nice and neat he left everything. While we aren’t using the air conditioner just yet it won’t be long now and we have Derek to thank during the upcoming hot summer days for keeping us cool and comfortable. I highly recommend DG Mechanical for all your HVAC needs."

So, why choose K-Wood, LLC, for your HVAC needs? The reason is we are fanatics about doing the job right. Not only do we choose the best equipment, we choose the best equipment for the job. We will also size the unit to your house. We take into account insulation, windows, and even the positioning of your house relative to the sun. We do this because a poorly sized unit is not good for anyone. If it is an air conditioner and it is too small, it will be running too much. This will increase your power bill and decrease the unit's life. If it is too large, the unit will short cycle (or turn on and off too quickly), which will also decrease the units life span. In the summer this short cycling won't allow for the humidity to be removed properly. The best equipment costs more up front, and a proper installation is not cheap either, but when you pay for both of these up front, you will have fewer problems and save a significant amount of money compared to the cheaper guy.
"This is a great company, Very honest and easy to communicate with, The technician arrived on time and took care of the probably with ease."

Heat pumps don’t create heat—they move it. A refrigerant cycles through two coils, picking up warmth from outside air in winter and releasing it indoors. In summer, the process reverses, pulling heat out of your house and sending it outside. Because the system simply transfers energy rather than generating it, you get efficient, year-round comfort without burning fuel.
With proper installation and regular upkeep, a quality heat pump typically lasts 12 to 20 years. Swap or clean filters as directed, book an annual tune-up, and tackle small repairs quickly to keep the system running smoothly. Skipping maintenance can shave years off the life span and undercut the energy savings you expect.
Heat pumps shine in areas where winter temps stay above about 40°F. Below that mark, efficiency drops, and once readings dip under 25°F you’ll want a backup heat source. Choose a model with a high Heating Seasonal Performance Factor (HSPF) and budget for supplemental heat if your region sees deep freezes. That combo keeps comfort levels high without driving up utility bills.
The biggest drawbacks are the up-front price tag and lower efficiency in extreme cold. If winter temps in your area drop below 10°F, the outdoor unit can freeze, and you may need electric upgrades or duct tweaks to keep things running. Factor in these extras before you buy so the long-term savings aren’t wiped out by surprise costs.
