My landlord originally hired someone to fix my heater, but after multiple attempts they couldn’t figure it out. I finally decided to call Alden from Dolcini’s Heating and Air, and I’m so glad I did. He quickly identified the problem, explained everything clearly, and got my heater working...

terrific job on a very complicated installation. Water heater serves house and under floor heaters.
We had an electrical water heater that shorted out. Based on the description and age of the water heater, Paladin determined that it would not be worth trying to repair. So we schedule a replacement for same day. After examining the water heater first hand, it definitely was the right call....

"I got bids from a *large* number of installers and Red Mountain gave me the best equipment for the price and did a nice job of it despite a few early teething problems that were resolved quickly and competently. But note that the going price in this area for heat pumps is significantly higher than in other areas of the country - regardless of which installer I let bid on my home. In my opinion, given energy price trends, the environmental impact of heating with gas, and having existing solar power on my home, the benefits of a heat pump outweighs the high price in this area, but YMMV. Think thru your position re: BayREN rebates and the recent federal Inflation Reduction Act rebates carefully to make sure you qualify."

Heating Oil questions, answered by experts
Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).
Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.
Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.
