I got quotes of $35,000, $40,000 and $35000.Cut out and remove the existing cast iron hot water boiler, both hot water heaters.Cut out and remove the existing 11/2"-21/2" supply and return heating mains that run from the mechanical room (back of the house) to the meter room (front of the house).Install 2- 9 port manifold stations in the mechanical for supplying heat to the cast iron radiators.Plumb the supply and return (home runs) 1/2" pex tubing for the cast iron radiators from the manifolds to the existing branch of risers in the basement ceiling.Pressure test all piping.Pipe new 11/4"x 50' gas piping from the meter room to the mechanical room.Pressure test gas piping.Install a HTP UFT 140 high efficient modulating condensing hot water boiler and a Turbomax 45 Reverse Indirect Tank (Buffer tank and Potable hot water) with near boiler piping and controls containing:The supply and return header piping from the UFT 140 boiler to the Turbomax 45 will be piped in a 2 pipe buffer tank configuration.Isolation drain and purge valves.Air and dirt magnet separators.High efficient ECM circulating pumps with isolation pump flanges.Hydronic expansion tank with support bracket.Back flow preventer and auto filer combo unit.Inline sediment and De-minerlized filter.Controls & Wiring:Low Water Cut Off.18- Manifold Actuators.Zone Control Box's.3-Thermostats with wireless sensors.Outdoor Sensor.Cold and Hot water potable water side:Isolation valves.Thermostatic mixing valve.Thermal expansion tank with support bracketPipe 3" Polypropylene and PVC flue and air intake piping from the boiler to the outside along with a thin low profile termination kit.Install a Condensate neutralizer pump and plumb the discharge tubing from the pump to the indirect stand pipe in the mechanical room.Pressure test all piping.Install and wire in all controls in the mechanical room.Power flush the system and remove any debris that is in the radiators and piping.Drain the water out of the entire system.Re-fill the entire heating system with De-mineralized water and power purge all the air out of the entire system.Set and adjust the flow meters on the manifolds as per radiators btu's output.Perform a combustion analysis on the boiler and make any adjustments if needed.

Not only did they have the best price, but the fact that they're doing all the work should help condense the schedule considerably.Here are their bids:Click for Framing BidClick for Siding BidClick for Roofing BidClick for Door BidClick for Window BidNow that we have these bids, it really helps us validate some of our budget assumptions.

Most common problems Account Closed are putting a band-aid on a bullet hole when it comes to repairs, trying to 'make it work' with tenants who are always a slow pay and tenants not knowing how their homes work (i.e. change AC filters, clean condensers, where water shut off is,) and things the tenants can do to avoid repairs.

There were never any complaints about mold and they also forgot that they are responsible for changing AC filters every month, cleaning the AC closet door and also when the AC was repaired, it was also professionally serviced, coils and condenser fins cleaned. 

AC condenser was $3k?

Even doing comp itself is sometimes vague because like I say, comps high and comps low has three to four standard deviation, in a one million home, the range could be from $850k to $1.3mil.and to make even thing more complicated even the same house that was sold for X price in March, same house could go to 0.98x by December due to seasonality aspect of neighborhood and supply-demand dynamics.From statistical perspective, zEstimate is good when there're lot of similar comps in the neighborhood with condensed price pattern (for example, if neighborhood price is ranging from 200k-250k ; but it would be all over the place if home price is too low or too high).Even professional desktop appraisl would face similar problem as well, so I would not blame Zillow/zEstimate. this is merely statistical issue.So you still need professional appraisal.But again if you ask three different appraisar, they would come with three different opinions LOL , it's the reality.

@Jesse Smith - the cost between 1.5 ton and 2 ton is small and if the proper unit isn't installed the furnace or condenser won't be able to keep up.

There a lot of YouTube videos that give a mega condensed version of the tax lien and deed process but do not offer a step-by-step breakdown unless you agree to pay for mentorship, classes or some training program of sorts.

In particular, remove all bushes around the outdoor HVAC condenser unit...they'll get overgrown, restrict airflow to the condenser, deposit debris into the condenser, and ultimately make it less efficient.2.

See if you can fix it yourself chances are you have a problem with the fan motor, a dirty condenser or a bad relay... there not hard to work on and parts are cheap....YouTube videos can help you figure it out...
